Backup

Scheduling Unattended Backups

• Each backup specification can be scheduled multiple times with different option values. Within one backup specification, you can schedule both ZDB disk and ZDB disk/tape backups, and specify a different data protection period for each individual or periodic scheduled backup.

• Data and catalog protection settings determine the period that data is

	kept on a medium (data protection) and in IDB (catalog protection).
	See “Data Protection: Specifying How Long Data Is Kept on the
	Media” on page 228 and “Catalog Protection: How Long Info Is Kept
	in the Database” on page 230 for details.
	• When applying a backup template, the schedule settings of the
	template override the schedule settings of the backup specification.
	After applying the template, you can still modify the backup
	specification and set a different schedule.
NOTE	You can schedule backups up to a year in advance. Periodic backups do
	not have a defined time limit. Weekly periodic backups can be configured
	only if the time between two recurring backups is at most four weeks.
Handling	When scheduling periodic backups, it can happen that the chosen backup
Scheduling	start time is already occupied by another scheduled backup in the same
Conflicts	backup specification. In that case, Data Protector prompts you that there
	are scheduling conflicts, and asks if you wish to continue. If you click
	Yes, the new schedule will be applied where possible (on the days when
	the time slot is still free). If you click No, the new schedule will be
	discarded.
Planning Your	See the HP OpenView Storage Data Protector Concepts Guide for
Scheduling	answers to questions such as:
Policies	• How do I plan a scheduling policy for my environment?
	• How does the amount of data influence my scheduling policy?
	• How long will the backup take?
	• How many media do I need for the backup?
	• How do I plan for a disaster recovery?
