hi I installed koha 22.11 on ubuntu using the package for Debian (https://wiki.koha-community.org/wiki/Koha_on_Debian). I wanted to set up automatic backups using the "koha-run-backups" command. However, it's not entirely clear to me how the command works: 1) can I just run the command as root and the backup will start, or do I also need to set something in the system crontab? 2) How often (and when) is the backup performed? 3) What to do if I want to stop automatic backup? Thank you! :)
