File backup fails with error 0x0223007FC0000034

[martin]

I have a VeraCrypt encrypted partition which I want to make file backup.
No VSS is enabled on that partition and BackupWorker.log says:

My assumption is that because the partition has no VSS enabled that the error  VSS_E_OBJECT_NOT_FOUND occurs.
Is there a way to make backups of such partitions?
