摘要
A computer-implemented method for layered storage of enterprise data comprises: - receiving from one or more virtual machines (227, 228; 311, 312, 314) data blocks (121); - de-duplicating the data blocks (121) per hypervisor; - storing de-duplicated data blocks (121) in a local cache memory (102); - time-based grouping the data blocks (121) into data containers (151, 152); - dividing each data container (151, 152) in X fixed length mega-blocks; - for each data container (151, 152) applying erasure encoding to the X fixed length mega-blocks to thereby generate Y fixed length mega-blocks with redundant data, Y being larger than X; and - distributed storing the Y fixed length mega-blocks across multiple backend storage systems (226; 403; 503).
