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, third parties other than an administrator can make backups, which may result in the TPM backup key from being taken away. Since the TPM key can only be backed up once, this will make the TPM key unable to be restored. 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. Manage the password set during the backup so that it is not forgotten. 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. You cannot access the machine while backing up or restoring data in the USB memory. 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 USB memory, press (Settings/Registration) <Preferences> <External Interface> <USB Settings> set <Use MEAP Driver for USB Storage Device> to <Off>. |
If the TPM setting is activated, it may take longer to start the machine. |
Before backing up, make sure that writing is allowed for the memory media connected to the machine. You cannot back up the TPM key for the following cases: The password is incorrect USB memory is not connected Multiple USB storage devices are connected Not enough free space in the connected USB memory TPM key does not exist on the machine Use USB memory that meets the following conditions: Not set to read-only Not partitioned Less than 60 GB capacity Not encrypted For the backup of the TPM key, it is recommended that you use a USB memory with free space of 10 MB or more. Do not connect any other memory media. The data on the machine is backed up on the USB memory after it has been encrypted. You cannot manage or browse the backed up data on the computer. For information on the USB memory that can be used with the machine and how to use it, see Connecting a USB Memory Device. |
Restoring of the TPM key recovers access to the storage device/SRAM that became inaccessible due to TPM chip failure, and does not recover the content of the memory itself. 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. You cannot restore the TPM key for the following cases: USB memory is not connected Multiple USB storage devices are connected A TPM key does not exist on the USB memory The TPM key on the USB memory is not correct The password set during the backup was not entered |
