We are planing hourly snapmirror update from source filer FAS2040 (DC) to destination filer FAS2040 (DR) for a volume.
Our query is below.
Suppose at 11.45 AM , we come to know that there was file corruption at source (DC) and it happened at 10.30 am . Can we revert backup to status at 10.00 am by using reverse snapmirror resyncs from DR to DC ?
If yes, What is the procedure ?
Can we achive this by deleting snapmirror snapshot of 11.00 am from both DC and DR?
VSM is exact mirror of source anyway. So if you update every hour, at 11:00 you will have the same corruption dated 10:30 on destination too. You can simply revert to snapshot earlier than 10:30 on source as long as you still have it.
VSM is not really intended for such sort of things. To protect against logical corruption local snapshots are just fine.
