Consider the following when preparing for asset-level backups:
• | Maximum file pathname lengths |
• | Default exclusions for asset-level backups |
• | Exclude active databases from asset-level backups |
• | Mac OS X Sleep Mode |
For some Unitrends agents, there is a maximum file pathname size limitation. File pathnames that
exceed this limit are not included in the backup. Agents affected by this restriction and supported
maximum file pathname lengths are noted in the following table.
Unitrends agent |
Maximum file pathname length |
Windows |
32 KB |
Linux |
4 KB |
Solaris |
1 KB |
Mac OS X |

By default, certain files and directories are excluded from asset-level backups of Windows and Linux assets. For details, see the following topics:
By default, certain directories and files are excluded from asset-level backups of Windows severs. These exclusions are in addition to any exclusions you have applied to the Windows server’s backups.

• | 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 |

By default, certain directories and files are excluded from file-level backups of Linux. 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 all active databases from asset-level backups. Run application-level backups to protect active databases. For information on application backups, see Application Backups Overview.
Some active databases are automatically excluded with asset-level backups, as described here:
• | Exchange — All transaction log files (i.e., .LOG files), the Exchange database (i.e., .EDB files), and streaming content files (i.e., .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.
