Replica Checking for Reliability). We first explained the theoretical basis of PRCR
that the data reliability can be predicted and ensured by regularly checking the data
files and recovering any data loss. Then we described the structure and working pro-
cess of PRCR in detail. Afterward, in order to maintain the large amount of data files
in the Cloud properly as well as optimize the function of PRCR, two algorithms for
supporting the data reliability assurance and optimizing the utilization of PRCR re-
sources were presented respectively.
