Abstract
Abstract The invention relates to a database system comprising a plurality of stations ( 10 1 , 10 2 , . . . , 10 n ) communicating with one another. The data that is inserted or updated in an originating station is backed up in at least one other station referred to as a “receiving” station. Means are provided so that data of a determined kind can be backed up synchronously or asynchronously on another station depending on whether or not a pre-established criterion is satisfied. For example, data that is modified progressively is backed up asynchronously until the data has finished being modified, and is backed up synchronously once modification has been finished. Such data may be routing data in a telecommunications system.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
122 words
A database system comprising a plurality of stations ( 10 1 , 10 2 , . . . , 10 n ) communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system selectively backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an asynchronous mode, depending on a precedence given to backup security, updating speed and minimization of disturbances on transmission of backup data, with said backup system backing up said data sometimes in said synchronous mode and sometimes in said asynchronous mode.
Claim 2
Dependent Claim
122 words
A database system comprising a plurality of stations ( 10 1 , 10 2 , . . . , 10 n ) communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system selectively backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an asynchronous mode, depending on a precedence given to backup security, updating speed and minimization of disturbances on transmission of backup data, with said backup system backing up said data sometimes in said synchronous mode and sometimes in said asynchronous mode.
Claim 3
Dependent Claim
28 words
A system according to claim 1 , characterized in that backup is performed in non-volatile memory, such as a hard disk, and takes place at the originating station.
Claim 4
Dependent Claim
25 words
A system according to claim 2 , characterized in that backup in said non-volatile memory at the originating station is performed in an asynchronous manner.
Claim 5
Dependent Claim
32 words
A system according to claim 2 , characterized in that backup is performed in read/write memory of another receiving station prior to performing said backup in non-volatile memory at the originating station.
Claim 6
Dependent Claim
45 words
A system according to claim 4 , characterized in that data that is being backed up in the read/write memory of the receiving station is marked, with the mark data being removed after backup has been achieved in the non-volatile memory of the originating station.
Claim 7
Dependent Claim
126 words
A database system comprising a plurality of stations ( 10 1 , 10 2 , . . . , 10 n ) communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an asynchronous mode, depending on whether or not a pre-established criterion is satisfied, characterized in that data that is modified in progressive manner is backed up asynchronously until modification of said data has been terminated, and is further backed up synchronously at the end of modification.
Claim 8
Dependent Claim
126 words
A database system comprising a plurality of stations ( 10 1 , 10 2 , . . . , 10 n ) communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an asynchronous mode, depending on whether or not a pre-established criterion is satisfied, characterized in that data that is modified in progressive manner is backed up asynchronously until modification of said data has been terminated, and is further backed up synchronously at the end of modification.
Claim 9
Dependent Claim
17 words
A system according to claim 6 , characterized in that the progressively modifiable data is routing data.
Claim 10
Dependent Claim
97 words
A database system comprising a plurality of stations communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an the asynchronous mode, depending on a precedence given to backup security, updating speed and minimization of disturbances on transmission of backup data, characterized in that the data is telecommunications data.
Claim 11
Dependent Claim
97 words
A database system comprising a plurality of stations communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an the asynchronous mode, depending on a precedence given to backup security, updating speed and minimization of disturbances on transmission of backup data, characterized in that the data is telecommunications data.
Claim 12
Dependent Claim
142 words
A database system comprising a plurality of stations communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an asynchronous mode, depending on a precedence given to backup security, updating speed and minimization of disturbances on transmission of backup data, characterized in that data of a determined kind is backed up in the asynchronous mode when it is desired to minimize the time required for putting the data into memory at the originating station, and in that the data is backed up in the synchronous mode when it is desired to maximize backup security.
Claim 13
Dependent Claim
142 words
A database system comprising a plurality of stations communicating with one another, said database system including a backup system whereby data inserted and data updated in an originating station is backed up in at least one other station referred to as a “receiving” station, said backup system backing up data of a determined kind in one of two modes, said modes comprising a synchronous mode and an asynchronous mode, depending on a precedence given to backup security, updating speed and minimization of disturbances on transmission of backup data, characterized in that data of a determined kind is backed up in the asynchronous mode when it is desired to minimize the time required for putting the data into memory at the originating station, and in that the data is backed up in the synchronous mode when it is desired to maximize backup security.
