Definitions
- the invention relates to an arrangement for archiving or dearchiving data from at least one data source, which can be coupled to at least one external archive memory via data transmission means. Furthermore, the invention relates to a system for outsourcing, archiving and / or retrieving data, which is suitable for use in the arrangement mentioned, and at least one archive memory and data transmission means for coupling it to one or more data sources and / or to one or more local ones Networks each with one or more data sources. The invention further relates to an interface for such an archiving system.
- archive solutions are known in which the user's computer systems are connected via local networks to a user-owned, that is to say locally installed, archive system (for example, a separate computer system).
- Off-line media such as floppy disks, CD-Roms, magnetic tapes, etc., which are written on hardware installed by the user and are connected to the user data processing system via customer-specific data interfaces (e.g. SCSI, home network), are also used for archiving used.
- customer-specific data interfaces e.g. SCSI, home network
- the object of the invention is to create a safe and efficient, and above all economically operable archiving system which avoids the disadvantages mentioned above and which is designed for (quasi) simultaneous processing of a large number of archiving tasks, in particular different archiving clients.
- an archiving arrangement of the type mentioned at the outset proposes that at least one long-distance network or wide area network, and thus interfaces connected therefrom, be arranged as data transmission means, via which a plurality of spatially or geographically distant data sources and / or different local networks with one or more data sources can be coupled centrally to the archive store (s), and the archive store has memory areas which can be separated from one another and are each assigned to one or one of the spatially distant data sources or local networks.
- the interfaces for connecting the data sources, local networks and / or the archive memory to the long-distance network so-called bridges or, in the other case, gateways are suitable, given the same structure of the networks to be connected.
- a centralized long-distance archive for a large number of external users can be created, which is based on an arrangement of data processing components (hardware and software) for the archiving and management of data which are generated on user-oriented computer systems.
- the long-distance or wide area network (WAN) is linked to an archive system in a new way.
- This enables the archiving of user-specific data externally on an archive system that is foreign to the user.
- This enables a short, medium or long-term storage (archiving) of data (e.g. text documents, graphics, images, personal data, construction drawings, etc.) that are based on the user-oriented computer systems (typically PC, Workstation) have been created by the user with commercially available or special software.
- this data can be transferred via the wide area network, e.g. B. ISDN, Internet or company-owned networks.
- the archiving process can be carried out by writing the relevant data on off-line media those that are not available to the user, but rather are installed by a remote archive operator.
- the investments required for archiving the data in an archiving system (hardware and software) and the logistical effort in maintaining the archive, including personnel for the administration of off-line data carriers, are much easier to amortize.
- the data transmission means have a plurality of interfaces which are each designed for connection to a long-distance network or wide area network and which connect the one or more data sources and the archive memory serve to the wide area network, and the addressing of the archive store is linked to a user filter which is designed to separate and / or separate data from different data sources in the archive store.
- a user-installed interface e.g. B. gateway
- B. gateway which is a component of the centralized long-distance archive system, the connection of an archive user.
- the connection to the archive component is established via a new archiving bus system with a wide area network, which is implemented as a dedicated line or dial-up connection in a corresponding public long-distance network and an archive-side interface, for example a gateway.
- This connection according to the invention of the user-oriented computer systems to the archive component or the archive memories with an upstream wide-area interface allows data to be transmitted between the user computer and the archive over practically any spatial distances (“long-distance traffic”)
- long-distance traffic
- data can be archived from virtually any number of users who are no longer local to the archive component or the archive memory, as is the case in the prior art, but are now arranged externally (multiple, external use possibility of the archive system according to the invention)
- the archiving is centralized in an external component for the large number of users.
- a media transfer module is carried out, which is coupled to the archive storage or its (possibly outdated storage media) is designed for the data transfer thereof to physically different, preferably more modern storage media.
- an interface for the wide-area archive system mentioned which is characterized by a two-port memory which is to be archived or de-archived at its input or output for intermediate storage and which has one gate either with the Data source or the bus of a local network belonging to the data source, for example, or with the archive store and with its other gate can in each case be connected to the wide area network.
- This interface can form a part of the wide area archive installed on the user side as well as on the archive side.
- the functional component “interface” first receives and (temporarily) saves the data to be archived from the data sources and decouples - on the archive user side compared to the wide area network - the data sources from the archiving process that takes place via the wide area network the interface according to the invention - on the archive side compared to the wide area network - can also be used to decouple the archiving process from communication with the interface on the other archive user side. After complete transfer of the data to be archived through at least two interfaces according to the invention (once archiving can be done via the intermediate wide area network.
- a plurality of local networks 2 are each coupled to a public wide area network (“data highway”) 1 via a user gateway 3.
- data highway public wide area network
- a plurality of user data sources 4 are networked via a respective local bus 5.
- An archive store 7 is also connected to the wide area network 1 via an archive gateway 6. This is used to store the data to be archived along with the corresponding database to be archived using suitable technology, with a separation according to users, that is to say the various ones Data sources 4.
- a media transfer module 8 is linked to the archive storage system 7 and is used to update the media or storage technology used, because the media used for archiving are subject to rapid, technological progress and change. By means of the media transfer module 8, it is possible to archive all arch Transfer ived data to new media of current technology. This ensures the long-term availability of data and database.
- the internal structure of the user-side gateway 3 is illustrated in more detail in FIG. 2:
- the connection to the local bus 5 of the local network 2 (“LAN” - see FIG. 1) takes place via a bus 9 for internal communication of the gateway 3
- User data from the local network are Transfer archiving requests 10 to a monitoring and control unit 11. This can pass on corresponding requirements 12 to the archive gateway 6 (cf. FIG. 3) for triggering the archiving to a further bus 13 for external communication, which is coupled to the public wide area network 1 (cf. FIG. 1).
- the bus 13 can enter feedback 14 from the archive-side gateway 6 for archiving into the monitoring and control unit 11 for external communication.
- This plant controls the entire archiving process on the user side and monitors the status of the storage components required for storing data to be archived, database and the respective backup copies (for example “memory full”).
- a two-port memory 16 connected directly to the bus 9 for internal communication forwards data read in by the bus 9 at its output gate both to a data compression module 17 with integrated data encryption for the purpose of data protection and to a database 18.
- the two-port memory 16 is an essential component of the data transfer from the data sources 4 via standard network protocols (for example TCP / IP, Novell, DICOM) through the user-side gateway 3. Only after the data to be archived has been completely received (stored) The archiving process is started in the two-port memory 16. The effect of decoupling the communication between the user gateway 3 and the archive gateway 6 is thus achieved. The same applies in the dearchiving direction 20 that is opposite to the archiving direction 19.
- the data is compressed in the data compression module 17. Since they leave the user's sphere of influence during archiving, encryption with a user-defined password is necessary for data protection reasons.
- the user-specific database 18 is expanded by all the information required for identification and dearchiving.
- Both the data compression module 17 and the database 18 are each linked to one of two backup copy modules 21, 22.
- the first-mentioned module 21 is used for data security in that the compressed data record is stored on a memory that is physically independent of the two-port memory 16 (redundancy). The data is therefore available at all times during the archiving process. twice in the centralized long-distance archive system.
- the second backup copy module 22 is activated after each change in the content of the database 18 in order to create a complete backup copy thereof.
- the monitoring and control unit 11 also actuates a timer module 23, which controls the start of the data transmission to the centralized long-distance archive in dependence on a preselected time of day and the data volume to be archived, depending on the archiving process. This means that the transmission can take place at the cheapest tariff times of the wide area network provider (e.g. Weg).
- the timer module 23 triggers a module 24 to set up a connection via the wide area network 1 with the archive gateway 6. This enables the transfer of the backup copies from the database 18 and the compressed data, going back to the two-port memory 16, to the archive gateway 6.
- an address memory 25 is actuated by the control unit 11 during the process of the dearchiving 20 when the control unit 11 receives a user dearchiving request 26 from the bus 9 for internal communication.
- the archive user determines which of the data sources 4 from the local networks 2 (cf. FIG. 1) should have the data to be dearchived.
- the data are then automatically transferred to the data sources specified by the address memory 25.
- the dearchived data must be decompressed for use by the user, for which purpose a decompression module 27 is used. This is described on the input side by a further two-port memory 16b serving as an intermediate buffer, the input of which can be coupled directly to the bus 13 for external communication when activated by a connection setup and access module 28.
- connection to the archive gateway 6 for the retrieval 20 is established according to the corresponding request 26 by the user to the control unit 11 which also controls the connection establishment module 28 from the user gateway 3 and is dependent on the input of a correct access code via the retrieval request 26.
- a comparison submodule integrated with the connection setup module 28 can serve this purpose. If, for example for maintenance and diagnostic purposes, the connection from the archive gateway 6 to the user gateway 3 is opened in the opposite direction, access to data in the user gateway 3 may only be made after the transmission of an access code stored in the user gateway 3 from the archive gateway 6 to the user gateway 3 respectively.
- the comparison module 28 is also expediently designed for this.
- the archiving gateway 6 has an internal structure, also shown separately according to archiving 19 and dearchiving 20, as follows:
- the direct connection to the wide area network 1 also takes place via a bus 29 internal to the gateway for external communication.
- the archiving / de-archiving requests 12, 26 or feedback 14 originating from the user and / or from the archive-side control unit 11a and respectively transmitted via the wide area network 1 are forwarded to the archive side or to the user side.
- the archive-side control unit 11a controls a similar two-port memory 16a, which is used for data transfer with the user gateway 3.
- the archiving process does not begin until the data to be archived has been completely received (stored) in the two-port memory 16a, the archive memory 7 being written in accordance with the archiving direction 19. Communication between the two gateways 3, 6 on the user and archive side is thus decoupled from the archiving. The same applies in the opposite direction 20 for dearchiving.
- the output gate of the two-port memory 16a is influenced by a user filter 30, which is used for addressing and keeping different memory areas in the archive memory 7 for users 1, 2,... K-1, k.
- the user filter 30 ensures that each user can transfer only in his area in the archive memory 7 and in the archive database 70.
- the archived data and the content of the archive database 70 are each stored on a second, physically independent memory (not shown) by means of a respective backup copy module 21a, 22a. This means that the archived data and database content are always available in the long-term centralized long-distance archive.
- the monitoring and control unit 11a in the archive gateway 6 controls the entire archiving process on the archive side and monitors the status of the memories required for storing data to be archived, database contents and the respective backup copies (for example “memory full").
