A backup and recovery system is an integral part of a company's data security. The ability to back up
and restore data quickly and efficiently can mean the difference between survival and failure. Data
Protector Express provides users with the capability to back up and restore data across a network as
part of a comprehensive backup plan. This section describes basic concepts of a backup and recovery
system and how these are implemented with Data Protector Express.
Whether your work environment consists of a single computer in a home or small office, several computers
connected to a network server, or hundreds of computers connected to multiple network servers, a
minimum data protection plan requires the ability to back up and restore all of the important data files.
At a minimum, data that cannot be reloaded onto the system from installation disks, network-based
security settings, company-generated databases should all be backed up for easy retrieval in the event of
a data disaster. The important data might be a word processing file, e-commerce transactions, network
user account and password information, and so on.
The data you protect and how long it remains available on backup media will depend on legal
requirements for your industry and your own company policies. Whatever your data storage requirements
might be, you should have a basic understanding of the types of backup operations and your own
computer environment.
Backup
A backup is the process of copying a file or folder to backup media, such as a cartridge loaded in a tape
drive. The original data remains intact in its current location. The backup data is a copy kept for the sole
purpose of restoring data should the original file be lost or damaged.
Backups in Data Protector Express are performed by running backup jobs. You can create one or more
backup jobs depending on what your particular backup needs are. Backup jobs copy selected files
from file servers, application servers, and user PCs to various storage media, such as tapes, writable
CD or DVD media, or virtual tape media (disk). These backups are stored to preserve a copy of the file
or folder for future use.
