Also in case where the application and backup systems are the same,
ensure that the VSS/VDS hardware provider is configured for the same
Command View on both EVAs. Otherwise, rotation and deletion of old
replicas from other EVA cannot be performed.
Note that if a failover of the production and copy databases happens, the
backup using the same backup specification as before failover will fail,
since the backup system is no longer connected to the disk array where
the new replicas reside. In this case, you can:
• Perform manual failover of the production and copy databases to
enable the same configuration as before the first failover.
• Create a new backup specification with the new backup objects
specified.
• Change the backup system connection to the disk array where the
new replicas reside.
For restore limitation of this scenario, see “Limitations” on page 60.
