Question
An administrator is reviewing backup jobs and notices that backups of VMware VMs that are located on a SAN are taking longer than normal to back up. What could be a cause of this?
A. The backup proxy in use is failing over to Virtual Appliance mode.
B. The guest interaction proxy is failing over to data access mode.
C. The backup proxy in use is failing over to Network mode.
D. The backup repository needs to be changed to a Scale-out Backup Repository.
Answer
C. The backup proxy in use is failing over to Network mode.
Explanation
The most likely cause of the slow VMware VM backups located on a SAN is that the backup proxy in use is failing over to Network mode (Option C).
When a backup proxy fails over to Network mode, it no longer has direct access to the VM data on the SAN. Instead, it must retrieve the data over the network from the ESXi host, which can significantly impact backup performance. This failover typically occurs when the backup proxy loses its direct SAN connection or encounters issues with the SAN storage.
The other options are less likely to be the cause:
A. Virtual Appliance mode is not related to backup proxy failover.
B. Guest interaction proxy failover to data access mode is not directly related to backup performance.
D. Changing the backup repository to a Scale-out Backup Repository would not address the root cause of the slow backups, which is the backup proxy failover to Network mode.
To resolve this issue, the administrator should investigate the reasons for the backup proxy failover and work on restoring the direct SAN connection for optimal backup performance.
