Overview
– You must also create a backup of the TPM content. To do this, follow
the third party manufacturer's instructions. Without this backup, if the
TPM or the system board is faulty you will not be able to access your
data.
– If a failure occurs, please inform your service about the TPM
activation before it takes any action, and be prepared to provide them
with your backup copies of the TPM content.
