I'm trying to setup Windows Backup to backup my laptop to a network attached storage drive. The backup runs for about an hour an then fails giving error code 0x8078015B.
When I checked the windows error log I find the entry I've listed bellow. Any one any idea how to resolve this? If I have to disable services one by one it could take me weeks to figure out what is causing the issue.
