• Overall, disk-based storage space is becoming increasingly cheaper even if

compared to tape-based storage.

Data Protector disk-based devices

Data Protector has the following disk-based devices:

• Standalone file device

• File jukebox device

• File library device

Standalone file device

The standalone file device is the simplest disk-based backup device. It consists of a

single slot to which data can be backed up. Once configured, its properties cannot

be changed. The file device has a maximum capacity of 2 TB, if this file size is

supported by the operating system on which the device is running.

File jukebox device

The file jukebox device is a special version of the Data Protector jukebox device. The

jukebox device can be configured to back up either optical or file media. The jukebox

device used to back up file media is referred to as the file jukebox device. The type

of media to be backed up by the jukebox is specified during device configuration.

The file jukebox device consists of multiple slots to which you can back up data.

Configuration is a two phase process, firstly a file jukebox device is created and

then one or several drive(s) is configured for it. Once the device has been configured

it is possible to change its properties. Each slot in the file jukebox device has a

maximum capacity of 2 TB. The device’s maximum capacity is equal to:

Number of slots X 2 TB

File library device

The file library device is the most sophisticated disk-based backup device. It has

multiple slots called file depots to which you can back up data. The configuration of

the file library device is completed in a single stage. It is possible to change the

properties of the file library device at any time. The device’s maximum capacity is

the same as the maximum that can be saved on the filesystem on which the device

resides. Each file depot has a maximum capacity of up to 2 TB. File depots are

created automatically as required.

The file library device has intelligent disk space management. It anticipates potential

problems saving data to it. A warning message is written in the event log if the amount
