Specific embodiment one
System architecture shown in composition graphs 1 (a), the embodiment of the present invention proposes a kind of method of generating snapshot, as shown in Figure 8, for carrying out snapshot operation to the data of application, such as, the data of APP1 are backed up, described APP1 operates on VM1, VM2 and VM3, wherein VM1 and VM2 is deployed on deployment server A, and VM3 is deployed on deployment server B, and described method can comprise:
S801: backup server receives backup instruction, and described backup instruction carries the mark of APP1.
Described backup instruction carries the mark of application, the mark of such as APP1, after described backup server receives described backup instruction, starts and backs up the data of APP1, the mark of wherein said application can be the title of application or ID, and the embodiment of the present invention is in this no limit.
Described backup instruction can be triggered according to demand by user, such as, when needing to back up the data of APP1, user sends described backup instruction to described backup server, described backup instruction carries mark and the indication information of described APP1, described indication information is used to indicate and carries out conforming snapshot operation to the data of described application, and described backup server can receive the described backup instruction that user triggers, and backs up the data of APP1;
Described backup instruction can also be carry out timing by described backup server according to the backup policy of the application pre-set to generate, such as, the backup policy that user can pre-set APP1 in described backup server was: every 10 hours, the data of APP1 are once backed up, then described backup server was every 10 hours, generate once described backup instruction, described backup instruction carries the mark of APP1, then described backup server according to the described backup instruction of timing generation, can start and back up the data of APP1.
S802: described backup server is sent as to cloud operations server the request that application APP1 creates snapshot.
After receiving described backup instruction, described backup server is sent as to described cloud operations server the request that application APP1 creates snapshot, the mark of described APP1 is carried in the described request for application APP1 establishment snapshot, to indicate the data creation snapshot that described cloud operations server is APP1
The described request for application APP1 establishment snapshot is except carrying the mark of described APP1, also carry indication information, described indication information is used to indicate described cloud operations server and carries out conforming snapshot operation to the data of described APP1, thus realize unifying backup to each the virtual machine running APP1, ensure the consistance of Backup Data.
S803: described cloud operations server, according to the mark of described APP1, determines the multiple stage virtual machine running described APP1.
Described cloud operations server receives the described request for application establishment snapshot, and determines the multiple stage virtual machine running described APP1, so that the follow-up multiple stage virtual machine to running described APP1 carries out snapshot operation.
Described cloud operations server collects the configuration information of described APP1 after can disposing APP1 in system 1, and the configuration information of such as APP1 can comprise:
1) virtual machine running APP1 is: VM1, VM2 and VM3;
2) VM1 and VM2 is deployed on deployment server A;
3) VM3 is deployed on deployment server B;
Then described cloud operations server is according to the configuration information applied in the identified query system of APP1, can determine that the multiple stage virtual machine running described APP1 is: VM1, VM2 and VM3.
