Hi, 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 siz…

I’m a bit confused as to why you’re connecting a flash drive to sys-firewall and telling the Qubes Backup tool to create your backup in that qube. That seems like an odd and unintended use of sys-firewall. Any special reason for that? I suspect the problem might be with your flash drive (or the way…

Not a solution, but why are you storing your backup in a net-connected vm?

I’m not - its on a flash drive which is mounted on that VM, and the wifi switch is tripped to stop access. However, you have raised a point which is kind of hard to defend…

You were right. I created a new backup qube, stored the file there and it verified ok. I then SCP’d it over to the other box where backups live.
