It's a random error. I have 7 machines giving this error from this past weekend. On one of those problem machines I kicked off a backup job by hand and it's worked fine (Took 6 minutes to backup).

Also the logs no longer export. If you try to save the logs you get a compressed file but inside it is a 0 kb XML file. .

Hello Keith,

Thank you for posting this issue.

I have in our internal databases searched for this error, but found nothing suitable. This error can have several causes:

  • The free space in the datastore is smaller than the largest virtual disk to be backed up.
    Solution: Add more memory to your datastore, add or relocate the virtual appliance on a datastore that has more free space.
     
  • The location for the backup is unavailable or the connection to that location stops more often.
    Solution: Set a higher volume at Re-attempt if an error occurs also at Number of attempts.
     
  • You do not use the latest build of Acronis vmProtect 7.
    Solution: Update to latest Build. We have an article for these steps in our Knowledge Base.

If these steps do not solve your issue, or you need additional assistance, then please contact our Acronis Support. You will find more Information about these steps in our Customer's Handbook.

Please let me know if you have additional questions.

Thank you.
