Patent ID: 8775375

Claim:
A multi-cluster synchronization system, comprising: a first cluster including a first cluster-internal network, the first cluster further including a first structured information repository and a first object storage, wherein the first structured information repository contains metadata corresponding to stored information objects in the first object storage, and wherein the first structured information repository and the first object storage are coupled via the first cluster-internal network; an intercluster network coupling the first cluster and a remote cluster; and an intercluster repository synchronizer including a compression module that selectively compresses multiple objects from the first object storage into a single file and identifies one or more files to compress and transmit to the remote cluster in compressed form, wherein the compression module further includes a programmable threshold, and wherein the compression module selectively compresses an object from the first object storage if a ratio of a compressed size of the object to a non-compressed size of the object exceeds the programmable threshold.
