Existing GRID infrastructures rely on explicit user instructions in order to replicate files for the purposes of resiliency. This human-intensive process is inefficient, error prone and, more importantly, makes file replication in GRIDs a cumbersome task. To address this problem, the authors introduce FlexFS - a fully automated file-system framework that seamlessly plugs into existing GRID structures providing automated file replication and transparent-to-user resilience. FlexFS breaks apart files into blocks and injects resilient information into these blocks through the use of Forward Erasure Correction (FEC) codes.
