Hi,
Since I set up the automatic backup of one of my VMs, the backup has not been consistent : every two days it will fail with "exit code 1" and no more explanation. And some times (not very often), it will work for 3-4 days in a row and then, fail again.
My configuration :
- vm-100 : disk qcow2 of 500GB (only 350GB used)
- backup on external disk of 1TB
- backup is launched every night at 10pm
Error :
I've read all the 10 pages of search for backup failed but did not find any answer for this problem.
Exit code 1 is not very explicit for me.
I have found that the error might be from "Failed to create message: Input/output error" but cannot find how to correct this.
Do you any ideas for what happen here ?
What can I do to investigate further ?
Thanks for your help !
