on UNIX or disk drives on Windows systems) and the destinations are specified (tape) devices. During the backup session, Data Protector reads the objects, transfers data through the network, and writes it to the media residing in the devices. The backup specification names the devices to use. It also can specify a media pool. If no media pool is specified, the default media pool is used. A backup specification can be a simple definition of the backup of a disk to a standalone DDS drive, or a complex definition of the backup of 40 large servers to a Silo tape library with eight drives.

Creating a backup specification

What is a backup specification?

A backup specification allows you to group objects that you want to back up in a group with common characteristics, such as scheduling, used devices, type of backup, and backup session options.

How to create a backup specification

You configure a backup specification using the Data Protector user interface. You need to know what you want to back up, how many mirrors you want to create, which media and which devices you want to use for the backup, and optionally, some desired specific behavior for the backup. Data Protector provides default behavior that is suitable for most cases. You can customize backup behavior using Data Protector backup options.

Data Protector can back up a client with all the disks connected to it by discovering the disks at backup time. See Backing up with disk discovery” on page 225.

Selecting backup objects

What is a backup object?

Data Protector uses the term backup object for a backup unit that contains all items selected for backup from one disk volume (logical disk or mount point). The selected items can be any number of files, directories, or the entire disk or mount point.

Additionally, a backup object can be a database entity or a disk image (rawdisk).

A backup object is defined by:

Client name: a hostname of the Data Protector client where the backup object resides.

Mount point: an access point in a directory structure (drive on Windows and mount point on UNIX) on the client where the backup object is located.
