Solution description
HP Data Protector software is a backup and disaster-recovery software that provides reliable data
protection and high accessibility for your fast growing business data. Data Protector offers
comprehensive backup and restore functionality specifically tailored for enterprise-wide and
distributed environments. Data Protector can be used in environments ranging from a single system to
thousands of systems on several sites. Due to the network component concept of Data Protector,
elements of the backup infrastructure can be placed in the topology according to user requirements.
The numerous backup options and alternatives to setting up a backup infrastructure allow the
implementation of virtually any configuration you want.
HP Data Protector enables you to perform backup to a large number of backup devices
simultaneously. It supports high-end devices in very large libraries. Various backup possibilities, such
as local backup, network backup, online backup, disk image backup, synthetic backup, backup with
object mirroring, and built-in support for parallel data streams allow you to tune your backups to best
fit your requirements.
As Data Protector supports heterogeneous environments, most features are common to the UNIX and
Windows platforms.
The Data Protector cell is a network environment that has a Cell Manager, client systems, and devices.
The Cell Manager is the central control point where Data Protector software is installed. After
installing Data Protector software, you can add systems to be backed up. These systems become Data
Protector client systems that are part of the cell. When Data Protector backs up files, it saves them to
media in backup devices. The Data Protector internal database (IDB) keeps track of the files you back
up so that you can browse and easily recover the entire system or single files. The HP Data Protector
Cell Manager also runs session manager processes that start and stop backup and restore sessions
and write session information to the IDB
The UNIX and Windows Cell Managers can control all supported client platforms (UNIX, Windows,
and Novell NetWare). The Data Protector user interface can access the entire Data Protector
functionality on all supported platforms.
It is crucial to the operation of a cell that the HP Data Protector Cell Manger system is properly
planned and setup in order to be able to cope with the various performance aspects in such a
complex environment.
