The NetWorker servers are used to save and restore file systems to and from tape backups. This is done simply by making sure the desired tape is in the drive and labeled correctly, then clicking the mount button on the networker application. This is done by clicking the unmount button on the networker application. The tape can now be removed from the drive. This is done by making sure the desired tape is in the tape drive, clicking the label button on the networker application, selecting whether the tape is to be full or incr , and then entering the label for the tape.
Tape labels are case sensitive.
Carefully check to see that your casing is correct before committing the label. Throw the tape away and get a different one. If you relabel a tape all information is removed. That's why on the incremental you recycle a tape by merely relabling, same for fulls. If you make a mistake on a full tape there's nothing you can do, just leave it as is.
