For Linux/Admin Class (Backups):

Use Dump (commands) (as an example: dump 0 f /dev/rmt0 /dev/da0)

1) Give the dump commands that you would add to root's crontab (crontab -e) that will perform an incremental daily backup on all user directories and a full backup of the entire system once a week.

2) Give the dump command to restore the file lab10.txt from your home directory off of the backup dataset created by the previous question.
