zfs-auto-snapshot VS znapzend

From my research, I can see two options: - Proxmox specific cv4pve-autosnap - generic zfs-auto-snapshot, available in repos

Since Proxmox natively supports ZFS, you could that to make your snapshots. You can do automatic snapshots with zfs-auto-snapshot or for VMs with cv4pve-autosnap.

If you're using zfs-auto-snapshot (and it looks like you are), note that the timestamps are always in UTC, not your local timezone. Is your timezone somewhere around UTC-12:00?

You may want to skip trying to manage these manually and use something like this: https://github.com/zfsonlinux/zfs-auto-snapshot

Not every operation, but it's easily automated. https://github.com/zfsonlinux/zfs-auto-snapshot

zfs-auto-snapshot is as simple as it comes. It has cron jobs that show you how to take periodic snapshots. It cleans up its old versions.

Another option to look at (again, 3rd part stuff, not vanilla zfs hold/release stuff) is zfs-auto-snapshot which takes (and retains) n snapshots based on how you run it. See: https://github.com/zfsonlinux/zfs-auto-snapshot

I have rather nice experience with ZnapZend https://www.znapzend.org/

Only issue i've found is the fact there is no official Debian repository and i always do forget to recompile it after upgrading Debian :-D

I really like the configuration system integrated in ZFS set/get...

Hi, I'm using zfs on my home server since years. (Proxmox host). Never had any problems, I'm using https://www.znapzend.org/ for automatic snapshot which are cheap (time and required space) and they get synced with my backup server.

If you need something that’s more for peace of mind than for rigorous backup policy, you could use the ZFS storage driver, and do periodic snapshots of the whole tree, or use some shell scripting to enumerate the volumes you care about and zfs snapshot or zfs send them somewhere safe.

znapzend is a perl application for snapping, sending, and receiving.

The official documentation is overly complicated for this purpose. A simple example config is:

OK question time! I have znapzend configured via znapzendzetup. Now need to set up a matching OpenIndiana service as described here.
