install a Data Protector Media Agent on the system with the device connected. Data
Protector can detect and automatically configure most standalone devices.
During a backup, Data Protector issues a mount request when the medium in a device
is full. The operator must replace the medium for the backup to continue.
What are device chains?
Data Protector allows you to configure multiple standalone devices to a device chain.
When a medium in one device gets full, the backup automatically continues on the
medium in the next device in the device chain.
Device chains allow running unattended backups using several standalone devices
without having to manually insert/eject media when the media are full.
Stacker devices
Stacker devices, similar to device chains, contain a number of media that are used
in a sequential order. When a medium gets full, the next medium is loaded and used
for backup.
Small magazine devices
What are magazine devices?
Magazine devices group a number of media into a single unit called a magazine.
Data Protector treats the magazine as if it were a single medium. A magazine has
a larger capacity than a single medium and is easier to handle than several single
media. For a list of supported devices, see the HP Data Protector product
announcements, software notes, and references.
Data Protector and magazine devices
Data Protector allows you to perform media management tasks on magazines as
sets, emulating single media by providing magazine and media views, or on a single
medium.
You can alternatively use magazine devices as normal libraries without using Data
Protector magazine support. Data Protector can detect and automatically configure
magazine devices.
Cleaning dirty drives
Using cleaning tapes, Data Protector can automatically clean magazines and other
devices when they get dirty.
