Hi everyone, I've got the first time today an error with my backup:
- 5 vms were successfully backuped
- 2 didn't and failed with:
Error: no writers left
- I restarted those two vms and one finished successful but the other didn't, this is the log:

any ideas what this error means, what could be the root cause? I've googled and searched in the forum for it, but couldn't find anything
