cron utility to schedulc daily databasc backups at 2:00 a.m.
To schedule the Oracle-suggested disk backup strategy:
1. Ensure that you are logged in to the database host as a user who is a member of the OSBACKUPDBA operating system group (typically the backupdba group). The cron job will run as this host user.
2. Start a text editor, and create and save a file with the following contents into your home directory. Name the file .crontab. (Notę the period at the front of the file name.)
