When a SQL Backup Master job executes, it will ultimately end up in one of four different states:
•Succeeded - This state represents a successful backup.
•Warning - Indicates that one or more warnings were logged during backup.
•Errored - This state indicates that the backup was successfully uploaded to at least one backup destination, but others failed.
•Failed - Indicates that all backup destinations failed, or some other critical error occurred.
•Canceled - The backup job was canceled by a user or by system shutdown.
Note: A backup job can also be in a Running (backup in progress) or Never run (job was created but not yet run) state.
