SEP sesam supports system state data backup and uses Microsoft Volume Shadow Copy Service (VSS) to back up system state components. These components include core files and registry settings and are related to various aspects of Windows operating system.
In the event of a system crash or corruption you can use the system state backup to restore Windows system settings and other critical system related components, such as registry, boot file, Active Directory etc. This way you do not have to manually reconfigure Windows back to its original state before the crash or corruption.
Up until SEP sesam version 4.4.3, the system state backup was known and selectable under the name System_recovery. This option is now renamed to System_state without change in functionality.
|System state backup may not be sufficient to recover your system after a failure and is not a replacement for a disaster recovery solution. To prepare your system for disaster recovery, use SEP sesam BSR Pro to create a boot image on the client which may be used to recover the client system.|
System state backup type
The Windows system state is a selectable backup type which provides backup of all system state components as a unit. Note that system state elements are machine-specific and depend on each operating system installation version and configuration. SEP sesam allows for dynamic discovery of existing system state elements and backup.
At a minimum, the following components are backed up:
- System state data
- Registry, COM+ class registration database, boot and system files, DFS namespaces/replications
- A domain controller system state
- Active Directory Domain Services, Windows Registry, COM+ database, SYSVOL directory
- System services components
- Background Intelligent Transfer Service (BITS), Cluster Service information (cluster node only), Dynamic Host Configuration Protocol (DHCP), Microsoft Internet Information Services (IIS) meta-directory, Removable Storage Management Database (RSM), Remote Storage Service, Terminal Server Licensing, Windows Internet Name Service (WINS), Windows Management Instrumentation (WMI)
Make sure that the following conditions are met when backing up system state data:
- You must be an administrator or a backup operator to back up system state information.
- On the SEP sesam Server, run a test to ensure that the SEP sesam file system backup of the corresponding client is working and that data can be restored.
Creating a system state backup task
Configuring a system state backup involves creating a System state backup task for your Windows client, setting up a backup schedule (specifying when you want to back up your data) and linking the schedule to a backup event (specifying how to back up the data and where to back it up to). For general information on backup configuration and prerequisites, see Standard Backup Procedure. This section deals only with system state backup specific information.
- In the Main Selection -> Tasks -> By clients, select your Windows client then click New backup task. The New backup task window appears.
- Now specify the Source: click the browse button and select System state. This specifies your system state data as the source and sets the System_state backup type and the task name automatically.
- Click OK to create the task.
You can group your backup tasks to task groups. For details, see Adding a Task to the Task Group. The final step in the backup configuration is creating a new backup event. For general information, see Creating a backup event. Then run your system state backup.
