11 Select one or more check boxes based on what you want to recover.
Options Description
Escrow
• Recover oine-generated keys that could not be escrowed to the
Dell Server.
• If a hard drive fails while the user is oine from the network, use
alternate boot media to recover data and non-escrowed keys from
the computer.
Decrypt Point the recovery tool to a directory that contains encrypted les to
decrypt.
NOTE:
As a best practice, decrypt copies of the les, not originals, in
case corruption occurs.
Optionally, if tampering has occurred, select one or both of these
options (see below for details):
• Tamper check - checks for tampered les but does not decrypt
them.
• Tamper check and Force decrypt even if tampered - checks for
tampered les and if the wrapper of a protected Oce document
was tampered with, Data Guardian repairs the wrapper and
decrypts the Oce document.
Tamper check Detects les that have been tampered with and logs them or noties
you. Logs the author that tampered with the le. It does not decrypt
the les.
Force decrypt even if tampered To select this option, you must also select Tamper check.
If an unauthorized person tampered with the wrapper of a protected
Oce document, such as the cover page, either in the cloud or on a
device that does not have Data Guardian, select this option to repair
the wrapper and to force decryption of the protected Oce le.
NOTE:
If someone tampered with the encrypted Oce .xen le within
the wrapper, the le cannot be recovered.
Each protected Oce document has a hidden watermark that contains a history of the original user and computer name and any
other computer name that modied the le. By default, the recovery tool checks the hidden watermarks and adds a text le with a list
of all authors to a HiddenWatermark folder in the logs.
12 After selections are complete, click Scan.
The Log area displays:
• Folders found and scanned within the selected source
• Whether decryption, per le, was successful or failed
• The name of the last author of a le
