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 recovery strategyBefore you use ON-Bar or ontape, plan your recovery goals.
Schedule backupsYou recovery strategy should include a schedule of backups. Tailor your backup plan to the requirements of your system. The more often the data changes and the more important it is, the more frequently you need to back it up.

Schedule backups

You recovery strategy should include a schedule of backups. Tailor your backup plan to the requirements of your system. The more often the data changes and the more important it is, the more frequently you need to back it up.

Your backup plan should also specify the backup level.

The following table shows a sample backup plan for a small or medium-sized system.

Table 1. Sample backup plan
Backup level	Backup schedule
Complete backup (level-0)	Saturday at 6 p.m.
Incremental backup (level-1)	Tuesday and Thursday at 6 p.m.
Incremental backup (level-2)	Daily at 6 p.m.
Level-0 backup of storage spaces that are updated frequently	Hourly

Important: Perform a level-0 backup after you change the physical schema, such as adding a chunk to a storage space. (See Preparing to back up data.)
