Embodiment may include herein below：
S101：According to the parked snapshot version information of acquisition, judge whether parked snapshot version is recent snapshot version
This upper snapshot version.
Parked snapshot version information may include the time of parked snapshot version and the version number of parked snapshot version,
Certainly, other information during snapshot is may also comprise, this does not influence the realization of the application.
According to the time of the recovery time of the parked snapshot version of acquisition and recent snapshot version, parked snapshot is judged
Version whether be recent snapshot version a upper snapshot version.
According to the version ID for restoring version ID and recent snapshot version of the parked snapshot version of acquisition, sentence
Disconnected parked snapshot version whether be recent snapshot version a upper snapshot version.
A preceding snapshot version for upper snapshot version volume as recent snapshot version, the time of parked snapshot version
The time (i.e. recovery time) of snapshot is carried out for the snapshot version, for example, reel v is respectively in t0、t1、t2、t3、t4Carry out 4 times
Snapshot, when carrying out the 5th snapshot, its a upper snapshot version is t4Snapshot corresponding to moment, i.e. t0For t1Upper one fast
According to version, t2For t3A upper snapshot version, t3For t4A upper snapshot version.
Each snapshot version has a unique identification number, typically can identification number generation it is suitable according to the priority of snapshot
Sequence is named, therefore can be contrasted by snapshot recovery time and current version time, it is determined that whether a upper version, certainly
It can be judged by the comparison of version number, such as the version number of recent snapshot version is v1.2.2, and parked snapshot version
Version number can be v1.2.1, then can determine that the previous snapshot version that parked snapshot version is recent snapshot version, be
Secondary new snapshot.
S102：When judge parked snapshot version for recent snapshot version a upper snapshot version when, according to restore when
Between the target snapshot volume at corresponding moment and corresponding mapping relations are obtained in system is locally stored.
S103：According to target snapshot volume and mapping relations, restored data is obtained from being locally stored in system, to realize snapshot
The recovery of version.

Snapped volume, the first mapping and the second mapping, for recording SNAPSHOT INFO when local storage system is stored beyond the clouds, first
The read-write of snapped volume, the second snapped volume alternately data, first is mapped as the mapping relations of the first snapped volume and reel, and second
It is mapped as the mapping relations of the second snapped volume and reel.
Corresponding mapping relations are target snapshot volume and the mapping relations of reel, for example, when target snapshot volume is fast for first
According to volume, corresponding mapping relations are the first mapping.
When detecting that reel cloud enables, that is, the reel being locally stored in system be converted into cloud volume when, in advance this
Ground storage system creates the first snapped volume, the second snapped volume, the first mapping, the second mapping, first be mapped as the first snapped volume with
The mapping relations of reel, second is mapped as the mapping relations of the second snapped volume and reel, and mapping can be indicated using bitmap.Example
As shown in Fig. 2 the reel V that system is locally stored has four block number evidences, when v changes into cloud volume, the system of being locally stored automatically generates two
It is individual new to correspond to the mapping of the two snapped volumes from simplification volume, i.e. the first snapped volume FCA, the second snapped volume FCB, and reel
fcmapA、fcmapB。
When reel carries out cloud storage, it is necessary to by snapshot operation, when reel carries out first time snapshot, copied for full dose,
Second to it is later be to carry out increment copy every time, when carrying out snapshot, the first snapped volume and the second snapped volume, first are reflected
Penetrate and the second mapping alternation, for example, t0When, initialization volume FCA, fcmapA 0000, fcmapB 1111, high in the clouds
t0Time data copies for the full dose of reel, reads real data from volume FCA, reads to depend in fcmapB 1 position from which block
Put.t0To t1Between, when having main frame IO, COW is performed, COW blocks are changed into 1 by fcmapA, volume FCA record COW legacy datas.t1When, initially
Change volume FCB, fcmapB 0000, fcmapA is constant.High in the clouds t1 time datas are t0To t1Incremental data, data from volume FCB
Read, read which position as in fcmapA 1 position.t2When, alternately return, initialization volume FCA, fcmapA 0000, fcmapB
It is constant.High in the clouds t2Time data is t1To t2Incremental data, data read from volume FCA, read which position as in fcmapB 1 position
Put.The like.
Two snapped volumes that the system of being locally stored includes, the snapshot version at respectively newest moment and secondary new moment it is fast
According to version, therefore, time snapshot version at new moment is being restored, directly can read from snapped volume corresponding to secondary redaction and corresponding relation
Take restored data.
For example, the data of recent snapshot version are read from volume FCA, then the corresponding target snapshot volume of secondary redaction is
Roll up FCB, then can obtains restored data according to volume FCB and fcmapB.
In technical scheme provided in an embodiment of the present invention, two mappings and two snapped volumes replace work when being backed up based on cloud
Under the characteristic of work, two parts of snapped volumes are preserved due to system is locally stored, the respectively newest and time new moment, when the snapshot of parked
When version is time redaction, that is, a upper version for recent snapshot version, can from system direct copying data are locally stored,
Restored, avoid from high in the clouds and obtain data, greatly reduce the time of data acquisition, so as to improve the speed of cloud recovery
Rate, it can also reduce the cost of cloud download.
In order that those skilled in the art become more apparent upon the technical scheme of the application offer, the application is illustrated with instantiation

t0Moment creates snapshot g1, initialize fcmapA and FCA；t1Moment creates snapshot g2, initialize fcmapB and FCB；
t1To t2Between, main frame io has write-in (data block that black is filled in figure) for first piece to reel v, and fcmapB is changed into 1000, FCB
First block deposit COW legacy data.t2Moment, reel v data are black and white (color of data block) in vain, create third time cloud
Snapshot, alternately triggering initialization fcmapA is that 0000, FCA data are empty.Start increment below and copy data to high in the clouds, due to
FcmapB is 1000, therefore the first block number is according to needing to copy high in the clouds g to3First piece of position.Because fcmapA is 0000, therefore
Data are read from reel v, that is, just t1To t2Between, the first block number evidence of main frame write-in, i.e. incremental data.Copy cloud to
Behind end, g33121 are set to, shows that the first block number evidence is stored in g3On, second, four block numbers evidence is stored in g1On, the 3rd block number evidence is deposited
It is placed on g2On.
Latest snapshot data (i.e. g3) point to FCA, secondary new snapshot data (i.e. g2) point to FCB.If reset into g2, then from this
Read FCB, fcmapB in ground.Because fcmapB is 1000, then the first block number copies reel v to according to from FCB readings, other blocks
On reel v, without restoring.Reel v data are black and white in vain after recovery, meet and create g2When t1Time data.
A kind of two fcmap and two snapped volume alternation characteristics in the backup of the application combination cloud, it is proposed that quick cloud
Restored method, two parts of snapped volumes are preserved due to local, be the newest and secondary new moment respectively, if rejuvenation target snapshot is time
