Media Agent

A process that controls reading from and writing to a device, which reads from or writes to a medium (typically a tape).

During a backup session, the Media Agent receives data from the Disk Agent and sends it to the device for writing it to the medium. During a restore session, the Media Agent locates data on the backup medium and sends it to the Disk Agent. The Disk Agent then writes the data to the disk. The Media Agent also manages the robotics control of a library.

MAPI (MS Exchange specific term) The MAPI (Messaging Application Programming Interface) is the programming interface that lets applications and messaging clients interact with messaging and information systems.

media allocation policy

Determines in which sequence media are used for backup. The Strict allocation policy directs Data Protector to prompt for a specific medium. The Loose policy directs Data Protector to prompt for any suitable medium. The

Formatted First policy directs Data Protector to give preference to unknown media, even if unprotected media are available in the library.

media condition

The quality of a medium as derived from the media condition factors. Heavy usage and age result in an increased number of read and write errors with tape media. Media need to be replaced when they are marked as POOR.

media condition factors

media ID

A unique identifier assigned to a medium by Data Protector.
