Restoring from One Medium

The simplest kind of restoring is that from one medium only. The restore procedure corresponds to the save procedure.

Interactive Procedure:

1. Select the restore action.

2. Select the medium.

3. Check the entries.

4. Start the restore operation.

1. Select the Restore Action (Example: Backup / Restore / Data)

Select one of the restore actions "data", "updated pages" up to "log segment" from the Backup / Restore menu item.

A list of the defined media appears. If no media have been defined so far, they must be defined now. How this can be done is described in Section Backup / Media Manager .

Example of several defined media:

2. Select the Medium

To select the medium from the list of defined media, place the cursor on the desired medium containing the backup and click on the Select button or press the key.

We recommend to select the same medium for the recovery that was used for the backup. In exceptional situations, however, it can be necessary to restore from another medium. For example, the backup had been done to a file that was meanwhile written to tape. In this case, you can restore directly from tape by defining the corresponding tape device as the medium. (Or version files that had been generated for the automatic backup of log segments were written to tape from which they can be restored directly.)

3. Check the Entries

The screen with the selected medium definition is displayed for security reasons. For tapes selected as media, you must now mount the tape to the tape device if this has not been done yet, because otherwise the backup will fail. Then you can confirm the media screen.

Confirm the medium definition with Ok or . The Cancel button can be used to terminate the restore operation.

Data can still be modified, if required, (after pressing the key). The Media Manager, however, does not store these changes as permanent medium definition. For modifications of media definitions, the interrelations described for the Media Manager must be considered (see Section Backup / Media Manager).

Now a screen is displayed showing the content of the label included on the medium to be restored to identify the backup. The label (here "data_a0_a") is displayed for information and must be confirmed.

4. Start the Restore Operation

Start the restore procedure by clicking on the Ok button (or by pressing the key.

CONTROL displays a bar to indicate the progress of the recovery. If the recovery terminates, the result protocol is displayed.

Batch Call:

Syntax:

Example:

xrestore -a SAVEDATA -d mydb -m DAT90

The complete description of the batch calls is included in Section Batch Mode: xbackup / xrestore.

To display the protocol file of the batch call, you can use the Backup / Show Protocol menu function.
