Data Recovery conclusions Because the on-site environment is well preserved after a fault occurs, no related dangerous operations are used, which is of great help to the later data recovery. Although many technical bottlenecks have been encountered during the entire data recovery process, they have all been resolved one by one. In the end, the entire dat
