Abstract
A storage service device with a dual controller and a backup method thereof are applicable to provide the same view service to an event-login log and a configuration file of a server. The storage service device includes a first control module, a second control module, a battery unit, a basic input/output system (BIOS), and a backup procedure. Once a power failure occurs to the server, the following backup procedure is performed a hardware interrupt signal is sent to the battery unit, so as to provide an operation power to a first memory module and a second memory module; an index page of the first memory module is synchronized with that of the second memory module; and the updated index pages are recorded into a first flash memory and a second flash memory respectively.
