Executive summary
Data protection has never been more important—data is the lifeblood of any modern company. With
the advent of lower cost Serial ATA (SATA)–based disk arrays, disk-assisted backup has been making
inroads into areas where physical tape drives were once the primary means of data protection. Tape
will always be the lowest cost storage technology, but the role of tape is changing. Tape remains the
foundation of a comprehensive data protection strategy because of its low cost/GB and the ability to
physically remove the tape media and store the data offsite. Tape is being used more and more for
high-volume data backup (from fast data sources), long-term archiving, and the migration of data that
has already been backed up to disk.

Virtual tape libraries from HP offer a seamless migration to a disk-assisted backup strategy because
they emulate existing HP tape drives and libraries, while protecting a customer’s investment in backup
software. They appear as “real” physical libraries to the backup software, enabling all existing
processes and procedures to be used.

The HP StorageWorks 6000 Virtual Library Systems (also called the VLS6000) offer up to 70 TB of
backup storage (up to 140 TB with software data compression and 2:1 compressible data) at
combined data rates of up to 600 MB/sec.

The HP VLS6000 is primarily targeted at:
• Reducing long backup windows due to slow servers being unable to stream higher performance
tape drives in a SAN-based environment. “Slow” in this sense is related to the data type being slow
to access, for example, file and print or web servers. This reduction in backup time is achieved by
running multiple backups in parallel to several virtual tape drives on the VLS6000.

• Environments that have to perform single file restores on a regular basis. Because the VLS6000 is
disk-based, restoring a specific file is much quicker than restoring from tape.
• Data that only has a short life span, for example, transaction logs in Oracle®, SQL, and
Microsoft® Exchange.
• Those who are using clone or snapshot technology (and hence expensive high-performance disk
arrays) for backing up non-critical data. The VLS6000 provides a more cost-effective way to protect
non-critical data.
