zfs_autobackup VS sanoid

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 .

I’m on the other end of the spectrum. I like knowing the flags and settings I use to create the pools.

For snapshots and replication take a look at sanoid (https://github.com/jimsalterjrs/sanoid).

I use a combo of PBS and ZFS with Sanoid. The ZFS snapshots are nice because you define it all in a config file with frequent, hourly, daily, weekly, monthly snaps retained however you want. Importantly I use that on the root pool as well as my data pools. With PBS I have a custom retention config and have it backing up VMs and LXCs every couple hours. The PBS dedupe functionality makes it possible to keep full backups going back ages with minimal storage consumption, just the changed blocks. PBS is running inside a VM yes, but it’s storage is on another pool.

No, it's written by the developer of Sanoid and Syncoid. The foremost open source ZFS snapshotting tool. He contributes on this sub all the time.

Hi there! Not so much to answer your questions, but are you aware of Sanoid and syncoid? It does backup and remote Sync in the most seamless way. Perhaps this would solve some of your concerns...
