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.

Compress row data

Compressing row data can make backing up and restoring data more efficient.

Compressing row data before backing it up can improve the speed of backing up and restoring and requires less backup media. A smaller size of data results in the following advantages over uncompressed data during backup and restore:

Backing up is quicker.
Restoring is quicker.
The logical logs are smaller.
The backup image is smaller.

Using an external compression utility to compress a backup image of compressed row data might not reduce the size of the backup image, because already compressed data usually cannot be further compressed. In some cases, the size of the backup image of compressed row data might be larger than the size of the backup image that was compressed by an external utility.
