Abstract: A backup/recovery system and methodology that provides seamless networking. According to the invention, backup/recovery system is suitable for a network. The backup/recovery system includes a server part and at least one client part for storing at least one incremental recovery point. The at least one client part sends at least one incremental recovery point to the server part. The at least one incremental recovery point instantaneously stores data that has been changed, so as to economize the use of storage space occupied by the backup data, and enhance the efficiency of recovery operation.

Abstract: A backup/recovery system is provided which has ability to back up and restore every type of recovery point to external storage media. A backup method is also provided, suitable for a computer system including a hard disk and at least one recovery point stored therein, the recovery points holding data being changed within said hard disk, The backup method includes selecting a predetermined recovery point, writing data contained in a base recovery point into a external storage media, said base recovery point corresponding to a status of said hard disk, and writing data contained in said predetermined recovery point into said external storage media.
