The Heart
The Heart holds a backup of the system which can be used to:
·
Clone the system onto a replacement CPU Board if the original requires replacement.
·
Return the system to an earlier state.
All aspects of the system are recorded in the backup including firmware, fault logs,
configuration and all changes made to the point at which the backup was taken.
The Heart is implemented using an SD card Mass Storage device fitted to the CPU Board.
The formatting of the card is such that it is not readable in a PC. There are
no user files accessible on the card.
Backups are created and written to the Heart periodically, usually at 00:30am but this can
be changed if required. Backups can also be created and saved on demand.
For more information see the User Interface Handbook 667/HU/46000/000.
