deviceSpecifier

Purpose

Use the deviceSpecifier subclause to specify the type of storage for a backup.

Semantics

Syntax Element Description
DISK Specifies a disk storage device (see Example 4-16).
media_device Specifies a sequential I/O device or access method for storage (see Example 4-15).

The media_device variable specifies a case-insensitive name for a media manager. The syntax and semantics of sequential I/O device types are platform-specific. The most common value is sbt or sbt_tape (which are synonymous values).

Note: RMAN stores the value sbt in the recovery catalog as sbt_tape for backward compatibility.
