Image processing apparatus, backup storage method, and non-transitory computer-readable recording medium

A method for storing firmware as a backup in an image processing apparatus, the image processing apparatus comprising:

• a first storage section that stores multiple firmware to be started up in stages;
• a second storage section that stores, as a backup, a firmware selected from among the multiple firmware;
• and
• a hardware processor that detects tampering with each of the multiple firmware stored in the first storage section and, upon detection of tampering with a firmware, restores the tampered firmware using the firmware stored in the second storage section, wherein
• the method comprises:
• selecting, from among the multiple firmware, firmware to be stored as a backup in the second storage section in accordance with an apparatus state;
• and
• changing firmware stored as backup in the second storage section according to the selection result.

A non-transitory computer-readable recording medium storing a program executed in an image processing apparatus, the image processing apparatus comprising:

• a first storage section that stores multiple firmware to be started up in stages;
• a second storage section that stores, as a backup, a firmware selected from among the multiple firmware;
• and
• a hardware processor that detects tampering with each of the multiple firmware stored in the first storage section and, upon detection of tampering with a firmware, restores the tampered firmware using the firmware stored in the second storage section, wherein
• the program causes the hardware processor to perform:
• selecting, from among the multiple firmware, firmware to be stored as a backup in the second storage section in accordance with an apparatus state;
• and
• changing firmware stored as backup in the second storage section according to the selection result.
