• media age
The age of a medium is calculated as the number of months that have elapsed
since you formatted, or initialized, the medium. Once a medium is older than the
threshold number of months, it is marked as poor.
• device errors
Some device errors result in the medium being marked as poor. If a device fails
during a backup, the medium used for the backup in this device is marked as
poor.
Media management after backup sessions
Once the data is stored on the media, you must take the right precautions to protect
the media and the data on the media. Consider the following:
• Protecting media from overwrites.
You have specified this when you configured a backup of data, but you can
change this after the backup is done. For more information on data and catalog
protection, see “
Keeping backed up data and information about the
data ” on page 99.
• Protecting media from physical damage.
Media with permanent data may be stored to a safe place.
• Copying backed up data and keeping the copies at a safe place.
See “
Duplicating backed up data ” on page 112.
The following sections describe how to vault media and restore from such media.
Vaulting
What is vaulting?
Vaulting is a process of storing media with important information to a safe place,
where they are kept for a specific period of time. The safe place for media is often
called a vault.
Data Protector supports vaulting with the following features:
• Data protection and catalog protection policies.
• Easy selecting and ejecting of media from a library.
• The field media location tells you the physical location where the media are stored.
