The backupVapp and restoreVapp commands will backup configuration files, custom configuration files, UserStore and Provisioning Directory data running on CA Directory on the VApp nodes. This includes IP address and system-specific information. Any external databases would need to be backed up separately.
Question: If there are multiple nodes, can the backup from running backupVapp on one node be used to restore on another?
The backupVapp command should be run individually on each node, and only its output should be used with restoreVapp for that node. This will avoid errors such as incorrect IP addresses etc.
