Hello,
I'm using Microsoft Azure Backup on a Windows Server 2012 R2 to backup some folders on a local D:\ and E:\ drive. Since a few weeks the backups of drive E: fail with an error. The complete error message is:
Backup has encountered an irrecoverable error. Contact Microsoft Support for further assistance. (0x086C8)
To resolve this issue, I tried to follow the steps provided in this thread:
https://social.technet.microsoft.com/Forums/en-US/windowsazureonlinebackup/thread/82c982fa-103a-4bef-b0d4-ecea2f4ce4f3
These steps however, doesn't seem to fix the issue for me. Backup still fails with the exact same error.
In my Azure Backup Console I can see 4 jobs (it only ran once after doing the steps from the other thread). The oldest one has the status 'Job completed with warnings'. This one tells that the backup of drive D:\ has been completed and that drive E: failed. The other 3 are just 'Job failed' jobs.
I also checked the CBEngineCurr.errlog and there seem to be some corruption:
