• Scanning the barcodes of the media in a device’s repository is faster, because
Data Protector does not need to actually load the media to a drive and read the
medium header.
• A barcode is automatically read by Data Protector and used to identify the media.
• A cleaning tape is automatically detected if it has a CLN barcode prefix.
• A barcode is a unique identifier for media in the IDB. You cannot have duplicate
barcodes in your environment.
TIP:
You can optionally use the barcode as medium label during the initialization of the
medium.
Cleaning tape support
HP Data Protector provides automatic cleaning for most devices using a cleaning
tape. This medium will be used automatically by Data Protector if a dirty drive event
from the device is detected.
• For SCSI libraries it is possible to define which slot holds a cleaning tape.
• For devices with a barcode reader, Data Protector recognizes cleaning tape
barcodes automatically if they have the CLN prefix.
• For devices without a cleaning tape, a dirty drive detection will cause a cleaning
request to be displayed on the session monitor window. The operator must clean
the device manually.
You cannot continue your backup without cleaning the drive, since the backup
may fail because data may not be correctly written and stored on the media.
Sharing a library with multiple systems
What is library sharing?
Device sharing allows you to connect different drives of a physical library to different
systems. These systems can then perform local backups to the library. The result is
significantly higher backup performance and less network traffic. To enable library
sharing, the drives in the library must have the possibility to connect to separate SCSI
buses. This is useful with high performance libraries to allow the drive to receive data
in a continuous stream from multiple systems, further enhancing performance. Data
