Hi,
My windows backup backing up to NAS folder and worked fine, but now windows backup is failing with error code "0x8078004F"
The backup operation that started at '2021-06-19T18:00:07.880845800Z' has failed with following error code '0x8078004F' (The mounted backup volume is inaccessible. Please retry the operation.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.

Backup works only for local hard drives (bare metal, c, d) and fails when backup start to copy Hyper-V. Only option to backup hyper-v is on externel USB HDD. Backup do not works on network folder. I tried to change location to another NAS, but i still have same error.
