PowerProtect Data Manager 19.16 File System User Guide

• DFS metadata (DFS namespace)
• DFS user data (user data share linked to DFS links)

Depending on the DFS configuration type (stand-alone or domain-based DFS), DFS stores its metadata in various locations such as registry, active directory, and so on.

BMR backup

If DFS links and DFS user data share are part of critical volumes, BMR backups them. See Critical volumes in disaster recovery for more information.

BMR restore

If DFS links and DFS user data are part of critical volumes, by default, BMR restores them including all the DFS metadata.

SSR backup

SSR backups only the DFS configuration data but not the DFS user data.

SSR restore

Always perform the full system state restore to fetch the DFS metadata information. If the DFS machine is a domain-based appliance, perform the full system state restore followed by AD authoritative restore.

NOTE:Performing full system state restore helps in completing the restore process even when DFS service files are corrupted.

To protect DFS user data,

• Use File System agent to protect user data.
• If the user data is present on NAS share, use NAS agent to protect it.
• If the user data is part DFS other than File System or NAS agents, use the respective agent to protect it.
