Backup
Scheduling Unattended Backups
Chapter 5 208
• 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
Scheduling
Conflicts When scheduling periodic backups, it can happen that the chosen backup
start time is already occupied by another scheduled backup in the same
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
Scheduling
Policies See the HP OpenView Storage Data Protector Concepts Guide for
answers to questions such as:
• 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?
