This invention is for a relatively loose recovery of data still not backed up at the time of a failure by later inputting it. A recovery method of recovering processes at a data center when a failure occurs at another data center during execution of the process, has a step of transmitting data at a first data center normally used to a second data center at a predetermined interval and backup at the second data center; a step of, when the first data center breaks down, selecting an information processing apparatus of which recovery time including a time for inputting data not backed up satisfies a requested recovery time, from the second data center; and a step of deploying applications used at the first data center in the selected information apparatus and recovering the data from the backup.
