Managing Media

Creating a Media Pool

	medium is used first. If additional media are needed
	during the same backup session, they must be free and
	not contain any protected backups. This media usage
	policy will create media which will contain a full
	backup, followed by any number of incremental
	backups.
NOTE	If you use the append functionality and the backup requires more than
	one medium, only the first medium used can contain backed up data
	from a previous session. Subsequently, Data Protector will use empty or
	unprotected media only.
	See “Appending Backups to Media” on page 117 and “Selecting Media for
	Backup” on page 120 for more information.
Magazine Support	Magazine support allows you to use a set of media configured as
	magazines. A backup device used with these media must have support
	for magazines, such as the HP 12000e.
	You can set this option when you configure a new media pool.
	See the following sections for more information:
	• “Configuring Magazine Devices” on page 34 for instructions on how to
	configure a magazine device.
	• “Formatting Media” on page 108 for instructions on how to format a
	full magazine or a single medium in the magazine.
	• “Importing Media” on page 113 for instructions on how to import a
	full magazine or a single medium.
Media Condition	Media condition factors define the status of the media, thus determining
Factors	how long media can be reliably used for backup. If a pool uses the free
	pool option, the media condition factors are inherited from the free pool.
	Data Protector calculates the status of media in use via media condition
	factors. The two media condition factors you can select are:
	Medium valid for The age of a medium is calculated as the number of
	months that have elapsed since it was formatted. Once
	a medium is older than the threshold number of
	months, it is marked as poor. The default threshold is
	36 months.
