System, data management method, and file server

A data management method to be executed in a system,

• the system including:
• a file server coupled to a plurality of client terminals;
• and
• an archive server coupled to the file server via a network,
• the file server including:
• a first processor;
• a first memory coupled to the first processor;
• a first storage device coupled to the first processor;
• and
• a first network interface coupled to the first processor,
• the archive server including:
• a second processor;
• a second memory coupled to the second processor;
• a second storage device coupled to the second processor;
• and
• a second network interface coupled to the second processor,
• the data management method including:
• a first step of providing, by the first processor, an area for storing data recognizable by each of the plurality of client terminals;
• a second step of determining, by the first processor, whether to store first data into the first storage device based on an attribute of a first storage area in a case where an addition request for storing the first data into the first storage area is received from a client terminal;
• a third step of transmitting, by the first processor, the addition request to the archive server;
• and
• a fourth step of storing, by the second processor, the first data into the second storage device in a case where the addition request is received.

A file server, which is configured to receive an access request transmitted from a plurality of client terminals, and is coupled to an archive server storing data to be accessed via a network,

• the file server comprising:
• a processor;
• a memory coupled to the processor;
• a storage device coupled to the processor;
• and
• a network interface coupled to the processor,
• the processor being configured to:
• provide an area for storing data recognizable by each of the plurality of client terminals;
• determine whether a first storage area is shared by the plurality of client terminals in a case where an addition request for storing first data into the first storage area is received from a client terminal;
• store the first data into the first storage device in a case where the first storage area is determined to be shared by the plurality of client terminals;
• transmit the addition request to the archive server;
• and
• transmit the first data stored in the storage device to a plurality of client terminals other than the client terminal that has transmitted the addition request.
