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

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.

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?
