When Amanda is configured and licensed for MS Sharepoint backup, Amanda uses the Microsoft Windows Volume Shadow Copy Service (VSS) to back up the Sharepoint databases and logs.
ZWC backs up and restores MS Sharepoint at database level. ZWC backs up sharepoint data that is stored in the SQL database, such as
Just as with any other type of Windows file system, the ZWC perform performs incremental backups of databases and transaction log files based on modification time. The ZWC does not support transaction log based backup.
Other files (such as the Sharepoint installation directory, IIS metabase information) require separate backup set configuration for backup.
ZWC currently supports only single server farm (standalone) configuration. In other words, the front-end server and the database server must reside on the same machine.
These instructions assume you have already installed and licensed the Amanda Enterprise server, Zmanda Windows Client, and the Sharepoint Server being backed up. Because the Volume Shadow Copy Service (VSS) takes care of any necessary file locking and transaction log pruning during the backup process, the remaining requirements are simple: :
Windows Sharepoint Servcies VSS Writer service must run under the admin app pool account, which is the Network Service account in a basic installation of Windows SharePoint Services.
The Zmanda Client for Windows uses snapshots for Sharepoint server backups. The procedure described below only backs up the Sharepoint database mentioned above.
Create a dedicated backup set for each Microsoft Sharepoint Server you intend to back up. On the Backup What page you are prompted to select what type of object you want to back up. Choose Microsoft Sharepoint, and the following options are displayed:
After you have set the options, click Add. Depending on the Mode of Operation (Planned or Live) the changes are added to the list and/or actually made live on the server; 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.
Make sure that MS Sharepoint is installed in the same location as when the backup was run. The databases and logs file locations should also match the original configuration. When you have selected the disk list entry that includes the Sharepoint databases for restore, the Restore What page displays a dialog that lets you specify what to restore.
Select all the host databases and log files on the Restore->What page.
Server loss can be caused by software or hardware failure, or by the physical loss of the site where the server was housed. Disaster recovery operations are performed only when a fatal disaster occurs,which usually involves replacement of hardware and sometimes re-installation and setup of software.
One would also need to recover Sharepoint databases in case of issues such as database corruption, loss of transaction logs, accidental deletion of web applications, etc.
Sharepoint databases can be restored to the same server or to an alternate server depending on the Recovery plan decided by the Administrator.
When you have selected the disk list entry that includes the Sharepoint databases for restore, the Restore What page displays a dialog that lets you specify what to restore.
Select the host database/s and log file/s on the Restore->What page which needs to be restored.
On restore->where page select the target server. If restore is to be done at original location, leave the destination directory blank.
Requirements for restoring sharepoint database/s to original location on same or alternate server
Note: If the configuration database and Central Administration content database are backuped using the built in sharepoint backup and restore feature, restoring backups of the configuration database and Central Administration
content database taken from a running farm is not supported (http://technet.microsoft.com/en-us/library/cc261903.aspx#section5).
In contrast as ZWC uses VSS for backup and restore for sharepoint, such limitation do not apply. One can easily take a backup of entire sharepoint farm including admin and config databases while sharepoint services are running and then safely restore them without any problems.
