Restore examples: Multiple tape restores

There are different types of multiple tape restores, such as multiple tapes on a single-tape drive, multiple tapes on two single-tape drives, and multiple tapes on a tape library.

Example of restore from multiple tapes on a single-tape drive

Assume you have performed a backup using the following dump command:

dump 0f rst0a /vol/vol

The following command restores the /vol/vol1 volume from the two tapes it took to back it up. You are prompted for the next tape when the first tape is restored.

restore rf rst0a

The following list describes the elements of the command line:
r
Performs a full restore.
f
Specifies that a tape device is supplied in the command line.
rst0a
The restore is done using the rst0a tape device; the restore command prompts for the second tape.

Example of restore from multiple tapes on two single-tape drives

Assume you have performed a backup using the following dump command:

dump 0f rst0a,rst1a /vol/vol1

The first tape is in tape drive 0 and the second tape is in tape drive 1.

The following command restores the /vol/vol1 volume from the two tapes it took to back it up. It uses the tape in the second tape drive when the first tape is restored.

restore rf rst0a,rst1a

The following list describes the elements of the command line:
r
Performs a full restore.
f
Specifies that a tape device is supplied in the command line.
rst0a
The restore is done using the rst0a tape device for the first tape.
rst1a
The restore is done using the rst1a tape device for the second tape.

Example of a restore from multiple tapes on a tape library

Assume you have performed a backup using the following dump command:

dump 0f urst0a,urst0a /vol/vol1

The following command restores the /vol/vol1 volume from the two tapes used to back it up. It unloads the first tape and loads the second tape.

restore rf urst0a,urst0a /vol/vol

The following list describes the elements of the command line:
r
Performs a full restore.
f
Specifies that a tape device is supplied in the command line.
urst0a, urst0a
The tape drive unloads and loads each tape.
