Automated media copying
What is automated media copying?
Automated media copying is an automated process that creates copies of the media
containing backups. This functionality is available with library devices.
Data Protector offers two types of automated media copying: post-backup media
copying and scheduled media copying.
Post-backup media copying
Post-backup media copying takes place after the completion of a backup session. It
copies the media used in that particular session.
Scheduled media copying
Scheduled media copying takes place at a user-defined time. Media used in different
backup specifications can be copied in a single session. You create an automated
media copy specification to define which media will be copied.
How does automated media copying operate?
First you create an automated media copy specification. When the automated media
copy session begins, Data Protector generates a list of media, referred to as source
media, based on the parameters specified in the automated media copy specification.
For each source medium, a target medium is selected to which the data will be
copied. The target media are selected from the same media pool as the source media,
from a free pool, or from the blank media in a library.
For each source medium, Data Protector selects a pair of devices from the devices
that you specified in the automated media copy specification. The automated media
copy functionality provides its own load balancing. Data Protector tries to make
optimum use of the available devices by utilizing as many devices as possible and
selecting local devices, if they are available.
The automated media copy functionality does not handle mount or cleanme requests.
If a mount request is received, the media pair concerned is aborted, but the session
continues.
For examples of use, see “Examples of automated media copying” on page 332.
