ZFS recursiv snapshot rollback

I’m using zfs snapshots to save all non global zones filesystems via cron. This can be achieved using the zfs snapshot option “-r”. During snapshot creation this means

create snapshots on the target filesystem and all descendants filesystems

If made a mistake and you want to rollback the last action you will be disappointed that the corresponding “-r” option of the zfs rollback command has a different meaning:

destroy snapshots newer than the specified snapshot

All posts in the internet that I found show that there is no way to make a recursiv rollback with just using zfs. A small shell script can help to make recursiv rollbacks:

zfs-recursive-rollback

Of course you have to make the file executable after copying it to your system with a command like

You should also adapt the command line options in the script to your needs if the options in the script do not fit.

  1. Thanks for the script. Doesn’t make sense to me why there isn’t an option to do this. I’d imagine a full rollback is fairly common usage.

  2. Thank you very much for the script! Saved me a lot of work. I’m also surprised that there wasn’t a option to do so.
