why backup status is partial?

Why some backup is partial? can i run manually again to do the backup?

If the backup comes out partial, it typically means one of two things:

1. Your network storage system had a minor disconnection causing the backup to fracture.

2. Your backup was interrupted by a system process on the NLS end of things.

In either case, I recommend simply deleting the partial backup and re-running the backup & maintenance command to recover a working backup.
