Catalog backup policy may fail or use the remote media server for backup

When disaster recovery is configured, the catalog backup policy is configured with the storage unit that is local to the cluster. After migration, it is possible that the catalog backup policy is configured with the storage unit on the remote site and in such cases, the media server present on the remote site is used for catalog backup. After takeover, the catalog backup can fail as the catalog backup policy is configured to use the storage unit on the remote site which was not available at the time of backup. (IA-30251)

Workaround:

It is recommended that SLPs should be used for catalog backup policy in disaster recovery configuration and catalog backup policy should be updated with reverse SLPs after migration or takeover process.
