Restore

A restore is the process of copying data from backup media to its original location or to a new location
in the event that the original location is damaged or unavailable. Restore operations can also retrieve
data to a file or folder other than the original one.

Disaster recovery

Disaster recovery is the ability to quickly restore critical systems and data from "bare metal" after a
disaster. A disaster can range anywhere from an isolated hardware failure (server or hard disk) to a
wide-spread natural disaster (fire or flood). Successfully recovering from a disaster requires pre-planning
to ensure that critical systems and data are fully backed up and those backups are available quickly if
needed. The disaster recovery process restores the operating system and applications onto the new or
repaired computer from the most recent system backup. A general restore operation can then be done to
restore the critical data.

Architecture

Data Protector Express installs onto your existing computer network. A network connects file servers,
application servers, and user PCs together in order to allow various users to work together on projects
and with common files. Networks also allow users to share peripheral devices, such as disk drives,
printers, fax machines, and modems.
Sharing devices across a network makes economic sense, since several systems can use a single
device. Backup devices, such as tape drives, hard disks, NAS appliances, and CD or DVD recordable
devices, which back up or copy files onto tape, disk, or other media, may also be shared. Sharing
a backup device makes operational as well as economic sense. Sharing devices lowers costs and
makes it possible to centralize backup operations across the network. Further, a single user, such as the
network administrator, can have primary responsibility for backing up all the file or application servers
and user PCs on the network.

Workstation or user PC — a computer that is typically used by a single person to do their work using
interactive applications such as word processors, spreadsheets, and e-mail.
Server — a computer that runs background applications that provide services to users. Examples are file
servers, application servers, and database servers. These machines are typically not used interactively.
