SOLVED Snapshots - specific time

[tiberiusQ]

Dear all,

Super quick question just to get sure- In addition to my hourly snapshots I wanna setup daily snapshots at a specific time for example everyday at 08:00 so the >>> begin and end both at 08:00 ?
Sorry for that odd question but the begin and end description is confusing me.

Thx & Best,
T.

yes, however, setting it to 0 minutes available time might make it never happen.
also, if something causes a snap during that time period to not occur i think it will just never happen.
what purpose is there for limiting it instead of letting it work the way its designed? sounds like micromanaging for no reason tbh.

The time settings are just for choosing at what times snapshots can happen. The snapshots themselves are instantaneous.

It's been at least a day since I've mentioned my own solution to this issue, so I'll direct you to ZFS Rollup: https://forums.freenas.org/index.ph...napshots-similar-to-apples-timemachine.10304/

Set a single frequently recurring snapshot schedule, with a long retention time, and let the script prune the excess over time.

If I understand u guys right- I can do that to schedule snapshots begin eg. 08:00 and end 08:30 but the snapshot will then created at 08:00 ?

Setting the begin and end snapshot time both at 08:00 is a bad idea ?

Probably.
