We configured an Azure Backup for our Windows Server 2012 R2, but every time it tries to run the actual backup we received this error:
An unexpected error occurred during the operation. Retry the operation (0x07EF9).
We looked at the log files and pinpointed this line where is has the same error code:
[0x80070020] Setting error on File provider 000000001ABB1090. DlsErrorCode = 0x7ef9
Can someone shed a bit of light at the possible cause of this issue? So far I cannot find any information where to even start.
Much thanks in advance.
