We have Snapcenter setup to backup a MSSQL instance. There is one backup that we want to keep longer than the normal retention period. Is there any way to mark the backup as a 'keep longer'. The reason is, there were major changes to a test database and we've been asked to restore that test database a couple times already. We don't want the snapshot to be deleted at the end of the retention period until it's owners say all is good and then we can delete.
