发明名称 METHOD AND SYSTEM FOR STORING FILES
摘要 The present invention presents a method and a system of indexing, storing and retrieving data to and from multiple, remote and connected data sources over internet or intranet. Files are shredded into fixed number of strips using a defined pattern (shredding algorithm) and distributed randomly amongst the storage data sources (storage nodes). A unique index is maintained for each file and its strips along with corresponding storage nodes in a central file-storage database. On demand to retrieve a file, file-storage database is looked up for all relevant strips and storage nodes containing them. These file strips are then collected from all storage nodes and dressed back according to a defined anti-pattern (dressing algorithm) to the pattern used for shredding them. Failover control for storage nodes can be achieved by replicating each strip for a fixed number of storage nodes (replication factor). In case a storage node is not available, the next storage node containing the same strip can be used to get the strip back.
