Zmanda Windows Client Users Manual

Introduction   

Zmanda Windows Client (or ZWC) backs up data from Microsoft Windows clients to an Amanda backup server.  Zmanda Windows Client has 32bit and 64bit installers for respective architectures. Zmanda recommends the latest Windows service packs must be installed as recommended by Microsoft.  The list of Windows platforms and applications supported are documented in the supported platforms matrix.  

   

Requirements   

Zmanda Windows Client uses Volume Shadow Copy services. Volume Shadow Copy service must be started and not be disabled on the Windows client.  

Windows clients must open inbound TCP ports 10080 and 10081, and outbound TCP ports 800:840. On Windows 7, 8, 10 and Windows server 2008, 2012, 2016, 2019 ZWCService.exe added to the "Exceptions list" during ZWC installation if the Windows firewall is turned on.  Please ensure that these ports are not used by other software. Some Anti-Virus software is known to use these ports. Please contact Zmanda Support if you need help in avoiding port conflicts.  

The Zmanda Windows Client utilities such as ZWCconfig and ZWCsupport must run as Administrator (either logged in as Administrator or by right-clicking the utility from the Windows Start menu and choosing Run as administrator).  

 

Downloading and Installing/Upgrading Zmanda Windows Client   

Important Note: During installation, an amandabackup user account is created on the Zmanda Windows Client using local rules (i.e., Domain Controller/Domain/Standalone Workstation) for password creation. These OS users run backup and restore processes. When you change the account passwords eventually, be careful to ensure that security policies (such as strong passwords, password expiration) are followed. If an amandabackup user password expires, the Zmanda Windows Client service will fail to start, returning a Login Failure message.  

You can upgrade from Zmanda Windows Client 3.1.4,3.3,3.5 and 3.6 to the latest 4.1 version.  

 

1. Download the Zmanda Windows Client software from the Zmanda Network downloads page. Please have your Zmanda network Username and Password ready; you will need them to access the download page. Depending on the licenses you have purchased, the downloads page will let you download packages for 32-bit and 64-bit server and desktop installation options. 
   Desktop versions are required for Windows 7, 8 and 10, server versions are required for Windows 2008, 2012, 2016 and 2019 server. You should install the 32-bit version on 32-bit platforms and the 64-bit version on 64-bit platforms.  
2. Extract the zip file to the appropriate Windows machine and run the Setup.exe program. Do NOT upgrade if there is a backup or restore to the Windows machine in progress.  
3. The installer automatically detects if it is an upgrade from an earlier version of Zmanda Windows Client. Please preserve the configuration and database contents.   
4. Follow the on-screen instructions. When asked to select an installation directory, you may want to change from the default location (C:\Program Files), as the Zmanda Windows Client internal databases can consume a lot of disk space, and also affect the performance of other applications that depend on the same disk when processing backups. If you are installing in an alternate location, the alternate folder must be owned by the Administrators group. You will also need to set a password for the amandabackup user on the Windows client. You will also need to know the Fully Qualified Domain Name or IP address of the Amanda server to which this client will back up. Multiple Amanda servers can be added using comma-separated syntax.  

 

Unattended Windows Client Installation/Uninstallation   

  

If you are planning to install Windows Client on multiple machines, you should record the user input for playback. Using the user input recorded file, you can install Windows client using the command line on multiple machines in an unattended manner.  

 
To record user input, run  

setup.exe /r /f1<recording file>  

The recording file will contain all user input for playback.  

Windows client installer can read the user input recorded file from the same directory. Alternate location for user input can be provided using /f1 option. The installation log file will be created in the same directory (default: Setup.log). Alternate location for the log can be provided using /f2 option. An example command for replaying user input from C:\Temp\Setup.iss file.  

setup.exe /s /f1"C:\Temp\Setup.iss"  

 
The command will complete before the installation or uninstallation process is completed. Use /WAIT flag if you want the setup.exe command to wait for the process to be completed. For example: Run the following installation command that will wait till process is completed in Windows command shell  

start /WAIT setup.exe /w /s /f1"C:\tmp\Setup.iss''  

The Zmanda Windows client zip archive file (downloaded from Zmanda Network) provides default install.iss and uninstall.iss that can be used of unattended installation and uninstallation. This example setup files assumes 

1. Zmanda Windows Client will be installed in the C:\Program Files\Zmanda\Zmanda Windows Client folder. The amandabackup password will be password 
   
2. Zmanda Windows Client uninstallation will not preserve configuration data.  

Installation Troubleshooting   

If the installation failed for some reason, the ZWC installer rolls back the installation to the last working configuration.  

The installation program logs messages to the following locations:  

• The Windows $temp directory (MSIMM:DD:HH.txt). The MSI-generated files are named by date and time rather than by the software being installed.  
•  Successful installation messages are logged to C:\Program Files\Zmanda\Zmanda Client for Windows\Debug\LogFile.txt.  
•  Installation failures are logged to C:\zwc_install.log.  

Installation can fail for a variety of reasons. For example, the user set a Password not conforming to Windows requirements, or running the installation program without the necessary permissions. The log messages will explain what went wrong.  

Changing the Location of the Installation Data Directory   

  

The Windows Client Installation Data Directory contains following critical folders:  

 

• c:\program files\zmanda\zmanda client for windows\MySQL\data is where the catalog file(s) are stored. If you move these files, the new location must be specified in the ZWC my.ini file. This database stores the list of files backed up along with their metadata. This information is stored between full backups so that files already backed up are not included in incremental backups. A full backup of a directory will cause all the information stored about earlier incremental backups to be removed (and hence the database size is reduced). The size of the database is directly proportional to the number of files in the directory or volume being backed up. We recommend at least 1GB of disk space allocated for the catalog.  
•  c:\program files\zmanda\zmanda client for windows\misc is where the backup set header files are stored. This location can be changed using the ZWCConfig utility.  

 The database stores the list of files that are backed up and their meta data. This information is stored between full backups to track what was backed up and determine what should be backed up in incremental backups. Doing full backup of the directory will cause all the information stored about earlier incremental backups to be removed (and so database size will be reduced).    The size of database is directly proportional to number of files in the directory or volume being backed up.

If you find that the ZWC installation folder runs out of disk space while processing backup sets, you can move location of these files. There are two methods of doing this:  

• By uninstalling ZWC and re-installing it on a different volume (preferred).  
•  By manually moving the catalog and backup set header files and editing the my.ini file and Windows Registry to specify the new locations (see the steps listed below).  

1.  Use the Control Panel to stop both the ZWCService and the ZWC-MySQL services.  
2. Move the data directory under ZWC_Installation_Directory\MySQL\Data to the new location. For example, move C:\Program Files\Zmanda\Zmanda Client for Windows\MySQL\data to F:\MySQL\data.  
3. Open ZWC_Installation_Directory\MySQL\my.ini and put the following entry under the [mysqld] section: 
   

 
---------------------------------------------- 
[mysqld] 
datadir=SQL_data_dir 
 
---------------------------------------------- 
where SQL_data_dir is the new data location. 
   

4. Run the ZWCConfig utility. In the Advance tab, edit the location of temp dir.  
5. Start the ZWC-MySQL service.  
6. Start the ZWCService service.  

 

Backing Up Windows Clients   

Windows clients can be backed up using a number of different methods. The method you choose will depend on:  

•  the version of Windows running on the client  
• whether applications are being backed up  
• other requirements you might have for backing up Windows servers and workstations.  

There are four methods that require the Zmanda Windows Client (CIFS/Samba-based backup does not require that the ZWC is installed):  

•  Windows File System (NTFS/ReFS)  
• Windows System State backup provides a point-in-time snapshot of core Windows system files (including registry, Active Directory).  
• Windows Templates are useful when you wish to  

o     Create a consistent backup of files/directories across drives and partitions on a Windows client.  

o     Configure pre-backup and post-backup scripts on the Windows client to perform such actions as deleting temporary files, sending out user notifications, etc.  

• Windows Application Agents: These separately-licensed modules allow you to backup applications such as Exchange, Oracle, and Microsoft SQL.  See the Zmanda Application Agents guide for details.  

ZMC/AEE allows concurrent backups of at most one application backup object (such as Oracle or MS Exchange) and either one Windows filesystem backup object or one Windows template backup.  Editing DLEs using the ZMC will result in all windows backup object/DLEs having spindle values supporting this behavior.  

However, note that the Windows template backup object type does support multiple concurrent file system-based DLEs (for example, the Program Files and My Documents folders).  

Please make sure no other backup software is scheduled to run at the same time as the Amanda Windows Client backup.  

 

Windows File System Backup   

  The Zmanda Management Console (ZMC) allows backup objects (also known as Disk List Entries or DLEs) with different Host Types to be included in the same Backup Set. Disk List Entries for Windows Clients resemble entries for other host types (Linux, Solaris, etc.).  

 

 

 

 

Please see Zmanda Management Console Sources documentation for details on exclude files and compression. Windows client compression uses ZIP deflate algorithm. It is not possible to change the compression algorithm used on the Windows client.  

Enable client encryption while creating the source on Sources page for the Windows DLE that needs to be encrypted on the client.  The key to be used for encryption should be specified using the Advanced Settings in Zmanda Windows Client Configuration Tool. For more details on Windows client encryption please see Windows Encryption section.  

Note : Data Integrity Check is not valid if we add Windows DLE with encryption strategy as “AES 256-bit on client”.

Backing up Windows-Mapped Drives   

The Zmanda Management Console can back up mapped drives on a Windows client provided the drives have been mapped from the 'amandabackup' account on the Windows machine. This constraint is because few windows server drive letters are not global; different users can map different directories on different servers to the same drive letter. For further information, see the article "Backing up network mapped drives on Windows clients" on Zmanda's Knowledgebase.  

   

Restoring to Windows-Mapped Drives   

The Zmanda Management Console can restore to a mapped drive. The pre-requisites for restoring to a Windows mapped drive are the same as that for backing up the Mapped drive. See the knowledgebase article for requirements.  

You can restore the data backed up from mapped drive to original location or to another mapped drive (alternate location). In ZMC Restore Where page, select the following options:  

Original Location:   Restoring data backed up from mapped drive to original location.  

Alternate Location:  To restore to an alternate location, use the Windows Folder option in the ZMC Restore Where page. Specify the Mapped drive letter or a path in the Mapped drive where the data needs to be restored to. For example, Z:\ or X:\test.  

 

Backing up Windows Applications   

If you have purchased and installed the relevant Zmanda licenses, Amanda Enterprise can perform intelligent backups of selected Windows applications such as Exchange and Oracle. These backups use Microsofts VSS (Volume Shadow Service) to capture a consistent copy of the database(s) in question.  

Refer to the Zmanda Application Module User Guide for further details.  

 

Backing Up Hardlinked Files   

  If only one of the hard linked files is present in the backup set, then the information about its other hard link files will not be backed up. Also at restore time, if only one hard link file is selected for restore, then its other hard link file will not be restored. Please see this Zmanda Knowledgebase Article for details.  

Restoring a Windows Client   

The Restore procedure for a Windows client is similar to the procedure for other clients. You can restore Windows backup image to the Linux/Solaris server. The backup image will be restored as a zip file (ZIP64 format).  

Completing the Restore Where page for Windows Clients   

  Destination Host Type   

 

 

 

 

• You can restore to original Windows client or another machine. If you are restoring to non Windows machine, you will able to restore raw image which will be in ZIP64 format.  
• You can restore to a Windows machine to original location or an alternate location of CIFS share.  
• Click Next to save the changes and move to Restore How page.  

Restoring to Windows-Mapped Drives   

  The Zmanda Management Console can restore to a mapped drive. The pre-requisites for restoring to a Windows mapped drive are the same as that for backing up the Mapped drive. See the knowledgebase article for requirements.  

You can restore to the data backed up from mapped drive to original location or to another mapped drive (alternate location). In ZMC Restore Where page (see the figure in the last section), select the following options:  

Original Location:   Restoring data backed up from mapped drive to original location.  

Alternate Location:  To restore to an alternate location, use the Windows Folder option in the ZMC Restore Where page. Specify the Mapped drive letter or a path in the Mapped drive where the data needs to be restored to. For example, Z:\ or X:\test.  

 

Windows System State Backup and Recovery   

Windows System State refers to a collection of several key operating system elements and their files. Backing up the Windows System State is crucial for a successful disaster recovery strategy. Zmanda Windows Client can back up the Windows System State of all supported Windows platforms. Windows System State is always a full backup (level 0).  

The system state can be restored to the original location or a different location. Partial restoration of Windows System State can be done only to a different directory location. Windows System State files require special handling to back up because they are always locked.  

Restoring a system state backup from one computer to the second computer of a different make, model, or hardware configuration is not supported. See the following Microsoft Knowledgebase article for details:  http://support.microsoft.com/kb/249694  

Depending on the type of Windows system, Zmanda Windows Client software backs up the following System State information in a comprehensive and coherent fashion:  

 

Workstations   

Workstation in this context means any Windows machine which does not have an Active Directory (AD).  

• Boot Files:  

- On Windows XP and Windows 2003: SystemDrive\NTDETECT.COM, SystemDrive\ntldr, SystemDrive\boot.ini(SystemDrive is usually c:).  

-On Vista: SystemRoot\boot directory (SystemRoot is usually c:\windows)  

•  Catalog files: SystemRoot\System32\CatRoot\.                MachineKeys Files: SystemRoot\System32\Microsoft\Protect\* and AllUsersProfile\ApplicationData\Microsoft\Crypto\RSA\MachineKeys\* where ALLUSerProfile is c:\Documents and Settings\All Users.  
•  Performance counters: perf*.dat and perf*.bak files in c:\windows\system32 on all OSs.  
• WFP files: All dll and exe files that come under Windows File Protection (WFP). Usually the dll files reside in c:\windows\system32  
•  IIS metadata file if IIS is installed (applicable to all OSs).  
• Certificate Database (Applicable to only Certificate Servers): files in c:\windows\system32\certsrv  
• COM+ registration database.  
• Registry: System, default, SAM, Security and Software files in SystemRoot\system32\config and additional Components and Schema files.  

Domain Controllers   

  

A Domain Controller (or DC) is any Windows machine with Active Directory installed. DC backups include all of the state information listed above for Workstations, plus the Active Directory database, log files, and Group Policy Objects (GPOs).  

Windows System State Backup from the ZMC   

  

To back up the Windows System State (which is always a full backup), choose Windows System State as the type under File Systems on Sources page of the Zmanda Management Console, and the following options are displayed:  

 

 

 

 

Host Name  The Fully Qualified Domain Name (FQDN) or IP address of the Windows system to be backed up.

Data Deduplication  

Select the checkbox to enable deduplication. Note that user is not allowed to select any encryption and compression

strategies if data deduplication is enabled.  

 

Encryption & Compression Options

Lists Encryption and Compression choices. See Enabling Encryption for Windows Backups for details.  

 

 

Advanced Options - Estimate 

If estimates are taking too long and the databases being backed up do not change in size that much from backup to the

backup, use the Historical Average calculated from previous backups. In most cases, the default of Reliably Accurate is

appropriate.  

  

Backup Set  

Select backupset from dropdown menu to which DLE will be added upon saving.  

  

After you have set the options, click the Save button to add the Windows snapshot to the backup set. You can then configure the backup set just as you would any other by setting the options on Backup Where, Backup How, and Backup When, etc.  

Windows System State Restore from the ZMC   

  

To restore Windows system state, specify the Initial Directory as SystemState in the Restore What page of ZMC.  

Please note the following requirements and cautions regarding System State backup and restores through the Zmanda Windows Client:  

• The System State backup source Windows version, platform (i.e. whether it is 32- or 64-bit) and Service Pack level must match those on the target system. For example, you cannot restore a System State backup taken from windows one version to another, nor can you restore a 32-bit System State backup to a 64-bit target even if the Windows versions match.  
•  If restoring the System State backup to the original source of the backup, you must restore all components of the system state using Restore All option in the ZMC Restore What page; partial restores are possible only to an alternate destination directory.   

  

  

 

 

• Windows Active Directory restores are non-authoritative by default. To perform an authoritative AD and SYSVOL restore, follow the steps here. The Zmanda Windows Client does not directly support authoritative AD/SYSVOL restore.  
• For System State restore to a Domain Controller (provided AD is already installed), you must reboot the machine in Directory Services Restore Mode (DSRM), and then manually start the ZWC Service using the DSRM or "Local System" account, then run the System State restore.  
•  If Active Directory is not installed, then Restoring System State does not require the system to the be in Directory Services Restore boot mode.  
•   Even if the System State restore is not to the original location, the OS versions must match. If the System State that contains the AD database & restore is not to the original location, then the System does not need to be booted in Directory Services Restore mode.  
• While restoring to the entire system state to the original backup source, you must reboot the machine to complete the System State restore.  

Changing the Password for the Amandabackup User   

  

During the installation process, the amandabackup user is created and a password is set. To change the password, shut down the Zmanda Windows Client service, then use the Windows Control Panel utility to edit the amandabackup user account. Use the same procedure as for any other Windows-based password-protected service. Restart the Zmanda Windows Client service when you are done. Note that the service must restart without any errors for the changed password to take effect.  

Please update the amandabackup user password using Zmanda Windows Client Configuration Utility (Advanced options). See the next section.  

Zmanda Windows Client Configuration Utility   

  

The Zmanda Windows Client configuration utility (ZWCConfig) can be used to  

• Create and manage templates  
• Add or remove Amanda servers  
• Change the debug log settings  
• AES 256 bit encryption pass phrase for encryption/decryption of backup images  
• Set advanced options such as the size of the message buffer and location of temporary files  

All Zmanda Windows Client Configuration utility operations have to be performed as Administrator.  

Log on to the workstation as the Administrator and start ZWCConfig utility by clicking Start->Programs->Zmanda Client for Windows->ZWCConfig. Alternatively, you can right-click the menu option to Run as administrator. After you start the program, The Zmanda Windows Configuration dialog is displayed.  

Creating and Managing Windows Templates   

 A Windows template is roughly equivalent to a backup object in the Zmanda Management Console, or a Disk List Entry (DLE) in Amanda. A template is useful if you want to back up different files and folders that reside on different drives as part of a single backup object/DLE.  

 

 

In addition to specifying drives and folders for backup (which can be accomplished via ZWCconfig), you can also manually edit the template file to specify programs or scripts that should run before and after the backup.  

Templates created using ZWCConfig utility are stored in the template.txt file located in the \Misc directory of the Zmanda Windows Client installation directory on Windows XP and Windows 2003 systems, or %ProgramData%\misc in on Windows Vista, Windows 7 and Windows 2008 systems.  

Template Name 

Unique name of the template. Only alphanumeric characters and '_' is 
allowed for a template name.  

Files/folder to include  

List of files and folders to be backed up.  

Add  

Opens a dialog that lets you browse for and select files/folders to back up.  

Delete   

Deletes the currently selected file/ folder from the list of files and folders to include. Click on an entry in the list to select, then click Delete to remove it.  

Templates  

Lists the templates that have been created and saved to template.txt. Use the dropdown menu to select a template to edit, or select <New Template> to create a template.  

Add Template  

Click to add a new template.  

Delete Template  

Click to delete the currently-displayed template from template.txt.  

 

Specifying Scripts to Run Before and After backup and Restore Operations.   

  

You may want to perform automated operations before and after a backup run and/or before and after a restore run, such as deleting temporary files, starting or stopping services, or other such operations that can be performed from a Windows script or batch file. By editing the template.txt file described above, you can specify such scripts to run automatically either before or after a backup run and/or before and after a restore run for a given backup template.  

Simply add a <PRE_BACKUP_SCRIPT> or <POST_BACKUP_SCRIPT> (or <PRE_RESTORE_SCRIPT> or <POST_RESTORE_SCRIPT>) tag(s) to the template.txt file for a given template. The tag's content is the path to script. For example, the following shows what the code would look like to add pre- and post-backup scripts to the MyTemplate template, which backs up c:\data after running c:\preScript.bat (which takes the input file prebackup.txt as an argument), and then runs postScript.bat:  

<MyTemplate>  

        <DLE_NAME>MyData</DLE_NAME>  

        <DLE_TYPE>USER-DEFINED</DLE_TYPE>  

        <FILE_LIST>  

                <FILE_NAME>c:\data</FILE_NAME>  

        </FILE_LIST>  

        <PRE_BACKUP_SCRIPT>C:\preScript.bat prebackup.txt</PRE_BACKUP_SCRIPT>  

        <POST_BACKUP_SCRIPT>C:\postScript.bat  

postbackup.txt</POST_BACKUP_SCRIPT>  

</MyTemplate>  

 
If the pre-backup script fails, the backup returns ZWC_ENG_ERR_PRE_SCRIPT (error code 278). If the pos-tbackup script fails, the error will be logged and backup status will be success.  

If the pre-restore script fails, an error is logged. If the post-restore script fails, the restore returns the appropriate error.  

 

Setting the Amanda Server   

 Click the Server tab to display server settings:  

 

 

 

Server Name  

The Fully Qualified Domain Name (FQDN) of the Amanda Backup server. To specify an IP address instead, you can leave this field blank and use the IP Address field instead.  

  

IP Address  

The IP Address of the Amanda backup server.  To specify an FQDN, you can leave this field blank and use the Server Name field instead.  

  

Server List  

This drop-down menu lists previously-saved Server Names that you can select for viewing and changing settings.  

  

Add/ Delete Server  

Lets you save the current Server Name (along with its settings) to the Server list dropdown.  

Click Exit to save any changes you have made and exit the ZWCconfig utility.  

Changing the Log Settings   

[Text Wrapping Break]  

Click the Logging tab to display log settings:  

 

 

Log File Location  

Log file will be stored in the \Debug subdirectory of the Zmanda Windows Client Installation directory by default.   

  

Log Level  

Range of 1-5. Increasing the level generates more detailed logs; decreasing the level results in more compact (but less detailed) logs. The default level is 2.  

  

Log File Size (in MB)  

Depending on the Log Overwrite setting (see below), when this file size limit is reached, the log file will either be renamed to NLogFileNumber.txt (allowing more recent information to be saved in LogFile.txt) or simply overwritten with newer information. If log rotation is enabled, older files are overwritten after the Log File Count is reached.  

  

Log File Count  

When log rotation is enabled (i.e., Log Overwrite is disabled), sets the number of logfiles that can be saved before older files are overwritten with newer log entries.  

  

Log Overwrite  

If checked, disables the rotating log feature (in other words, newer log entries will overwrite older entries in LogFile.txt after Log File Size has been reached).  

  

Save 

Saves the log settings currently displayed.  

  

Reset  

Resets all log settings to their default values.  

  

Exit  

Exit the ZWCconfig utility.  

 

Advanced Settings   

 

 

 

Data Queue Size  

Set the number of buffers allowed within each queue of the ZWC messaging framework. Do not change from the default of 50 unless a different value is recommended by the Zmanda Support Team.  

Temporary Directory  

Sets the location of temporary files created during backup and restore processes. For Windows Vista, the default is C:\ProgramData\Zmanda; for other Windows platforms it is the \Misc subdirectory of the ZWC installation.  

Backup Port/ Restore Port  
Ports to use for backup of and restore to the Windows client.  

Encryption AES Key  

Sets the encryption passphrase to use when AES 256 bit encryption is chosen while taking backup. The encryption passphrase is set for each Windows machine. All backups done on the Windows machine are encrypted using the same key as long as AES 256 bit client encryption is configured on the ZMC.   

Zmanda Windows Client does not manage keys. Customers must backup encryption keys separately.   

Password for user amandabackup 
Update amandabackup user password if it has been changed since Zmanda Windows   

Client installation.  

Save  

Saves the advanced settings currently displayed.  

Reset  

Resets all advanced settings to their default values.  

Exit  

Exit the ZWCconfig utility.  

When you exit the program, you are prompted to restart the ZWCservice, which is necessary for the configuration changes to take effect.  

The Zmanda Windows client service can also be manually restarted from the Windows services user interface (Administrative Tools > Services). An example services screen is shown below.  

 

 

 

 

Exporting and Importing Key container   

  

Zmanda Key Container is required only if you have backup archives client encrypted using ZWC 3.6 release.  

Encryption Metadata for the association between amandabackup user and the digital certificate used is stored under the Zmanda key container on disk on the backup client machine.It is important to export the key container before uninstalling ZWC on the client machine. Also, this key container will be needed, in the case of restoring encrypted archives on a different  machine.  

 
The exported XML file is needed for disaster recovery and must be backed up. To export and import key containers, .NET framework (version 2.0 or greater) must be installed on the Windows machine. It is usually found under C:\WINDOWS\Microsoft.NET\Framework and Framework64 folders.  

 
To export the Zmanda key container to XML file, run the following command (Windows Start > Run > command):  

aspnet_regiis -px “Zmanda” “<Name of XML file to be created>” -pri  

IMPORTANT: Before importing Zmanda key container from another machine, make sure you have exported Zmanda key container from the current machine. This step is necessary if you are importing Zmanda Key container to a machine that is already performing Amanda encrypted backups. Use the above procedure to export Zmanda key container. To import the Zmanda key container from the XML file, run the following command (Windows Start > Run > command):  

aspnet_regiis -pi “Zmanda” “<Name of the exported XML file>” -exp  

You will need to import the exported key container from the current machine, in order to recover from encrypted archives backed up from this machine.  

After importing the Zmanda key container, the digital encryption certificates have to be imported for the amandabackupuser. This is necessary to recover from encrypted archives.  

Compatibility with Previous Versions of the Zmanda Windows Client   

  

If you have created backup images using Amanda Enterprise edition Windows Client 2.6.1 or older,  the older version of the client is required to recover the files to a Windows machine. Contact the Zmanda Support team for assistance. Alternatively, you can use the current version of Amanda Enterprise to recover the files to the backup server and then move them manually to the client.  

Running the Windows Client Support Script   

  

The zwc-support utility collects system log files, log files related to ZWC and system related information. The utility then archives these log files into a single compressed file.You must run the utility as the Administrator. This compressed file can be then sent to the Zmanda Support team for analysis.  

Location   

  

The Zmanda Windows Client support utility zwc-support.bat is included with the Zmanda Windows Client. To start the script, click Start->Programs->Zmanda Client for Windows->zwc-support
