Hello,

I try to backup data with the proxmox backup client.

Technical data:
- pbs: V. 2.2.3
- client: Linux Debian with proxmox backup client V. 2.2.1

At the beginning, everything works fine. But since maybe 2 hours oder 4 hours, the backup failed.

I add "--verbose" to the client and
- on client side the log output suddenly stops. At last try there was "http/2.0 connection failed" as last log entry. But not everytime.
- on server side these were the last entries:


Code:

I had to backup over 300 GB of data.

Is there the possibility to restart/resume backup and do not start from the beginning?
Or is there another switch to have more details on the log why it fails?


thanks for helping

Alex

Hi, I'm facing the same issue out of the blue.
My data backup runs every week and the pool is roughly 30Tb big, usual backup size is around 900Gb. Since this week, the backups for this particular job fails with:

Bash:
HTTP/2.0 connection failed
catalog upload error - channel closed
Error: pipelined request failed: connection reset

Did you ever fix this?
Or does anyone have an idea? my system details are below the spoiler
