S1: periodically obtain the deployment data of virtual machine storage volume, and according to described deployment number
The incremental deploying data corresponding according to determining described virtual machine storage volume current period.
Specifically, can determine that described virtual machine storage volume current period is corresponding according to following manner
Incremental deploying data: obtain the deployment data that the current period of described virtual machine storage volume is corresponding
And the deployment data that upper cycle is corresponding, and with deployment data corresponding to current period with upper one week
Deployment data corresponding to phase compare, it is thus achieved that the incremental deploying data that current period is corresponding.
It should be noted that the deployment data of the virtual machine storage volume of acquisition in this step are
The full dose of virtual machine storage volume disposes data；Periodically refer to every preset time period, such as, 1
My god, 2 days or 1 week etc., can be configured according to actual needs, the present embodiment is to this most in addition
Limit.
S2: incremental deploying data corresponding for described current period are stored to default strange land storage
Address.
Wherein, described default storage address, strange land stores have at the beginning of described virtual machine storage volume
Beginning data and the incremental data at least one cycle.Wherein, the incremental data in each cycle is
The incremental deploying data that each cycle obtains.For example, described default storage address, strange land
Middle storage has: primary data, period 1 incremental data, incremental data second round ...,
N periodic increment data, wherein N is less than or equal to 1.
It will be appreciated that after storing data in default storage address, strange land for the first time, this strange land
Storage only includes primary data in address.The object of incremental backup is by the most standby for the first time afterwards
The rear produced data increased and revise；The object of incremental backup is by for the first time for the second time
The produced data increased and revise after incremental backup, and so on.
For example, the cycle of setting is 1 day, then enter the data of virtual machine storage volume every day
Row incremental backup, repeat the above steps S1 to S2, can include in the storage of storage address, strange land: base
Volume, day1 increment, day2 increment ..., multiple files of dayN increment, wherein, base
Volume is primary data.Further, the data of the M days are if desired returned to, then by front
Incremental data and the primary data of M days are added, it may be assumed that base volume+day1 increment+day2
Increment+...+dayM increment, so obtain the data of the M days.
As can be seen here, the present embodiment is by periodically obtaining virtual machine storage volume current period pair
The incremental deploying data answered, and incremental deploying data corresponding for described current period are stored in advance
If storage address, strange land in, so, use incremental backup mode Backup Data, each
Backup be only backed up with front once compared with increase and the data that are modified of person.The then number of backup every time
According to not having the Backup Data that repeats, the data volume therefore backed up is little, the time needed for backup
The shortest, and it is greatly saved bandwidth resources.

Change, thus obtain the deployment data that current point in time is corresponding.
Further, by incremental deploying number corresponding for described current period described in above-mentioned steps S2
According to storing to default storage address, strange land, specifically can comprise the steps:
Recover described virtual machine, and incremental deploying data corresponding for described current period are stored to
The storage address, strange land preset.
As can be seen here, after obtaining the incremental deploying data that described virtual machine is corresponding, can recover described
Virtual machine so that virtual machine proceeds work, and incremental data corresponding for current period is sent out
Deliver to storage address, strange land, the most remotely store address.
For example, described default storage address, strange land comprises the steps that long-range network file system
System (Network File System is called for short NFS) catalogue.
Further, in the disaster-tolerant backup processing method that another embodiment of the present invention provides, remove
Above-mentioned steps, the method also comprises the steps:
Generate log recording.Wherein, described log recording includes the mark of described virtual machine, institute
State the data syn-chronization deadline of virtual machine, the data syn-chronization duration, data syn-chronization state,
The size of synchrodata and synchronizing cycle.
So, can be carried out data syn-chronization (i.e. data backup) each cycle by log recording
Carry out detailed understanding.And, when Network Abnormal, the log recording of generation, can be shown that
Data syn-chronization abnormal state, checks for user.
In order to be illustrated more clearly that technical scheme, below by a concrete enforcement
Example illustrates a kind of disaster-tolerant backup processing method, a kind of disaster-tolerant backup system as shown in Figure 2

| VM1 | Success | 2013/1/26 6:05 | 00:00:10 | 41.16MB | 24:00 |
| VM2 | Success | 2013/1/26 14:30 | 00:00:24 | 81.06MB | 24:00 |
As shown in Table 1, it is the 6:05 of 2013/1/26 that virtual machine VM1 synchronously completed the time last time,
The upper subsynchronous duration is 10s, and synchrodata size is 41.16MB, and virtual machine VM1
Synchronizing cycle be 24 hours, and upper subsynchronous success；Virtual machine VM2 synchronously completed last time
Time is the 14:30 of 2013/1/26, and the upper subsynchronous duration is 24s, and synchrodata size is
81.06MB, and the synchronizing cycle of virtual machine VM2 is 24 hours, and upper subsynchronous success.
It should be noted that during Network Abnormal between master computer and backup computer, record different
