Toasters --
Having abandoned synch SnapMirror due to compatibility issues, we are looking to asynch snaps for BCP/DR. Unfortunately we still need to cut the SnapMirror destination (7.2.4) to tape via NDMP. It looks like an outstanding bug http://now.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=36554 and corresponding KB article http://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb44293 indicate that the schedules of SnapMirror and NDMP moves should never compete with one another due to tripping on one another's snaps.
So we either need to
1.) break the mirror in order to blow out backups, or 2.) setup a SnapMirror schedule which leaves a window for scheduled backups.
$mgmt would much prefer the first option in order to maximize replication, and since no one is able to confirm test numbers for backup time duration. So ... any production tips on hailing the SnapMirror destination to break when its time to get our NDMP on? And resync'ing upon NDMP completion? Or am I really off-base with the above? :)
Insight appreciated. Thanks.
