To troubleshoot an SMSQL backup problem, we have removed the SnapMirror kickoff flag from several SnapManager for SQL backup jobs and replaced them with manually scheduled SnapMirror jobs. Now that a few days have passed, I've noticed space is low on many of our volumes, and there are two old @SNAPMIRROR snapshots (outside of our retention window) on each volume where we made this change. Can these snapshots safely be deleted? I believe these are just the snapshots used by SMSQL to manage the SnapMirror process. We still have a snapmirror snapshot that is up to date on each of these volumes. Any thoughts or suggestions?
