To initiate a checkpoint in VMS, ready the tape and issue the ckpdb command with the –m option. For more information about the ckpdb command, see the Command Reference Guide.

The backup system uses the VMS BACKUP utility to create checkpoints. This utility allows you to back up on multiple tapes. The program asks for more tapes as needed during the checkpoint procedure.

The backup uses the following command in the script:

II_SYSTEM:[INGRES.FILES.CHECKPOINT]CKP_TO_TAPE.COM

You can tailor this command to meet your needs (for example, to meet local conventions such as tape labeling).

For detailed information on backing up to tape, see your VMS backup documentation.
