RN214 OS6.10.10 Snapshots

I analysed the NAS status.log and found the NAS simply starts deleting snapshots for no apparent reason!

Some snapshots have been present for >600 days. I have attached a file which shows every snapshot created/deleted, along with some stats like how old it made it. I also tried to attach the original log file, but this forum wouldn't accept (maybe size of post?). Some points:

• Snapshot #11
  • created 2023-10-30, deleted 2025-07-05, age 614 days
• Snapshot #120:
  • Created 2025-08-17, deleted 2026-04-25, age 275 days
• Both times, snapshots were completly removed over a period of a few weeks

I am open to sharing any more info to help better understand what is going on, but right now I'm thinking smart snapshot manageent is too random to be reliable.

Processed file showing snapshot history/info (it seems I can't insert the whole file, so here are some snips):

Column summary:
