Consider the following information when preparing for asset-level backups:
Some Unitrends agents have a maximum file pathname size limitation. The backup does not include file pathnames that exceed this limit. The following table lists the agents affected by this restriction and the supported maximum file pathname lengths.
Unitrends agent |
Maximum file pathname length |
---|---|
Windows |
32 KB |
Linux |
4 KB |
Solaris |
1 KB |
Mac OS X |
1 KB |
By default, asset-level backups of Windows severs exclude certain directories and files. These exclusions are in addition to any exclusions you have applied to the Windows server’s backups.
By default, file-level backups of Windows servers exclude:
• | Any mapped network drives |
• | /RECYCLER |
• | /$Recycle.Bin |
• | %TMP% |
• | %TEMP% |
• | *.tmp |
• | *.temp |
• | %AllUsersProfile%\Microsoft\Network\Downloader\Cache |
• | %WINDIR%\System32\Config |
• | %WINDIR%\System32\Catroot2 |
• | %WINDIR%\win386.swp |
• | Contents of the server’s DataDirectory as specified by the registry key HKLM\Software\Microsoft\Windows |
• | Contents of the server’s DefaultDataDirectory as specified by the registry key HKLM\Software\Microsoft\Windows |
• | Files specified by the registry key HKLM\System\CurrentControlSet\Control\BackupRestore\FilesNotToBackup |
• | Additionally, the following profile directories specified by the registry key HKLM\Software\Microsoft\WindowsNT\CurrentVersion\ProfileList\*\ProfileImagePath\ are also excluded: |
– | \AppData\Local\Temp |
– | \Local Settings\Temp |
– | \Local Settings\Temporary Internet Files |
By default, file-level backups of Linux exclude certain directories and files. These exclusions are in addition to any exclusions you have applied to the Linux client’s backups.
Note: If you need to include any of the system-excluded directories in your environment, see KB 2781.
Default Linux directories excluded from backup:
• | Any network mounts |
• | /proc |
• | /sys |
• | /var/tmp |
• | /home/*/.gvfs |
• | /var/lib/nfs |
• | /rpc_pipefs |
• | /lib/modules/*/volatile/* |
• | /usr/bp/incremental_forever |
Unitrends recommends excluding active databases from asset-level backups. Run application-level backups to protect active databases. For information on application backups, see Application Backups Overview.
Note: SQL files for system databases (such as master, model, and msdb) are always included to support the Windows instant recovery (WIR) feature. Do not exclude these if you will be using WIR for hosted SQL databases.
Some active databases are automatically excluded with asset-level backups, as described here:
• | Exchange — All transaction log files (.LOG files), the Exchange database (.EDB files), and streaming content files (.STM files) are excluded. See Automatic exclusion of application data during asset-level backups. |
• | SQL — The following extensions are excluded from SQL user databases if the SQL VSS component is running on the Windows asset: .mdf, .ldf, and .ndf. Files in SQL database/log directories are excluded. See Automatic exclusion of SQL data during asset-level backups. |
Either disable or configure the Mac OS X Sleep Mode to accommodate scheduled backups.
