Managing Backups and Backup Media
Maintaining a Backup Library
system's data, and an easy method for locating the data you want to recover.
There are two reasons you should always keep older backup data in addition to your
current backup data: in case the most recent copies are bad, and for restoring older files
that may have been removed from the system some time ago. In such situations, you can
restore files from the most recent intact copy.
To set up a library, perform the following steps:
• Obtain a substantial number of backup media. The exact number you need depends on
how much data you will be storing and how long the backup data will be retained.
• Obtain a container such as a vault, a metal cabinet, or rack in which to keep the backup
data.
• Establish a control program for maintaining backup data for a specified length of time.
• Establish a cleaning and verifying schedule for the media devices.
• As part of your disaster recovery plan, create a duplicate library in a safe, offsite
location. Refer to Chapter 13, "Disaster Recovery," for more information.
