Backup and Restore Security Platform Data

Security Platform Backup includes all data required in case of emergency. After a hardware or storage media failure or a Trusted Platform Module failure, Security Platform Restoration reestablishes access to Security Platform Features for all users.

In addition you can backup and restore your Personal Secure Drive data. Data from other applications using the Security Platform Solution (e.g. Secure e-mail) is not included in Security Platform backup.

In server mode Backup and Restoration of user credentials and settings is handled by Trusted Computing Management Server, except Backup and Restoration of Personal Secure Drive (PSD) image files.
The update of user credentials and settings which is handled by Trusted Computing Management Server is also based on Backup and Restore.

Backup Scope

Security Platform backup comprises the following data:

Security Platform Credentials and Settings
Backup Contents	A copy of the user-specific credentials and settings which are stored on the Security Platform.
Purpose	Restoration of user-specific credentials and settings after a hardware or storage media failure. Otherwise users could not access Security Platform Features anymore and user data would be lost.
Archives	Automatically written Backup Archive ("System Backup Archive", e.g. file SPSystemBackup.xml and folder SPSystemBackup): Set up by Security Platform Administrator. Contains credentials and settings of all Security Platform Users (for one or multiple Security Platform computers). Also contains computer identification and user identification, which are used to match computers and users during the restoration process. Manually written Backup Archive (e.g. SPBackupArchive.xml): Created by Security Platform User. Contains credentials and settings of one Security Platform User (for one Security Platform computer). Also contains computer identification and user identification, which are used to match computer and user during the restoration process.
Emergency Recovery
Backup Contents	All Security Platform Basic User Keys, encrypted specifically for Emergency Recovery.
Purpose	Re-encryption of all Basic User Keys after a Trusted Platform Module failure. In this case a new Security Platform has to be set up and a new owner is created. Emergency Recovery allows the re-encryption of Basic User Keys from the old owner to the new one. Otherwise users could not access Security Platform Features anymore and user data would be lost.
Archives	Emergency Recovery data for all users is included in automatically written Backup Archives. It is also included for the concerned user in manually written Backup Archives, if Automatic Backup has already been configured at the time the manual backup is performed. Emergency Recovery Token (e.g. SPEmRecToken.xml) or combined Emergency Recovery/Password Reset Token (e.g. SpToken_<PCName>.xml): Created by Security Platform Administrator. Is required for a restoration of Emergency Recovery data.
Personal Secure Drive
Backup Contents	A copy of the PSD credentials, configuration settings and encrypted data.
Purpose	Restoration of PSD encrypted data and configuration settings after a hardware or storage media failure. Otherwise users could not decrypt their PSD data anymore. Notes: In contrast to the PSD Backup, standard hard disk backup tools produce unencrypted backups. If the PSD credentials are lost and no credential backup is available, but the PSD image file or backup image file is available, this data can be recovered via Personal Secure Drive Recovery.
Archives	PSD configuration settings are included in both automatically written Backup Archives and manually written Backup Archives. PSD backup file (e.g. SpPSDBackup.fsb): A backup copy of the PSD image file may be created during a Security Platform User's manual backup.
