4.1. How to Archive and Restore TPM keys

The Archive and Restore functionality is used to back up and restore all user credentials (login and

encryption information) stored in the Trusted Platform Module (TPM). A backup of this data is

important when re-provisioning a computer or for restoring data in the case of hardware failure. In this

case, you can simply restore all of your credentials to your new computer from a saved archive file. It is

recommended to create an archive periodically to prevent credential/data loss.

Examples of when a TPM archive would be useful are:

• The TPM was cleared - If your TPM is cleared, intentionally or accidentally, you can recover keys

and data.

• The motherboard/TPM was replaced - In the case of hardware failure; credentials can be

migrated to the new TPM.

• You transfer to another computer - If you move to a new computer, you can restore your old

credentials to the new computer and protect them with the TPM.

• You re-install your operating system – TPM keys and data will be lost if you re-install your

operating system.

To archive keys for each user:

1. Have the user login:

2. Click on the “Archive and Restore” tab at the left.

3. Click the “Archive” button; this will open an Archive wizard.

4. Select the checkbox for the data you wish to back up, “TPM Data”.

5. You will be prompted for the TPM Owner Password, and Master Password if applicable.

6. You will be prompted to create a new archive password. This password must be entered later to

restore from the archive.

7. A success screen will be displayed, however if no keys have been generated to back up, you will

be shown an error message.

To restore keys for a user:

1. Ensure the target machine is running the same version of ESC and has a TPM that is activated,

enabled, and owned.

2. Have the user login:

3. Click the “Restore” button; this will open a Restoration wizard.

4. Click browse to select the archive you wish to restore.

Click next

6. Select the “TPM Data” and click next

7. Enter the new TPM Owner Password, and Master Password if applicable.
