Repair old retention snapshot

Hi all. Can you tell me if it is possible to restore snapshots that have been deleted? maybe the service hasn’t cleared their data yet? Thank you

Sounds like a very small chance. First of all, the snapshots are basically long list of pointers into the blobs of data, so if a snapshot is lost (for whatever reason), then you don’t know what this list should be, and hence can’t really re-create it. The individual piece of data is not pointing backwards to all the snaps that point to it.
