TIPS
1. Backup devices are affected by the media type. For most backup devices the right media and density
can greatly affect the capacity and speed of your save or restore operation. USE THE RIGHT
MEDIA FOR YOUR BACKUP DEVICE. (i.e. Use a 25 GB tape cartridge in a 25 GB drive).
2. A Backup and Recovery Management System such as BRMS/400 is recommended to keep track of
the data and make the most of multiple backup devices.
