Abstract

Se proporciona un sistema de archivos distribuidos y un sistema de respaldo de datos para el sistema de archivos distribuidos. El sistema incluye un: FLR principal, un primer FAC, un FAS principal, y por lo menos un primer FLR inactivo y un primer FAS alternativo; un subsistema distribuido de respaldo consta de un FLR de respaldo, un segundo FAC, un FAS de respaldo y por lo menos un segundo FLR inactivo y un segundo FAS alternativo; por lo menos el primer FLR inactivo y por lo menos el segundo FLR inactivo de emplean para respaldar los metadatos en el FLR de respaldo; el primer FAS alternativo y el segundo FAS alternativo se emplean para sincronizarse con el FAS principal y el FAS de respaldo para realizar operaciones de escritura en datos reales actuales cuando el primer FAC o el segundo FAC reciben comandos de operación de escritura de datos. La solución mejora la fiabilidad y practicidad del sistema.
