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).
