Copying from a SnapVault volume to a local tape

You can use SnapMirror to back up a SnapVault volume to tape. The backup on the tape can later be used to restore data to the SnapVault volume.

Steps

1. At the SnapVault secondary storage system, load the tape into a local attached tape device.
2. At the SnapVault secondary storage system, start the data transfer to tape by entering the following command: snapmirror store sv_volume dest_tapedevices

   sv_volume is the volume you are copying.

   dest_tapedevices is a comma-separated list of tape devices to which you are copying the volume.

   SnapMirror starts transferring data to tape. This command creates a baseline transfer. If you have to use more than one tape, SnapMirror prompts you for another tape.

3. If SnapMirror prompts you for another tape, add another tape to the drive, and continue transfer of data to tape by entering the following command: snapmirror use dest_tapedevices tape_drive

   dest_tapedevices is a comma-separated list of tape devices to which you are copying the volume.

   tape_drive is the drive holding the new tape you supplied.

   Note: The snapmirror use command does not support copying qtrees from tape. If you specify a qtree path as the source or destination, SnapMirror returns an error message.

4. Repeat the previous step until SnapMirror finishes copying the volume to tape.
5. If the volume on the SnapVault secondary system that you backed up ever needs to be restored, use the backup on the tape to restore the volume.
