Info

The backup history shows the incremental backup as the most recent action at the top of the list. When you select it, the Details area expands to display the label information. The backup media available are displayed in the Templates area below. The action information is displayed on the Actions tab page at the very bottom of the Database Studio screen. By double-clicking an entry on this tab page, you can display the corresponding Wizard and the results of the action.
As of version 7.7 you can freeze the data area of a <strong>MaxDB</strong> installation multiple times using internal snapshots. A snapshot can be created in the ONLINE operational state. You can subsequently revert to the dataset of the snapshot and/or delete the snapshot. The database kernel uses the CREATE_SNAPSHOT command to copy the restart page from the second block of the first data volume to a different position. The complete converter is also copied. The original restart record contains a reference to the restart record relevant for the snapshot. The RESTORE_SNAPSHOT command is used to delete the current converter. All blocks that are no longer needed are marked as free. The transaction information that is no longer needed is deleted from the log so that the HISTLOST state is activated. When it is next restarted, the instance works with the data that was frozen using the CREATE_SNAPSHOT command and has now been reactivated. The DROP_SNAPSHOT command deletes the restart record and the converter linked to it that is relevant for the snapshot. FreeBlockManagement (FBM) marks all blocks that are no longer needed as free. <strong>MaxDB</strong> supports multiple snapshots. Operating the instance with multiple snapshots uses more capacity in the data area.
