Enable optimized backup of Windows deduplicated volumes
Select this attribute to enable optimized backups of optimized files on a Microsoft Data Deduplication file system.
If a client has a Microsoft Data Deduplication file system configured, NetBackup performs an optimized backup of optimized files. (Unoptimized files are backed up as full, intact files.) If the client does not have a Microsoft Data Deduplication file system, a normal file backup occurs.
If you do not select this option, NetBackup still backs up the files but does so as intact files: the files are fully reconstructed and backed up as complete files. An unoptimized backup of optimized files is not efficient: it takes extra time and extra disk activity to reconstruct each file. However, restores are faster because NetBackup does not reconstruct the files (restores are unoptimized regardless of the type of backup).
Note:
For easier management, Veritas recommends creating a separate policy to back up deduplicated volumes.
Only full backups are optimized. Incremental and user backups are backed up as full, intact files.
This option is supported on the Microsoft operating systems that support Data Deduplication file systems. For supported Microsoft operating systems, see the Microsoft documentation.
