The invention relates to a database system comprising a plurality of stations (101, 102, . . . , 10n) 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.
A database system comprising a plurality of stations (101, 102, . . . , 10n) 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.

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.
