Hi all,

Can anybody explain what is going on here?

Oh, I see the error now. The output redirect to "/mnt/pve/qnap_nfs" looks strange to me. Please can you post your storage config?
 
Plenty:
192.168.2.10:/vz 1,4T 891G 483G 65% /mnt/pve/qnap_nfs

I have even tried with a backup of the CT using mode stop. It also fails with almost identical error:

Some background:

Do you get the same error if you use no compression (or gzip)?

Very strange. Today it works. Only difference between today and yesterday is that I have taking this CT out of HA? Another hint: Another CT which was not under HA had no problems with backup when the backup of this CT failed which was under HA.
