Qubes Backup Verify fails

When I verify a backup (via the GUI), I get the following error:

Failed to decrypt […]/private.img.enc: b’scrypt: Input is not valid scrypt-encrypted block\n Partially restored files are left in […], investigate them and/or clean them up.

Am running the backup through sys-firewall. Backup size is c. 44gb. There is c. 120 gb free on the disk, I’ve given sys-firewall a 100gb private storage max. Have tried to verify a few times and the results are the same.

Any ideas?

Maybe these two threads help:

Thanks - Didn’t come across the second one when looking into this.
Will try a fresh backup with no compression and see how that goes.

Tried with no compression. Same error results when I try to verify
