Can't restore from USB drive Hello,
Regarding your issue.
1. The error you're seeing during restore is related to NTFS permissions.
Please start Backup Service under administrator account: go to Tools > Change Service Account, enter local administrator account name and password, click OK. The service will be restarted automatically.
It is generally recommended to use local administrator's account name because domain administrator is not always a local admin on the host machine.

2. AD warning messages can be ignored, they are irrelevant in this case.
3. Regarding the backup prefix(computer name): you can change it by editing your storage account and going to "advanced options" menu. There you can choose computer name. This is used to identify your data on storage.
So to fix the issue you just need to solve the permissions problem by making sure the software uses account that has full access to the files and folders, and then select your preferred backup prefix.
