1. An information processor coupled to a storage apparatus that stores information, comprising:
a processer configured to execute a program; and a memory configured to store the program, wherein the processor performs, based on the program, operations to: read schedule information; check whether a snapshot flag in the schedule information is set; compare, when the snapshot flag is set, a current time with a start time corresponding to the snapshot flag in the schedule information; create, when it is determined that the start time corresponding to the snapshot flag has arrived based on a first comparison result, a snapshot of a file system without stopping an input and an output to and from the storage apparatus and output the snapshot to the storage apparatus; check, after creating the snapshot, whether a copy flag in the schedule information is set; compare, when the copy flag is set, a current time with a start time corresponding to the copy flag in the schedule information; write, when it is determined that the start time corresponding to the copy flag has arrived based on a second comparison result, second information stored in cache memory onto first information that is stored in the storage apparatus and is managed by the file system after the snapshot has been created; and instruct, after writing the second information, the storage apparatus to create a replication of the snapshot and the first information onto which the second information is written. |
