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.

External backup and restore
External backup and restore overviewAn external backup and restore eliminates the downtime of systems because the backup and restore operations are performed external to the HCL® OneDB® system.

Track an external backup

The database server and ON-Bar do not track external backups. To track the external backup data, use a third-party storage manager or track the data manually.

The following table shows which items we recommend that you track in an external backup. ON-Bar keeps a limited history of external restores.

Table 1. Items to track when you use external backup and restore
Items to track	Examples
Full path names of each chunk file for each backed up storage space	/work/dbspaces/rootdbs (UNIX™) c:\work\dbspaces\rootdbs (Windows™)
Object type	Critical dbspaces, noncritical storage spaces
ins_copyid_hi and ins_copyid_lo	Copy ID that the storage manager assigns to each backup object
Backup date and time	The times that the database server was blocked and unblocked
Backup media	Tape volume number or disk path name
Database server version	The database server version from which the backup was taken.
