1. A storage system comprising:
a first storage apparatus configured to store data in response to a read/write request from a first host;
a recovery storage apparatus configured to store recovery data for recovering the data; and
a management apparatus configured to cause a second host to perform a business process using the data,
wherein the second host is stopped in advance, and
wherein, when the second host is caused to perform the business process, the management apparatus prepares a second storage apparatus, causes the second storage apparatus to recover and store the data using the recovery data, and starts the second host based on control information for designating the second storage apparatus operating in response to a request from the second host,
wherein, based on the control information, the management apparatus prepares the second storage apparatus by deploying the second storage apparatus so that the second storage apparatus has a storage capacity in which the data is storable,
wherein the management apparatus prepares the second storage apparatus in units of regular volumes supplied for the first host to store the data in the first storage apparatus or in units of groups including one regular volume or a plurality of regular volumes, and
wherein the management apparatus determines whether data related to the regular volume or the group is recovered to the second storage apparatus prepared in advance based on the control information when the second storage apparatus is prepared, the management apparatus increases a capacity of the second storage apparatus based on the control information when data is recovered to the second storage apparatus prepared in advance, and the management apparatus deploys the second storage apparatus newly when data is not recovered to the second storage apparatus prepared in advance.
