DM Server sends the request message that connects to subscriber terminal equipment, after described subscriber terminal equipment is received this message, sends to DM Server and to receive the response, and finishes being connected between DM Server and the subscriber terminal equipment.
S2, device management server send recovery request message to terminal equipment.
After connecting, DM Server initiatively initiates to recover flow process.According to the confirmed renewal mistake of operator, when making up recovery request message, the data content corresponding with described mistake is carried in the described recovery request message, be used to inform which data terminal equipment need recover.Afterwards described recovery request message is sent to subscriber terminal equipment.
S3, from Backup Data, extract restore data.
After terminal equipment is received described recovery request message, determine the needs data recovered according to the content in this message, and search and extract with it corresponding Backup Data, if what adopt is mode to the different backup node of the data creation of different editions, then can select to recover the data of which version by the user.
If what adopt is the method for creating backup node under the node of data to be updated place, then as Fig. 8, shown in Figure 9, the original path of data is the even higher level of node of described backup node; If what adopt is to create the backup tree, perhaps under arbitrary node, create the method for backup node, then as Figure 10, shown in Figure 11, the node path that need restore data place of the original path of data under former root node, finding.
S4, covering current data.
According to the original path of these data that parse, cover current data with the Backup Data that extracts, finish recovery operation.
Whether S5, judgement recover successful, and report recovery situation.
After recovery operation was finished, terminal equipment judged whether recovery is successful.After drawing judged result, terminal equipment sends recovery situation message to DM Server, carries the code that is used for the identification recovery situation in described recovery situation message, and for example: 1 representative recovers successfully, and 2 representatives recover failure, the no corresponding restore data of 3 representatives.After DM Server receives described recovery situation message, therefrom obtain and resolve described code, and then whether decision is necessary to initiate once more to recover flow process.If the code DM Server according to recovery situation confirms that needs do not initiate to recover flow process once more, then send deletion message to terminal equipment, inform described terminal equipment deletion backed up data.Obtain a result show recover successfully after, terminal equipment also can initiatively be deleted backed up data, with conserve storage.Certainly, after recovering successfully, also can not delete backed up data, so that follow-up flow process is used.
Step by the autonomous restore data of user is as follows:
When going wrong after S1, user find to upgrade, can independently initiate to recover flow process.
S2, determine the needs data recovered, and from Backup Data, extract restore data according to the mistake of finding, and the original path of resolving these data.
The data that S3, usefulness are extracted cover current data.
After S4, recovery operation are finished, judge and whether successfully recover, if recover successfully can delete or not delete backed up data.
When recovering the terminal equipment data, also Backup Data can be uploaded to and by the equipment control service terminal equipment be carried out data again behind the device management server and recover, its treatment step is as follows:
S1, device management server and terminal equipment connect.(identical) with example 1 content
S2, DM Server data recovered content as required extract corresponding data and path thereof from described terminal equipment.
S3, this packing data is handed down to described terminal equipment.
