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.
Overview of backup and restoreThese topics provide an overview of backup and restore concepts. They also provide information about planning for backup and restore operations.
Plan for backup and restoreThese topics describe the planning for backup and restore, for example by planning your recovery strategy and backup system.
Plan a backup system for a production database serverTo plan for adequate backup protection for your data, analyze your database server configuration and activity and the types of backup media available at your installation.
Evaluate logging and transaction activityWhen planning your backup system, also consider logging and transaction activity.

Evaluate logging and transaction activity

When planning your backup system, also consider logging and transaction activity.

The following database server usage requirements affect your decisions about the storage manager and storage devices:

The amount and rate of transaction activity that you expect
The number and size of logical logs
If you need to restore data from a database server with little transaction activity, define many small logical logs. You are less likely to lose data because of infrequent logical-log backups.
How fast the logical-log files fill
Back up log files before they fill so that the database server does not hang.
Database and table logging modes
When you use many nonlogging databases or tables, logical-log backups might become less frequent.
