ABSTRACT:
To provide a backup method that allows a reliable backup when a fault occurs in a way that improves a backup speed. The backup method for requesting a backup system to back up files (31) stored on a predetermined NAS of plural NASs (1and2) in response to a backup request given from a client computer, includes: selecting backup target files based on the backup request given from the client computer; allocating the selected backup target files (31) respectively to the plural NASs (1and2); and causing the respective NASs to request the backup system to back up the allocated files (31) in parallel (102and202).
