•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
