ReadyNAS 312 Need Help Understanding Snapshots

Oh, I mean we will no longer be in a server environment once we go to ReadyNAS. Just too few people to justify the added expense and overhead.

Ok.

But your users will still be able to right-click on a file in windows explorer and select "Previous Versions" just like they do now.

Wait...Really? I thought that was server based the whole time! So, if I have a share on my NAS called Data that is mapped as the J drive, a user can right click it still and see previous versions?

Yes as long as snapshots are on for the share.

That's very cool! So the NAS just takes on the added space for storing the previous versions huh?

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.

This is very cool!!! Thanks again for your help. Very much appreciated.

If the usage on the volume exceeds 95% the oldest automatic snapshots will be removed to get the volume usage back below 95%.

Yes, I forgot to mention that.

It's much better not to let the NAS get that full of course.

ALL snapshots are visible, NOT just distinct versions.

I believe that the automatic monthly snapshots MAY be deleted, when the discs get full, default 95% alterable via the shell.
However the manual snapshots are NEVER deleted, except by you of course.

EDIT:- Sorry guys ... started reply before lunch and continued after, resulting in duplication (the second point).
The first point still stands and is new to the post .......All snapshots are visible.

The threshold is alterable using the shell not via the UI.
