[SOLVED] Restore .img from PBS to a /dev/sda

Jul 20, 2022
I have a PBS backup like this:
Screenshot from 2023-06-04 01-47-07.png
It was created thusly:
export PBS_PASSWORD=<password> export PBS_REPOSITORY=dan1@pbs@ proxmox-backup-client backup \ system.img:/dev/disk/by-id/ata-1TB_SATA_SSD_AF20011703077 \ --keyfile=/etc/priv/PBS.enc \ --ns=rocky

And, I have a VM on the same Proxmox host that has a blank disk /dev/sda. This VM is booted from a USB drive that has proxmox-backup-client installed.

I'm trying to figure out the command that will restore the image backup to /dev/sda.

Here's what I have so far:
sudo proxmox-backup-client restore \ host/PBSclient/2023-05-26T04:10:02Z \ system.img \ /dev/sda \ --repository dan1@pbs@ \ --keyfile=/etc/priv/PBS.enc \ --ns rocky

Here's what happens:
Password for "dan1@pbs": *********** storing login ticket failed: $XDG_RUNTIME_DIR must be set Using encryption key from '/etc/priv/PBS.enc'.. Fingerprint: 1e:f6:69:0e:05:61:5c:bb Error: unable to create target file "/dev/sda" - File exists (os error 17)

How do I specify the target?

Thanks. :)

Ok. This is what I ended up with. I guess the backup command accepts a block device as input, but the restore command does NOT accept a block device as output. So, I piped it to dd.
export PBS_PASSWORD=<password> export PBS_REPOSITORY=dan1@pbs@ # restore proxmox backup image: sudo -E proxmox-backup-client restore \ host/PBSclient/2023-05-26T04:10:02Z \ system.img \ - \ --keyfile=/etc/priv/PBS.enc \ --ns rocky \ | sudo dd of=/dev/sda bs=256M status=progress

I did not need to boot this image, so that part was not tested.
