Scheduling Unattended Backups

	Scheduling Unattended Backups
	Data Protector allows you to configure unattended backups by
	scheduling backups of your systems at specific times.
	The configuration and your scheduling policies can significantly
	influence the effectiveness and performance of your backup.
Key Points	• To simplify scheduling, Data Protector provides backup specifications
	for group clients. All clients configured in one backup specification are
	backed up at the same time in a single backup session.
	• Be sure to have sufficient media and devices to run unattended
	backups smoothly. See Chapter 7, “Monitoring, Reporting,
	Notifications, and the Event Log,” on page 307 for details on
	monitoring running sessions and setting up e-mail or other
	notifications for a mount request.
	• When the scheduled backup is started, Data Protector tries to
	allocate all the needed resources, such as licenses, devices, and access
	to IDB. If one of the needed resources is not available, the session is
	marked as queued. Data Protector will try to find the needed
	resources for the queued session once every minute until the time-out
	period is reached.
	Once Data Protector finds the resources, one of the queued sessions is
	started. The queued sessions are not started in the order they are
	displayed.
	• To prevent Cell Manager overload, a maximum of up to five backup
	sessions can be started at the same time. If more are scheduled at the
	same time, the sessions are queued.
	• For each individual or periodic scheduled backup, you can specify the
	following options: Backup type (full or incremental), Network load,
	and Backup protection. With split mirror or snapshot backup, in
	the case of ZDB disk or ZDB disk/tape backups (instant recovery
	enabled), you specify the Split mirror/snapshot backup option.
	For split mirror and snapshot backups, the backup type is ignored (it
	is set to full).
