Methods and apparatus for recovering work of one computer by another computers

A disaster recovery system for recovering a process at a data center when a failure occurs at another data center during execution of the process, comprising:

• a backup forming unit for transmitting data at a first data center normally used by an end user to a second data center at a predetermined time interval and forming a backup of the received data at said second data center;
• an information processing apparatus selecting unit for, when a failure occurs at said first data center, selecting an information processing apparatus whose necessary recovery time including a time taken to input data still not backed up satisfies a predetermined requested recovery time, from information processing apparatuses in said second data center;
• and
• a recovery unit for deploying an application used at said first data center in said selected information apparatus and recovering the data at said first data center from said backup at said selected information processing apparatus.

A storage medium storing a program for making computers function as a disaster recovery system for recovering a process at a data center when a failure occurs at another data center during execution of the process, wherein the computers are made to function as:

• a backup forming unit for transmitting data at a first data center normally used by an end user to a second data center at a predetermined time interval and forming a backup of the received data at said second data center;
• an information processing apparatus selecting unit for, when a failure occurs at said first data center, selecting an information processing apparatus whose necessary recovery time including a time taken to input data still not backed up satisfies a predetermined requested recovery time, from information processing apparatuses in said second data center;
• and
• a recovery unit for deploying an application used at said first data center in said selected information apparatus and recovering the data at said first data center from said backup at said selected information processing apparatus.
