How to setup HA to recover if there is ever an issue or corruption?

Where can i find the samba “share” name, is this a default value? i didnt create any share names…

I believe i got the samba issues resolved lastnight and today ill see if the scheduled back up ran…
If it did run(full backup) what are some suggestions on restoring to that back up?

I was thinking the following:

Add a few add-ons that are not part of lastnights back up.
Reboot the device and execute the restore from the command line?
Or restore from the interface?

Which is a better option?

And if it is successful and see that the new add-ons i add before hand are not there, then would i consider that a successful restoration?
