Before activating the TPM setting, an administrator must confirm that the Administrator password has been changed from its default setting. If the password has not been changed from its default setting, users other than an administrator may be able to obtain the TPM backup key. Since the TPM key can only be backed up once, you cannot restore the TPM key.
Backup the TPM key immediately on to the USB memory after the TPM setting is activated.
For security reasons, you can only backup the TPM key once. Store the USB memory with the backup data in a safe place. Also, write down the password set when backing up and keep it in a safe place.
The security provided by TPM does not guarantee complete protection of the data and hardware. Note that Canon will not be liable for any failure or damages resulting from the use of this mode.
Insert the USB memory straight into the USB port. If the USB memory is inserted in an angle or if you insert a USB memory type not compliant with USB standard, the USB port may be damaged.
Do not remove the USB memory while backing up or restoring data. Doing so may cause damage to the USB memory, USB port, or the data inside of the USB memory. Also if the USB memory is removed when restoring, the machine may be damaged.
To use the USB memory, press [Preferences] (Settings/Registration) → [External Interface] → [USB Settings] → [Off] for <Use MEAP Driver for USB Storage Device>.

Restoring of the TPM key recovers the access to the memory that became inaccessible due to TPM chip failure and does not recover the memory.
If initialization is performed following the steps for "Initializing All Data/Settings," all of the data encrypted by the TPM key is completely erased and the TPM setting becomes inactive.
For the backup of the TPM key, it is recommended that you use a USB memory with free space of 10 MB or more.
You can use the USB memory that is commercially available.
