DEFINITION

Classification: 714/13

Prepared backup processor (e.g., initializing cold backup) or updating backup processor (e.g., by checkpoint message):

(under subclass 10) Subject matter further including means or steps for readying a backup processor or digital data processing system to replace a failed primary processor or digital data processing system, or to receive recent processing result(s) from a backup processor or digital data processing system that may be relied upon.

(1) Note. Classification here allows for the backup processor or digital data processing system to be performing operations unrelated to backup operation before or after failure of the primary processor or digital data processing systems.
