Data storage security system and method of storage online data to secure air-gapped offline multi-storage

A method for securely storing data in a data storage security system, the method comprising:

• performing a process for a data storage security system comprising:
• activating a transitory R/W storage unit and connecting the transitory R/W storage unit to an outside world via a first air gap connection to retrieve data;
• deactivating and disconnecting the transitory R/W storage unit from the outside world via the first air gap connection;
• connecting the transitory R/W storage unit via a second air gap connection to one of a plurality of cold data storage units through a data unit and an immutable PLC electronic switch;
• transferring data to the one of the plurality of cold data storage units, followed by deactivating and disconnecting the transitory R/W storage unit from the one of the plurality of cold data storage units via the second air gap connection;
• repeat the process sequentially for remaining ones of the plurality of cold data storage units, ensuring that only one of the plurality of cold data storage units is active at any given time while the remaining ones of the plurality of cold data storage units remain turned off and immutable.
