摘要： An information processing system retains one or more files utilized by an external apparatus, each of which is made up of a plurality of chunks, in a manner that the chunks making up each of the files are distributed. The information processing system includes a plurality of chunk servers, each storing chunks, and one master server communicatively coupled thereto. The master server retains a file name of a file, chunk IDs indicating chunks making up the file, and chunk IDs indicating chunk servers storing the chunks. When a snapshot taking request for a file is received, the master server identifies chunks included in the file from the file name and the chunk IDs to instruct the chunk servers having these chunks to take a differential snapshot of each of the chunks with the use of a differential snapshot function included in a local file system of each of the chunk servers.

摘要： Provided is a computer system in which a plurality of virtual machines operate on a host computer. The host computer has a time subtraction table for storing the time subtraction with the respective virtual machines, and a log collection unit for collecting the logs of the respective virtual machines. The log contains a time stamp which shows at least the log output time. The log collection unit corrects the time stamp of the logs collected from the respective virtual machines based on the time subtraction stored in the time subtraction table. According to this computer system, the logs of the virtual machines operating in a time series that is different from the time series of the host computer can be collected upon integrating the time series of the virtual machines and the host computer.
