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.
Determine failure severityAfter you determine your recovery goals, create your recovery plan. The plan should include recovery goals for multiple levels of failure.

Determine failure severity

After you determine your recovery goals, create your recovery plan. The plan should include recovery goals for multiple levels of failure.

The following table shows recovery plans for failures with amounts of lost data.

Table 1. Sample recovery plans
Failure severity	Data loss	Suggested recovery plan
Small	Noncritical data is lost.	Restore of the data can wait until a nonpeak time. Use a warm restore.
Medium	The data that is lost is critical for your business but does not reside in a critical dbspace.	Perform a warm restore of this data as soon as possible.
Large	Critical dbspaces are lost.	Use a mixed restore to restore the critical data right away and a warm restore to restore noncritical data during off-peak hours.
Disaster	All data is lost.	Perform a cold or mixed restore as soon as possible.
