Description
Technical field
The present invention relates to distributed data management fields, and in particular to a kind of to handle the method, apparatus for managing data and divide
Cloth disaster recovery method, system.
Background technology
In a distributed system, generally use carrys out the external services device in management system using central server.In so-called
Central server is responsible for the server of one distributed system of management, also referred to as management server, and external services device is opposite
The common server of role of manager, also referred to as quilt are not served as in for central server, in particular to distributed system
Management server.The distributed system being made of central server and external services device can be used for the disaster tolerance of data center.
In traditional distributed system, central server manages external services device, and usually there are two types of different methods.First
Kind method is that only there are one the central servers for serving as role of manager in entire distributed system, i.e., only with a center service
Device manages all external services devices.Second method is that have multiple serve as in role of manager in entire distributed system
Central server, i.e., multiple central servers can manage all external services devices.In the second approach, in order to avoid more
A central server generates managerial confusion to system, and the same time only allows a central server to carry out pipe to peripheral server
Reason, other central servers are responsible for monitoring its state.When the central server for being responsible for external services device breaks down,
It is replaced using another central server, continues the responsibility for fulfiling management external services device.
The first method defect that the above-mentioned prior art provides is obvious, that is, disaster tolerance can be poor, for example, ought be only
When some central servers break down, entire distributed system may be caused to be not normally functioning.The defect of second method
It is：It is inconsistent due to multiple central server condition monitorings so that system may not act as role of manager actually
Central server, or exist simultaneously the central server of multiple identical roles of manager and lead to managerial confusion.For example, it is assumed that
There are tri- external services devices of two central servers of M1 and M2 and S1, S2 and S3 in system, wherein M1 is Current central service
Device, M2 monitor M1.It is further assumed that M1 and M2 are in the same subnet 1（Hereinafter referred to as N1）In, S1, S2 and S3 are in another
Subnet（Hereinafter referred to as N2）In, under normal circumstances, N1 and N2 are intercommunications.When intermediate routing is gone wrong, N1 and N2 are disconnected,
M1 and M2 still can be communicated, and the state that M2 monitors M1 is normal, however, S1, S2 and S3 can not be communicated with M1, it is this
Actually without the central server for serving as role of manager under scene.For another example, it is assumed that M1 and M2 is in different respectively
Subnet（Hereinafter referred to as N3 and N4）In, S1, S2 and S3 are remained in N2.When N3 and N2 communications are normal, N4 and N2 are communicated also just
Often, when the connecting fault of N3 and N4, M2 is mistakenly considered M1 failures, therefore starts to manage S1, S2 and S3 these three external services
Device, however, M1 is still in these three external services devices of normal management S1, S2 and S3 at this time, so as to cause the same time, there are two
Managerial confusion caused by a central server.
