I’m regulary installing new versions of Nextcloud. I follow the guide in
https://docs.nextcloud.com/server/latest/admin_manual/maintenance/manual_upgrade.html . What is to backup before updating ? I have three BTRFS Subvolumes: /, /var, /home. My data folder is in /home. Is it enough to keep the folder nextcloud.old ? Or do i habe to backup more ?
Btw: is there a repository for Ubuntu with reasonably current versions ?
