Emergency Recovery File Back Up Procedures 
The Emergency Recovery Token (SPEmRecToken.xml) must be saved or moved to a removable 
media (floppy, USB drive, CDR, flash media, etc).  Once this is done, the removable media should 
be stored in a secure location.  DO NOT LEAVE ANY COPIES of the Emergency Recovery Token 
on the hard drive or within any hard drive image backups.  If a copy of the Emergency Recovery 
Token remains on the system, it could be used to compromise the Trusted Platform Module and 
platform.  
After completing the Infineon Security Platform User Initialization Wizard, a copy of the 
Emergency Recovery Archive (SPEmRecArchive.xml) should be copied to a removable media 
and stored in a secure location.  This procedure should be repeated after any password changes or 
the addition of a new user. 
Hard Drive Image Backup Procedures 
To allow for emergency recovery from a hard drive failure, frequent images of the hard drive 
should be created and stored in a secure location.  In the event of a hard drive failure, the latest 
image can be restored to a new hard drive and access to the encrypted data may be re-established.   
 
NOTE 
All encrypted and unencrypted data that was added after the last image was created will be lost. 
Clear Text Backup (Optional) 
It is recommended that system owners follow the Hard Drive Image Backup Procedures.  To 
backup select files without creating a drive image, files can be moved from secured programs or 
drive letters to an unencrypted directory.  The unencrypted (clear text) files may then be backed up 
to a removable media and stored in a secure location.  The advantage of the clear text backup is that 
no TPM key is required to restore the data.  This option is not recommended because the data is 
exposed during backup and restore.
