Abstract
In some examples, a method for encoding and storing data blocks of a data file on multiple file servers is described. The method may include selecting a data clip size S, selecting a number N of data clips to include in each data block, and dividing the data file into data blocks each having data size (S×N). The method may also include, for each data block, dividing the data block into N data clips, generating a random number R where 1≤R≤N, selecting a number K of redundant data clips where N≤K<2^N, encoding K data clips using random linear coding by XORing R data clips K times, and storing the K encoded data clips on the multiple file servers.
