[SOLVED] Backup is failing with exit code 1

When we try to Backup a container we get the following output:

I searched for tar: ./var/..._amd64.deb: File shrank by 43806 bytes; padding with zeros, but it seems to be only an info and not and error. But the backup for other containers without this message does not fail.
I updated proxmox to the latest version today, but the problem existed before that too.

Hi!

Do you still have this problem? If yes, could you please try to create a backup

• of another container to the same target storage without compression
• of this container to a different target storage (e.g. local) and without compression

and also post the following?

pct config 107
cat /etc/pve/storage.cfg # not all storages are necessary

Hi,
the problem was the disk which had sector errors.

Great that you could solve the problem!
It would be nice if you could mark the thread as solved by editing your top post and changing the prefix. This way, others know what to expect when clicking on it.
