The backup procedure creates a copy of the QCL application in execution and a dump of the retentive data, as files saved in the NAND mass storage. The files created have the following names:

• applic.qcy identifies the file containing the QCL application (CPU)
• appdat.qcy identifies the file containing the retentive data of the QCL application

The procedure performs the following steps:

• Check the presence of the QCL application.
• Create and write in NAND the QCL application backup file: applic.qcy.
• Check the presence and validity of retentive data of the QCL application.
• Create and write in NAND the retentive data backup file of the QCL application: appdat.qcy.
• Procedure end and system reboot.
