of free disk space approaches the configured minimum amount required for the
device to work. This enables you to free more disk space in good time for the device
to continue saving data. If all the space allocated to the file library device is ever
completely used, a warning message appears on the screen with instructions as to
how to solve the problem.
The file library device automatically creates more file depots if a particular backup
requires more space than is available in a single file depot.
Recommended disk-backup device
Hewlett-Packard recommends using the file library device as the preferred disk-based
backup device. The file library device is the most flexible and intelligent of the set of
disk-based backup devices. It can be re-configured at any time during use and is
capable of performing more sophisticated disk space handling than any other
disk-based backup devices. Furthermore, it enables the use of advanced backup
strategies such as synthetic backup.
For description of the file library device functionality, see the online Help index: "file
library devices".
Data format
The data format of the disk-based devices is based on the tape data format. Data
Protector converts the data to be backed up into tape format before it writes the data
to the disk-based device.
With file libraries used for virtual full backup, distributed file media format must be
used. Select this format in the device's properties.
Configuration
It is possible to set properties for the all disk devices both during the initial device
setup and after the devices are in operation. The degree of changes that can be
made to the properties of each device vary according to the device.
Backing up to a disk device
A backup can be made to a disk-based device by creating a normal Data Protector
backup specification.
