# deviceSpecifier

Syntax

deviceSpecifier::=

Description of the illustration devicespecifier.gif

Purpose

A subclause specifying the type of storage for a backup or copy.

Keywords and Parameters

Syntax Element | Description
--- | ---
`DISK` | Specifies disk storage device.
`'media_device'` | Specifies a sequential I/O device or access method for storage. The syntax and semantics of sequential I/O device types are platform-specific. Example values are `sbt` and `sbt_tape` (with or without quotes). These values are synonymous. The `media_device` variable specifies a media manager. Media device names are case insensitive. The `sbt` variable is legal as input, but RMAN output always displays its synonym `sbt_tape`. It is stored in the catalog as `sbt_tape` for backward compatibility.

Examples

Allocating a Tape Channel: Example This example allocates a maintenance channel for a media management device:

    ALLOCATE CHANNEL FOR MAINTENANCE DEVICE TYPE sbt;

Backing Up to Disk: Example This example backs up the database to disk:

    BACKUP DEVICE TYPE DISK DATABASE;

Restoring from Tape: Example This example restores archived logs from tape:

    RESTORE DEVICE TYPE sbt ARCHIVELOG ALL;
