Stopping backup to allow backup destination disk to be unmounted or ejected.
Backup failed because the destination disk was ejected or disconnected unexpectedly!
**The last line I expect is because I manually ejected the "Time Machine Backups" disk (because it didn't auto eject)**
Update: I backed up again, but this time didn't manually unmount the disk, and this is what the backup widget is showing:
Backup completed successfully.
