Fast restore here will have negative consequences as shown in analysis. You are trying to do the fast restore from a snapshot which is older than the baseline snapshot of the snapmirror relationship. The relationship to the secondary will be broken if you do so and backups will not get protected to snapmirror destination.
Fast restores should always be used with caution.
You should either restore from a backup created after the relationship's baseline snapshot or break the relationship manually, and then recreate, rebaseline the relationship after the restore.
Thank you for your answer. My Storage Admin tell's me that we have a policy in SnapMirror which copies all changes on Primary Storge to Secondary in a 5 Min. interval. So 5 Min. after the backup is taken it is useles for fast restore.
Is there a way I can break the relationship from SMO ? As a DBA I don't have permission to use root user or a snapmirror account outside from SMO.
Can someone point me to a whitepaper or could describe how the Backup/Restore/Clone is handled in a SMO/SnapMirror Environment with large DB's (2TB +).
Re: Fast restore not possible because of SnapMirror
You can override the SnapMirror baseline snapshot copies check only if SnapDrive for UNIX Role based access control (RBAC) is configured with operations manager, and as a user you have the SD.SnapShot.DisruptBaseline capability assigned by the operations manager administrator. This is not possible without enabling RBAC,
If there is no DFM integration involved, then storage admin manually has to break the relationship and after the restore, recreate the relationship.
