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.
