Advanced Backup to Disk Performance White Paper

Introducing HP OpenView Storage Data Protector 5.5

HP OpenView Storage Data Protector (DP) is software that manages backup and recovery from both

disks and tapes, delivering maximum data protection while providing continuous 24x7 business

operations. The software is designed to simplify and to centralize backup and recovery operations by

integrating a variety of techniques to eliminate backup windows. These range from on-line backup,

open file backup, and instant recovery or zero-downtime backups.

HP OpenView Storage Data Protector simplifies the use of complex backup and recovery procedures

with the fastest installation, automated routine tasks, and easy-to-use features. The ideal solution to

reduce IT costs and complexity while remaining reliable and scalable to grow from single server

environments to the largest distributed enterprise infrastructures, providing broad compatibility of

operating systems, applications, drives, libraries, and disk arrays.

The Advanced Backup to Disk feature improves the backup process with continuous backup of

transaction log files, backup of slow clients without multiplexing, easy resource access and sharing,

plus backup in tape-less branch offices, while offering fast and easy configuration and licensing.

Furthermore, it allows single file restore directly from disk or tape.

The following subchapters

File Library and Object Copy give a short overview about the features

required for Advanced Backup to Disk.

File Library

DP provides a device type called “File Library”. It focuses on low cost disk arrays, especially the

current HP SATA disk array, which is positioned mainly as a backup device. In case the file library is

running out of free space, new backup capacity can be assigned automatically.

The file library is configured by defining mount points where DP will create its “media” and

optionally, the number of simultaneous “writers” that will be used. Then, DP can utilize this just like

any other physical backup device and will auto-create the media files on the fly as required. This

capability is called “Advanced Backup to Disk”.

Object Copy

Object Copy provides the capability to copy from one type of media to another. This means that you

can perform a backup to the file library, and then automatically (immediately after backup or at a

scheduled time) copy the file-based “media” to a physical media such as LTO.
