ABSTRACT:
A method for providing fault tolerance to multiple computer servers is disclosed. Basically, t backup computer servers are utilized to back up data from multiple active computer servers such that up to t faults can be tolerated. Data from the active computer servers are categorized under their respective data structure accordingly. In response to any access to data within one or more of the active computer servers, backup operations are performed on the accessed data in the t backup computer servers according to their data structures such that data with similar data structures are grouped under their respective fusible data structure within the t backup computer servers.
