Dell NetWorker 19.9 Administration Guide

WINDOWS ROLES AND FEATURES save set

The WINDOWS ROLES AND FEATURES save set was introduced in NetWorker 8.1 and replaces the VSS SYSTEM BOOT, VSS SYSTEM FILESET and VSS SYSTEM SERVICES save sets. The DISASTER_RECOVERY:\ save set contains the WINDOWS ROLES AND FEATURES save set as a component save set.

The WINDOWS ROLES AND FEATURES save set contains:

• Data that are associated with the roles and features that are installed on the Windows server.
• Metadata that represents the volume data which the ALL or DISASTER_RECOVERY:\ save set backs up.

Before backing up the WINDOWS ROLES AND FEATURES save set, consider the following:

• Block Based Backups (BBB) do not support the WINDOWS ROLES AND FEATURES save set.
• You cannot restore the WINDOWS ROLES AND FEATURES save set simultaneously with data from a file system backup. If you must recover data from both the WINDOWS ROLES AND FEATURES backup and a file system backup, restore the file system data first, and then restore the WINDOWS ROLES AND FEATURES data.
• The NetWorker software automatically backs up AD as a component of the WINDOWS ROLES AND FEATURES save sets. An AD backup or restore includes the AD log files, database, patch files, and expiry token.
• You can perform an online recovery of the WINDOWS ROLES AND FEATURES save set to recover the Active Directory, DFSR, or Windows Server Failover Cluster services. The topic Online recovery of Active Directory, DFSR, or Cluster service provides more information.
• If you cancel a deduplication recovery, the state of the recovered data is not reliable and may contain corrupted data. To ensure that the recovery is correct, restart the deduplication recovery process.
• The backup operation only confirms that the VSS System Writer exists on the target host. If the backup operation does not detect the writer, the backup of the DISASTER_RECOVERY:\ or ALL save set fails. The backup operation does not track and report any other missing VSS writers.
• You can perform a component level granular restore of the WINDOWS ROLES AND FEATURES save set with a command line recover or the NetWorker User application. For example, you can recover the system state and replication folders separately. You cannot use the NMC Recovery UI to perform a component level restore.
• Do not restore the WINDOWS ROLES AND FEATURES system state multiple times in succession without restarting the computer as required. If you do not restart the computer, you can put the system in an unreliable operational state.
