If you see highlighted messages there are two reasons error

1. failed with the following error: "xp_create_subdir() returned error 161

First check SQL server or SQL Server Agent service running using the local or service account and the account should have enough privileges on the backup folder

2. Cannot open backup device. Operating system error 5(Access is denied.)

Check whether the account have read/write privileges on the backup folder.

In my case I see that SQL Server Agent running using a local account and that account don’t have permission on the backup folder. I have changed the SQL Server Agent “Log on As” account to service account which has permission and restarted the service.
