Configuring a Backup

A backup is a process that creates a copy of system data on backup media. This copy is stored and kept for future use in case the original is destroyed or corrupted.

Prerequisites	•	You need to have a Disk Agent installed on every system that is to be
		backed up, unless you use NFS (on UNIX) or Network Share Backup
		(on Windows) for backing up these systems.
	•	You need to have at least one backup device configured in the Data
		Protector cell.
	•	You need to have media prepared for your backup.
	•	You need to have appropriate user rights for performing a backup.
Backup	Configuring a backup consists of the following steps:
Configuration	1.	Selecting what to back up - the data sources on the Disk Agent
		clients.
	2.	Selecting where to back up to - the backup devices connected to the
		Media Agent clients.
	3.	Selecting how to back up - backup options.
	4.	Optionally, you can schedule an unattended backup.

You specify these options when creating a backup specification. Refer to “Creating a Backup Specification” on page 154.

At a specified time, Data Protector starts the backup session based on the backup specification. A backup object is any data selected for a backup, such as a disk, a file, a directory, a database, or a part of the database. During the backup session, Data Protector reads the objects, transfers data through the network, and writes them to the media residing in the devices.

The backup specification defines the devices to be used and, optionally, the media pools. If no media pool is specified, the default media pool, which is a part of the device specification, is used.

A backup specification can be as simple as backing up one disk to a standalone DDS drive, or as complex as specifying a backup for 40 large servers to a tape library with 8 drives.
