Backup and Restore GuideThe HCL OneDB™ Backup and Restore Guide describes how to use the HCL® OneDB® ON-Bar and ontape utilities to back up and restore database server data. These utilities enable you to recover your databases after data is lost or becomes corrupted due to hardware or software failure or accident.

Label tapes created with ontape

When you label tapes created with the ontape utility, the label must include the following information:

Backup level
Date and time
Tape number that ontape provides

The following example shows what a label can look like:

Level 1: Wed Nov 27, 2001 20:45 Tape # 3 of 5

Each backup begins with its first tape reel numbered 1. You number each additional tape reel consecutively thereafter. You number a five-tape backup 1 through 5. (Of course, it is possible that you could not know that it is a five-tape backup until it is finished.)
