ReadyNAS 312 Need Help Understanding Snapshots
We're about to pull the trigger on a ReadyNAS 312 with either two 2TB or 4TB drives. We have about 290GB of data files. Ideally we'd like to have daily snapshots, but I'm unsure how much data a snaps...
Yes. In your case, you'd see all versions captured in your hourly snapshots. (Not sure, but I think you won't see duplicates, just distinct versions).

If a file was changed twice between snapshots, you'd miss a version.
BTW the automatic snapshots are pruned back. Hourly snapshots are kept for 48 hours, daily snapshots are kept for 4 weeks, weekly snapshots are kept for 8 weeks, and monthly snapshots are kept indefinitely. That will also thin the available versions over time.
