This page describes the environmental requirements you should verify before running the install program. The Amanda Enterprise Edition components required on each are described in /p/span, line 1, column 23: ")" expected.
Throughout this document, The Amanda Client refers the system being backed up by the Amanda Enterprise Edition Server, which also called the Amanda Server or backup server.
- Identify the hosts and filesystems to be protected using Amanda software. The list of hosts to be protected are the Amanda backup clients. The Amanda backup clients and the filesystems or directories to be backed up on each client will need to be specified during Amanda configuration.
- Identify the Amanda backup server. The Amanda backup server should have access to the media (tape, disk, changers) where the Amanda client backups will be stored. Any Amanda client can also act as an Amanda server, and it is recommended that every Amanda server also be a backup client. In selecting your Amanda backup server machine, keep in mind that the server might use a significant amount of memory during backup runs, and that it must have good network connectivity to all Amanda clients.
Amanda Enterprise Edition backup server requirements
- The Amanda server and clients must have the latest service packs or updates to the distribution installed.
- Amanda server and client cannot be installed on an NFS-mounted file systems.
- To run the Rapid Installer, the Amanda Server requires 256MB of free memory. You should have at least 500MB of disk space, and you should not install the ZMC itself (/opt/zmanda/amanda) on an NFS partition.
- In addition to the space required for the software itself, you should ensure that there is always 10% free in the Zmanda installation and temporary directories. If Amanda Enterprise Edition runs out of space on either of these directories while a backup is in progress, the backup will fail with MySQL errors similar to the following:
System Error
DBD::mysql::db do failed: Incorrect key file for table
'/var/tmp/#sql_24b8_0.MYI'; try to repair it at
/opt/zmanda/zmc/bin/amreport_wrapper line 105.
8:51:26, Mon Mar 17, 2008:ZMC Database Query failed: mysql query
failed:Incorrect key file for table '/var/tmp/#sql_24b8_0.MYI'; try to repair it
- If you encounter messages like this, try increasing the amount of available disk space in the relevant directories.
- The Amanda server and client require that certain communication ports are open:
- The Amanda server must open inbound TCP ports 11000:11040.
- Non-Windows Amanda clients must open inbound TCP port 10080 and outbound TCP ports 11000:11040.
- Windows clients must open inbound TCP ports 10080 and 10081, and outbound TCP ports 700:800.
Backup Server Package Dependencies
The following packages are required on the ZRM Server (32-bit versions of packages required):
Linux
- compat-libstdc++-33-3: The GNU C and GNU C++ Compiler runtime libraries
These packages are installed by default on most Linux distributions. If you need to add them, you can use yum or apt-get, either from the distribution media, or from a distribution repository (run either as root):
#yum install package_name
or
#apt-get install package_name
Solaris 10 (Both Sparc and Intel Architectures)
- perl
- mailx: The mailx package can be found as part of the OS distribution. The mailx package must be configured to send mail from the ZRM machine to the MySQL database backup administrator.
- gcc3g++rt: The GNU C++ Compiler runtime libraries
- CSWgcc3corert: The GNU C Compiler runtime libraries
The Zmanda Network downloads page collects all of these packages in a downloadable tar archive (which is made available after you select a platform to download). If necessary, download the tar archive to the local system, extract it, and run pkgadd as the superuser to install it:
# pkgadd -d package_name
Backup/restore client requirements
For restores to work through the ZMC, the client (regardless of platform) must keep TCP port 10081 available for the Zmanda recovery process. Refer to your OS network configuration documentation for details on opening ports for applications.
Package dependencies for Backup Clients
Amanda Enterprise Edition requires the 32-bit versions of all packages.
Linux
- perl
These programs are installed by default on most Linux distributions. If you need to add them, you can use yum or apt-get to install them, either from the distribution media, or from a distribution repository (you run either as root):
#yum install package_name
or
#apt-get install package_name
Solaris 10 (both Sparc and Intel Architectures)
- perl
- SUNWcsu
- SUNWsshcu
- SUNWgzip
- SMCtar (version 1.15.1 or greater)
- SMCgpgme
- SMCgrep
- SMCcoreu
The Zmanda Network downloads page collects all of these packages in a downloadable tar archive (which is made available after you select a platform to download). If necessary, download the tar archive to the local system, extract it, and run pkgadd as the superuser to install it:
# pkgadd -d package_name
Windows (2003 Server, XP, and Vista)
Windows clients must open inbound TCP ports 10080 and 10081, and outbound TCP ports 700:800. Windows application backup (licensed separately) requires that the Volume Shadow Copy Service be enabled and started. See the The Zmanda Client for Windows User's Manual for details.
