Getting started states you need root access across servers, you do not. #186

The getting started guide states: "With a pull backup, the target machine will have root access to the source machine."

The zfs allow will allow you to grant send, snapshot, hold and other required permissions on a dataset. Thus not requiring "root access to the source machine." You can grant those to any account on the source machine.

you are right, but then you make sure your user has write access to /dev/zfs as well.

i'll update the documentation to reflect this, thanks

I added a note https://github.com/psy0rz/zfs_autobackup/wiki#setup-ssh-login and i changed that text to 'ssh access' instead of 'root access'

In setting up, the account will need destroy,hold,mount,release,send,snapshot as in:

zfs allow USER destroy,hold,mount,release,send,snapshot tank/dataset`

On Ubuntu 22.04 LTS it looks like /dev/zfs is world-writable by default. I don't recall changing that. Other distros may vary.
