1. Preparing media for backup.
This includes initializing (formatting) media for use with Data Protector and
assigning media to media pools, which are used to track the media.
For more information, see “ Media management before backups
begin ” on page 145.
2. Using media for backup.
This defines how media are selected for backup, how the condition of the media
is checked, how new backups are added to the media, and when data on the
media is overwritten.
For more information, see “ Media management during backup
sessions ” on page 147.
3. Vaulting media for long-term data storage. You can use one of Data Protector’s
data duplication methods to make copies of the backed up data for vaulting
purposes.
For more information on vaulting, see “ Media management after backup
sessions ” on page 151.
4. Recycling media for new backups once the data on the media is no longer
needed.
5. Retiring media.
Once a medium has expired, it is marked poor and will no longer be used by
Data Protector.
See “ Calculating media condition ” on page 150.
Media pools
Data Protector media pools manage large numbers of media, hence reducing the
management effort for the administrators to a minimum.
What is a media pool?
A pool is a logical set, or group, of media with a common usage pattern and media
properties. It can only have media of the same physical type. DLT and DAT/DDS
media cannot be in the same pool for instance.
The current location of a medium has no influence on its relation to the pool. Whether
the medium is in a drive, in a repository slot of a library, in the vault or somewhere
