Method for providing fault tolerance to multiple servers
View Patent ↗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.
1. A method for providing fault tolerance to multiple computer servers, said method comprising:
utilizing t backup computer servers to backup data from a plurality of active computer servers in order to tolerate up to t faults in said active computer servers;
categorizing data from said plurality of active computer servers under their respective one of plurality of data structures; and
in response to any access to data within one or more of said plurality of active computer servers, performing backup operations on said accessed data in said t backup computer servers according to their data structures, wherein similar data structures are grouped under their respective fusible data structure within said t backup computer servers.
2. A computer recordable type medium having a computer program product for providing fault tolerance to multiple computer servers, said computer recordable type medium comprising:
instructions for utilizing t backup computer servers to backup data from a plurality of active computer servers in order to tolerate up to t faults in said active computer servers;
instructions for categorizing data from said plurality of active computer servers under their respective one of plurality of data structures; and
instructions for, in response to any access to data within one or more of said plurality of active computer servers, performing backup operations on said accessed data in said t backup computer servers according to their data structures, wherein similar data structures are grouped under their respective fusible data structure within said t backup computer servers.
3. An apparatus for providing fault tolerance to multiple computer servers, said apparatus comprising:
t backup computer servers for backing up data from a plurality of active computer servers in order to tolerate up to t faults in said active computer servers;
means for categorizing data from said plurality of active computer servers under their respective one of plurality of data structures; and
means for, in response to any access to data within one or more of said plurality of active computer servers, performing backup operations on said accessed data in said t backup computer servers according to their data structures, wherein similar data structures are grouped under their respective fusible data structure within said t backup computer servers.
