Each computer user is ultimately responsible for his or her own data!
Since you could miss a deadline, or find that a system backup is defective, you are strongly encouraged to backup important files to your own diskettes. This is a very wise policy anyway, to allow for unplanned system outage or your own mistakes. If the file is very important, be sure to verify the integrity of the backup and perhaps use more than one backup. Perhaps the most likely need for a backup on diskette is to provide for times when your home directory is inaccessible due to network or system failure.
Currently, user files are not backed up! Each individual should back up their own files to diskette or by other means.
