 Restoring or Checking a Backup with a Succeeding Medium 

Use

You specify the next medium from which reading in the backup is to continue. The reply to this command gives you information about the import of the backup. However, you see this information only if the backup has been imported completely, or if the backup was interrupted. This command may, therefore, take a long time to execute.

Prerequisites

You have the DBM operator authorization Backup.

You have executed the command for restoring a database instance. The procedure was interrupted, because all backup data has been read from one backup medium.

Syntax

recover_replace <medium> [ExternalBackupID <ext_backup_ID>] [<loc> [<nnn>]]

<medium>

Medium from which the backup is to be read.
When restoring a backup made on several media at the same time, you must enter the name of the group of parallel backup media here.

Options

ExternalBackupID <external_backup_ID>

To restore a backup created with an external backup tool, enter a backup ID name here that the external backup tool can recognize as the backup.

<loc>

Name of the device/the file in which the backup to be restored is stored.
Operating system functions must be able to address the device/file using <loc>.

<nnn>

Actual backup version on the backup medium that is to be read; relevant only for a backup medium of the type FILE.

It is vital you follow the current media naming conventions (see Defining or Changing a Backup Medium) to avoid error messages.

In particular, analyze the Returncode reply field, which contains a numeric value supplied by the kernel.

If it is clear from the message number that the recovery was only interrupted, the session must be continued with the continuation command (recover_replace) or terminated (recover_cancel).
