Hello- I have a Dell T620 running server 2012. The backup has been setup to go to a local usb drive. The backup intermittently fails on 1 of the volumes during the compression portion of the backup or will just fail out right with an error that says "There
was a failure in preparing the backup image of one of the volumes in the backup set. We are currently running ESET for an AV. I have tried uninstalling it to see if it was causing the issue and it didn't solve it.
I did notice that there are usually event id 153 source disk The IO operation at logical block address 0x22 for Disk 4 was retried during the backup time. Not sure if that is normal or not.
Here is the error from the app log that occurs when the backup fails - The backup operation that started at '2015-02-13T02:00:11.159719500Z' has failed with following error code '0x807800C5' (There was a failure in preparing the backup image of one of the volumes in the backup set.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
If I can provide any additional details please let me know.
