摘要: The invention discloses a method for deleting multiple layered repetitive data based on distributed file system. comprises the steps that digital fingerprints pending to be written into files are obtained; judged from fingerprint list in global whether or not exist; if exist, metadata information is recorded; do segmented according preset method, and each segment of segments sent corresponding storage nodes. also device efficiency increased, space saved through by technical scheme.
