The NetBackup administrator configures the policies that define the rules that NetBackup follows when it backs up clients.

The policies include schedules for automatic, unattended backups of the NetBackup clients (server directed backups).

Policies also define when you can back up files manually (user directed backups).

For example, the time range in which you can perform user-directed backups (your user window) is from 8 A.M. to 6 P.M.. You cannot back up or archive at any other time although, you can restore files at any time.
