| My device is rooted and I use NeoBackup to backup apps with all their data (including what the app developer marked as "should not be backed up", often data that they would like you to backup on their own cloud instead). Syncthing synchronises these backups to my home server automatically, as well as the phone's user data (photos, mainly). The photos are additionally sent to Photoprism. I avoid Google's cloud as much as I can. |
I used Nextcloud sync in the past, but found it unreliable.
