Backup: "ERROR: Failed to perform backup: error in addproc" (R3.2)

[qubes...@riseup.net]

Hi,

when trying to perform a backup of my VMs I get this error after about 75%

"ERROR: Failed to perform backup: error in addproc"

This is reproducible everytime. Which means I can no longer backup my VMs.

I'm using R3.2.

I found this error on the bugtracker but it was on R3.1 and is marked as closed:

https://github.com/QubesOS/qubes-issues/issues/1588


Anyone else observing this and know of a workaround?

thanks!

thanks!

I got it to work - backup done without failure.

Here is what I did:

'qvm-ls' was showing warnings about corrupt files for specific VMs.

Since these where old VMs that I deleted already in qubes manager I deleted them again with

qvm-remove --just-db <name>

Then I performed a backup. I'm not entirely sure if that was the problem since I deleted some more
VMs but it sound reasonable.

If this was indeed the root-cause:
Maybe qvm-backup could check if there are any warnings in qvm-ls output before proceeding?
