Abstract

An arrangement for filing and retrieving data of a plurality of mutually remote data sources which are connected to a remote central file-storage system by a public, wide-area transmission network. Mutually separable storage fields are maintained in the central file-storage system by allocating separate storage fields to the data of each of the remote data sources by a user filter coupled to the file storage system to ensure that every user can transfer in the central file system only in his field. An access authorization code transmitted from a remote data source is compared to an access code stored in the file-storage system to permit access by a remote data source to the separate storage fields allocated to the data source seeking access.

Claims

1. A method for archiving and de-archiving data of a plurality of geographically mutually remote data sources, the method comprising;

(a) coupling the data sources through a public, wide-area data transmission network to a central file-storage system external and geographically remote from the data sources;

(b) buffering data transmitted over the network in interfaces connected between the network and each remote data source;

(c) maintaining mutually separable storage fields in the central file-storage system by allocating separate storage fields to the data of every one of the remote data sources by a user filter coupled to the file-storage system to ensure that every user can transfer in the central file storage system only in his field; and

(d) comparing an access authorization code transmitted from a remote data source to an access code stored at the central file-storage system and permitting access by a remote data source to the separate storage fields allocated to the data source in the central, file-storage system after comparison of the access authorization codes.

2. An apparatus for archiving and de-archiving data of a plurality of geographically mutually remote data sources, the apparatus comprising:

(a) a central, file-storage system external and geographically remote from the data sources;

(b) a public, wide-area data transmission network coupling the central, file storage system to the data sources;

(b) interfaces interposed between the network and each remote data source for buffering data transmitted over the network and coupling remote data sources to the file storage system after comparison of access authorization codes; and

(c) a user filter coupled to the storage system and allocating mutually separable storage fields in the central file-storage system, separate fields being allocated to the data of every one of the remote data sources to ensure that each remote data source can transfer with the central file storage system only in the field allocated to it.

3. An apparatus according to claim 2 wherein the interfaces are bridges or gateways for linking the data sources and the file-storage system to the wide-area network.

4. An apparatus according to claim 2 or 3, wherein a media transfer module is coupled to the file-storage system for data transfer between physically different storage media.

5. An apparatus according claim 2 and further including a field for storing data for identifying and retrieving the data associated with a data source is provided in the file-storage system.

6. An apparatus in accordance with claim 2 wherein the interfaces include a two-port store for temporarily storing data, the two-port store capable of being coupled by one port to the data source and by its second port to the wide-area network, the two port store being linked with a connection setup module for setting up a connection of the two-port store via the wide-area network to a file storage interface at the file-storage system in order to enable or disable said connection setup module, the connection setup module linked with a comparison submodule for comparing the access authorization codes.

7. An apparatus according to claim 6 wherein the file storage interface includes a two-port store having a first port, which can be connected to the file-storage system, for routing by the user filter to predetermined address fields.

8. An apparatus according to claim 6, at least one of the interfaces includes a data-compression module and a data-decompression module linked to the two-port store.

9. An apparatus according to claim 6 and further comprising a database module coupled to the two-port store, for storing data for the identification and retrieval of data-source-specific data.

10. An apparatus in accordance with claim 6 and further comprising a backup copy module linked to the two-port store.

11. An apparatus in accordance with claim 6 and further comprising a time-control module for the predetermined triggering of a module for setting up a connection of the two-port store via the wide-area network with the file-storage system.

12. An apparatus in accordance with claim 6 and further comprising an address store for an adjacent local network for specifying the target addresses on a bus of the local network for data to be retrieved from the two-port store connected to the local network bus.
