it seems to be indeed storage-related problem. I could only find that the export task failed due to

106774fb-1093-495a-a996-48f48e066a6f::ERROR::2016-05-07 18:04:15,998::blockVolume::429::Storage.Volume::(validateImagePath) Unexpected error

Then i started working on the problem (among other things, i added a new backup storage domain) and you can se around 8 PM that another VM failed the backup, this one called "biblioteca".

It's not always the same VM that fails, but once it fails on a certain storage domain, I cannot export it anymore. Please tell me which logs are relevant so i can post them and any other relevant iformation I can provide, and maybe someone can help me get through this problem.
