Backup Schedules

Backup makes it easy to set up your backup schedules. Deciding which backup schedules best fit your environment, however, requires a planned strategy.

When you create backup schedules, consider the following factors:

• The amount of data you have to back up

• The number of volumes you want to use

• The time you have to complete a backup

• Whether the number of volumes required to recover from a disaster, such as a disk crash, matter

Additionally, you must determine a policy for recovering files. For example, if users expect to recover any version of a lost file for at least three months (that is, the retention policy is equal to three months), you need to maintain all the save set entries in the media database for three months. On the other hand, if users only expect to recover data from the last month, you can use level 1-9 backups to decrease the quantity of volumes you need to maintain.

The length of time data is available for Backup to recover is determined by the browse and retention policies associated with each client. See "How the Browse and Retention Policies Manage the Data Life Cycle " for more information about how Backup manages the data life cycle.
