Let's say I have a NFS volume, and with FabricPool and snapshots policy enabled. The minimum cooling days are 2 days, which means any cold BLOCKS have not being modified will be tiered to S3 bucket. The snapshot policy is set to one per day.
Let's also assume that the volume got corrupted or infected (encrypted) by ransomware on Friday, can I then use snapshot taken Thursday, Wednesday, or any day before Friday to restore data?
My answer probably not, because the metadata or the active data may be got corrupted, It is not necessary that all blocks involved for that day I need would be tiered to S3, then I can not restore all blocks back. FabricPool with Snapshots policy is not backup. Am I right?
Can experts here please confirm or shed some light for me?
