Abstract
A storage service system includes a storage service user (SSU) which uses a data accumulation service, and a storage service provider (SSP) which provides a user terminal with a data accumulation area. The SSU monitors a free capacity of its own data accumulation unit such that the free capacity cannot be smaller than a predetermined value, and automatically transfers stored data to the SSP through a network when the free capacity becomes close to the predetermined value. Thus, the SSU can reserve a constant free capacity.
Claims17
A storage service method, comprising:
- monitoring a storage capacity of a data accumulation unit of a user terminal device;
- and
- transferring data of the data accumulation unit to a storage service providing device through a network such that the free capacity cannot be smaller than a predetermined value.
A storage service method, comprising:
- determining whether or not data is deleted or updated in a user terminal device;
- in case data is deleted or updated, transferring the data before deletion or update from the user terminal device to a storage service providing device;
- and
- storing the transferred data in the storage service providing device.
A storage service user terminal device, comprising:
- a data accumulation unit accumulating data;
- a free capacity monitor unit monitoring a free capacity of said data accumulation unit;
- and
- a data transfer unit transferring the data of said data accumulation unit to a storage service providing unit through a network such that the free capacity of said data accumulation unit cannot be smaller than a predetermined value based on a monitor result of said free capacity monitor unit.
A storage service providing device, comprising:
- a reception unit receiving data to be uploaded from a user terminal device through a network to reserve a free capacity such that a free capacity of a data accumulation unit of the user terminal device cannot be smaller than a predetermined value;
- a data accumulation unit storing data;
- a data read unit reading data when the user terminal device requests the data to be downloaded;
- and
- a transmission unit downloading the data read from said data accumulation unit into the user terminal device.
A computer-readable storage medium storing a storage service program used to direct a computer to perform the process comprising:
- monitoring a free capacity of a data accumulation unit of a user terminal device;
- and
- transferring data in said data accumulation unit to a storage service providing device through a network such that the free capacity cannot be smaller than a predetermined value.
