Restoring or Checking a Backup with a Succeeding Medium
Use
You specify the next medium from which reading in the
backup is to continue. As a reply to this command, you receive the information about the import of the backup. The output is, however, only given when the backup has been completely read in or is 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. |
Options
ExternalBackupID <external_backup_ID> |
To restore a backup created with an external backup tool, enter a backup ID name here with which the external backup tool will recognize the backup. |
<loc> |
Name of the device/the file in which the backup to be restored is stored. |
<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.Reply
