I've tested the SMB backup several times and it is working fine but I have noticed an issue you may want to investigate. When I toggle back to the internal storage backup location, backup does not auto-start on those apps which have been updated over the past few days. First I tried refreshing, then force stopping the app. Even when the app starts back up, the apps are shown as needing backup, but the backup doesn't start. It is only when I manually select them and force a backup does it work. AD has always automatically updated backups when first started. So after a successful, automatic backup of stale apps over SMB then toggling over to internal storage a user has to manually select the apps (clearly indicated as out of date) and force a backup. Is there a way to trigger the auto-backup after selecting a different saved backup location? Failing that, create a new context menu item to backup only those files that are outdated. This option would seem to be a no brainer because currently there is only a "backup all auto-backups" option which updates all of them, not just the outdated apps. Everything works as expected if a user sticks with one single backup location, but toggling to a different location is when the issue occurs. Thanks!
Update all backups from the context menu will update all the outdated backups
There will also be a sync locations option added later.
