So this is strange issue that started occurring about a month ago, and I have been unable to find any useful resources online. This may or may not be related, but this started happening very soon after we migrate our VM disks to a new datastore on a new storage device in vmware. I have managed to get at least one successful backup weekly, but this is after many failed attempts with the same errors.
I originally thought this was a Backup Exec issue but after spending hours on the phone with them they declared that this is a Microsoft issue since the same problem occurred using Windows Server Backup as well.
Here are the errors occurring. This typically happens during the System State Backup or during the C: drive backup.

The backup operation that started at '2017-09-20T13:04:54.929785700Z' has failed with following error code '0x807800AF' (The Volume Shadow Copy Service backup complete operation failed. See the event logs for more details.). Please review the event details for a solution, and then rerun the backup operation once the issue is resolved.
Has anyone ever seen or encountered these problems before? They are making backup up our server almost impossible. Any suggestions would be greatly appreciated.
Thank you!
