zfs_autobackup VS zfsbud

I recommend you to get familiar with https://github.com/psy0rz/zfs_autobackup/wiki first and then use the configuration you are happy with in my script.

I have a small home server running Ubuntu Server with a ZFS file system. To back up my files and use snapshots, I am currently using zfs-autobackup, which is easy to set up and works really well for ZFS. However, zfs-autobackup does not provide any information on files or folders that have been created, updated, or deleted from previous backups. While I am not too concerned about newly created or updated files, I would like to know which files have been deleted compared to the previous backup. Ideally, I would like to be able to see which files have been deleted before the backup takes place, so I can recover any unwanted deletions before it's too late.

as described here https://github.com/psy0rz/zfs_autobackup/issues/170

Use ZFS Autobackup https://github.com/psy0rz/zfs_autobackup or ZFS send and receive to create a clone of an existing pool on a new system https://www.thegeekdiary.com/zfs-tutorials-creating-zfs-snapshot-and-clones/

I just went back to sanoid. I have also looked at zfs-autobackup and might give that a try. I've been combining sanoid/syncoid with this script to clean up snapshots

If you want it to work really well in all circumstances, it WILL get complex. I tried to keep the code as readable as i could though. There where many refactors. Check it out: https://github.com/psy0rz/zfs_autobackup

Also have a look at https://github.com/psy0rz/zfs_autobackup .

You will probably need to list the destination snapshots and pick the last one in a shell script and if you are not game, you can use something simple like zfsbud to do the work for you.

A simple bash-only alternative with a configuration file is zfsbud maintained by me.
