I use it on cheap vps since ~4yrs and work "well" but I've never had a single major update that didn't have an issue on my LXC/Alpine container ๐ One moment it's the packages name that have changed, one time it's PHP version, another it's a config, another is a addon, last time that was opcache, ... and I'm a bit tired of having to spend hours each time doing maintenance of it.
I really think I'm going to go back to something simpler but more solid like an SSHFS or similar.
personnaly i have try a lot Syncthing at different times and all times I had synchronization problems in the first minutes of testing with few files (between android lineageos and/or two linux desktop)
(fw, ip, setup, are "fine", so i dropped and go back with nextcloud/rsync/kdeconnect -_-)
