Data backup and configuration method, equipment, storage medium and system

The invention provides a data backup and configuration method and equipment, a storage medium and a system. The method comprises the following steps: firstly, identifying a number analysis table filein a service database of MSAN equipment; reading the number analysis table file; storing the data in another storage space; deleting the number analysis table file in the service database. Therefore,the size of the business database can be greatly reduced; the flow required by the network management system to carry out data backup on all the MSAN equipment managed by the network management systemis greatly reduced; in addition, the MSAN equipment can be successfully configured according to the service database of which the size is greatly reduced when data configuration needs to be carried out, and the problem that in the prior art, when a network management system carries out data backup on all the MSAN equipment managed by the network management system, the needed flow is too large issolved.
