Digipass Plug-In for SBR Administrator Reference Backup and Recovery 6.1.3.2 Write to ODBC Database Back up the database using the database's backup utility. 6.1.3.3 Write to Windows Event Log By default, Event Log entries are written to the Application log. However, you can configure the entries to be written to another log. Check the audit configuration if you are unsure. Important Note The Event Log may be configured with a maximum size. When this size is reached, the oldest entries may be overwritten by new ones. To check this, view the Properties of the log in the Event Viewer. If older entries will be overwritten, you will need to archive them before that occurs. To archive an Event Log: 1. Select Start -> Settings -> Control Panel. 2. Double-click on Administrative Tools. 3. Double-click on Event Viewer. 4. Right-click on Application (or the correct log, if not Application). 5. Click on Save log file as... 6. Select a path and enter a filename. 7. Select a file format from the Type drop down list. 8. Click on the Save button. Note The Audit Log data is not required for system recovery purposes. 6.1.4 DPX files The DPX files are normally provided on a floppy disk, which can be stored securely as a backup. If you prefer another method of archive, copy the files to your preferred location. It is important to keep the DPX file transport keys secure and preferably in a separate location to the DPX files themselves. 6.1.5 Active Directory 6.1.5.1 Cold Backup In many cases the SBR Plug-In will belong to an Active Directory domain that includes several Domain Controllers. Replication should automatically occur between Domain Controllers, providing simple data backup. It is highly recommended, however, that you perform a 'cold' backup of the System State Data, which includes the Active Directory repository. This will allow recovery if data is corrupted and then replicated. For more information about backing up and restoring System © 2006 VASCO Data Security Inc. 70
Digipass Plug-In for SBR Administrator Reference Backup and Recovery State Data, refer to Windows Help on your Domain Controller and enter 'backing up data, System State data' in the index tab. In particular, this should be performed on the Digipass Configuration Domain and any other Domains containing Digipass User accounts and/or Digipass records. 6.1.6 ODBC and Embedded Database 6.1.6.1 Data Source Settings If you have performed some adjustments to the ODBC Data Source (DSN) that are important to keep, make sure that you have a readout of the settings. 6.1.6.2 Backup Strategies Warm Backup A 'warm' backup of the disk containing the database used by the SBR Plug-In via a RAID hardware configuration or server mirroring is a favorable backup method. It is both entirely up to date and incurs no downtime if a single disk failure occurs. This method requires either software RAID, or for better performance a hardware RAID configuration. Another technique that achieves the same effect is the 'shadow database'. However, it is still recommended to take a cold backup at intervals, as there is a possibility that a database corruption could be mirrored/shadowed under some circumstances. Cold Backup A 'cold' backup of the database allows administrators to implement a duplicate database as a safeguard on a regular basis. Generally speaking there are two methods that can be used to perform a cold backup: Backup Utility The first option is to use the vendor-specific backup utility that allows the contents of the database to backed up to a file or device while the system is running. Such a utility is provided with the embedded database PostgreSQL (see below). Shut Down and Copy the Database File The second option involves stopping the database server and any connecting server processes and copying the database files. However, this is only possible where the database vendor recommends this approach. Normally this is only appropriate if the database is contained in a single operating system file. Replicated Copy If replication has been configured between databases, a replicated copy can be used as a backup. However, it is still recommended to take a cold backup at intervals. © 2006 VASCO Data Security Inc. 71
