I am running HA in a VM (hyper-V) and using a SAMBA share for backup. What I’ve noticed is if you reboot HA it looses the Samba share but if you reboot the system (in advanced options) the backup will work. It seems there may be a timing issue or some link / mount is not being recognized when one just boots HA normally. That’s obviously bad because every integration change means a new reboot with core releases coming so often.
