Abstract

Title: Digital document archives useing predefined "document relocation procedure" (relocation policy) over multiple types of storages through networks This invention is about document archive system and procedure using multiple types of storage systems located at multiple places on a network. The invented system consists of a MFP (Multiple Function Peripheral) and various types of mass storage units, which are connected by a network such as Internet. A typical configuration will be a combination of a MFP, an independent hard disk storage unit, and an independent high volume tape storage unit, The system also includes a document archive system program, which manages storage, retrieval, and relocation of archived documents, using "document relocation procedure file" and "document relocation status file".. The MFP has various functional capabilities such as printer, facsimile, and document scanner. The MFP can receive digital document data through the network, can print the document, and can store the digital document data into the disk storage equipped in the MFP. The MFP can also scan any paper document and store the scanned digital data in the disk storage in the MFP.

This invention is about document archive system and procedure using multiple types of storage systems located at multiple places on a network.

The invented system consists of a MFP (Multiple Function Peripheral) and various types of mass storage units, which are connected by a network such as Internet. A typical configuration will be a combination of a MFP, an independent hard disk storage unit, and an independent high volume tape storage unit, The system also includes a document archive system program, which manages storage, retrieval, and relocation of archived documents, using "document relocation procedure file" and "document relocation status file"..

The MFP has various functional capabilities such as printer, facsimile, and document scanner. The MFP can receive digital document data through the network, can print the document, and can store the digital document data into the disk storage equipped in the MFP. The MFP can also scan any paper document and store the scanned digital data in the disk storage in the MFP.

Generally speaking, newly created documents are frequently retrieved and printed from the document archive system. For the purpose, they had better to be located in the MFP's internal disk storage, because they are quicker to retrieve. However, the MFP's internal disk has limited capacity and it will easily become full when new documents are stored into the MFP. Consequently, it is natural to think about extending the storage to auxiliary independent hard disks and tape storage through networks. Auxiliary hard disks cost less than the MFP internal disks to store a document, instead, time to retrieve and print the document becomes longer because it will take time to retrieve the file from the auxiliary disk, transfer it to the MFP and print. Auxiliary tape storage is cheaper than the auxiliary disk storage, however, it takes longer time to retrieve a file from the tape storage because a tape storage doesn't allow random access. Thus, it is a kind of trade-offs between time required to retrieve and storage cost per document. Fig.1 shows the basic idea of document relocation from MFP to auxiliary storages.

Fig. 1 Automatic relocation of document data

This invention is about the system and method, in which a digital document archive system will automatically move document data from a MFP to other independent hard disk storage and tape storage using "document relocation procedure" record for each document. A document relocation procedure record is generated for each document when a document is stored by the MFP, and added to a "document relocation procedure file", which is maintained by the document archive system. When a MFP local dis...
