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.

Perform a warm restore

To perform a warm restore with ontape, the database server must operate in online or quiescent mode.

You must run the ontape command as the owner of the database server: user informix or root for a standard installation, or the owner of the non-root installation. The owner of the database server for the restore must be the same as the owner of the database server for the backup.

To restore selected storage spaces, run the ontape command, with the options that the following example shows:

ontape -r -D dbspace1 dbspace2

You cannot restore critical dbspaces during a warm restore; you must restore them as part of a cold restore, described in Restore the whole system.

During the restore, ontape prompts you to mount tapes with the appropriate backup files.

At the end of the warm restore, the storage spaces that were down go online.
