System has more storage sources.Storage administrator can provide data space using traditional disk array,
Also same mode can be used to go to provide data space using cloud service.Without additional deployment means and knowledge
In the case of, it is no longer limited by local memory capacity limitation.
Detailed description of the invention
Fig. 1 is that NAS Stored Procedure figure is added in the present invention；
Fig. 2 is the work flow diagram of data backup in the present invention；
Fig. 3 is the work flow diagram that data are restored in the present invention.
Specific embodiment
Further explanation is done to the present invention with reference to the accompanying drawing.
The present embodiment is based on mainstream Linux system, such as the redhat/ of debian/ubuntu or the rpm series of deb series
Centos etc..It is mainly comprised the steps that as shown in Figure 1, adding NAS Stored Procedure in the present embodiment
Step 11: the NAS memory space serviced being mapped to local by network protocol nfs or cifs agreement, then will be mapped to
The memory space of local NAS service is device block by fuse (user's space file system) technical transform；Directly as this
Ground equipment uses.Fuse technology is the api interface that a set of linux is provided, and can make logical device.In general, each NAS service
Memory space in server-side be a file directory, a catalogue can be converted into a local infrastructure device.One mesh
Record can also be converted into local multiple infrastructure devices, that is, do more parts of mappings, can do more parts of backups to file-level data in this way.
Either one or multiple infrastructure devices, when towards local living document system be it is similar, we eventually
They switch to a unified storage pool.NAS memory space by conversion mapping is local infrastructure device, all local texts
The experience and knowledge of part system can be reused, and also avoid hard link, extended attribute, POSIX locking etc. etc. can
The mistake that can cause.In the present embodiment, the address nas server ip: 10.0.60.28；Nas server catalogue :/home/
remote；Local directory :/home/local；By the scheduling of fuse API, ultimately generate/home/local/file01
Equipment.The scheduling reality of fuse API is exactly the process with development language tune interface.Linux provides so a set of api interface,
Then api interface is called.
Step 12: whether judgment step 11 succeeds, and thens follow the steps 13 if succeeded, if it fails, if unsuccessfully move back
Out.When living document system creation pond, if the disk failure after mapping failure or conversion, is that can not successfully create into
Storage pool.
Step 13: being instructed using the zpool in living document system, zfs(of the creation comprising NAS service local device is dynamic
State file system) pond；
Step 14: whether judgment step 13 creates success, if it succeeds, end operation, if it fails, then unsuccessfully exiting.
In more specifically usage scenario, it is also necessary to the attribute in the pond zfs be set and configure the clothes of mapping services and zfs
Business, which is thought highly of, opens recovery.Wherein, the attribute in the pond zfs includes capacity limit, enabling compression etc..Mapping services, that is, nas memory space
It is mapped to local function.Configuration mapping services can be unified in the rc.local configuration file of linux, and setting script opens
It is dynamic.
After completing NAS Stored Procedure, start carry out data backup, specific backup method as shown in Fig. 2, include with
Lower step:
Step 21: the zfs(living document system comprising NAS service local device created in step 13) storage is created on pond
Logical volume.
Step 22: data are backed up.Wherein, the backup mode of data it is general there are two types of, one is pass through network assist
ISCSI/IB/FC is discussed, memory space is mapped to client, the read-write operation of data is directly carried out in client；Another kind is
By rsync etc. third party's network backup software, the backup operation of data is carried out between storage and client.
Step 23: after storage location is written in data, i.e., after data backup success, currently stored logical volume being done at snapshot
Reason, storage snapshot can be used for the recovery reduction of data.Since the underlying device of zfs is formed by NAS service reverse proxy, therefore data
NAS server-side can be synchronized to.
Step 24: after completing step 23, cancelling storage mapping.In the process once backed up, correlative link has not only been configured
Border will also carry out necessary recovery processing after data end of transmission, in order to avoid system environments is influenced, so needing to cancel storage
Mapping.
As shown in figure 3, using method provided in this embodiment backup data restore when the following steps are included:
Step 31: clone's processing being complied fastly to time point of specified recovery corresponding storage logical volume, that thus bears new patrols
It collects volume and is cloned into new logical volume without influencing original logical volume, data；
Step 32: being restored data to given client end using rsync etc. network backup software；Or use nfs(network text
Part system) etc. network protocols carry memory space to client；So directly using storing data without being restored.It is this
The mode of quick pull-up business is suitable for database and promptly replaces use etc. business scenario.
Step 33: data then cancel storage mapping and destroy clone volume after being successfully recovered.
The above is only a preferred embodiment of the present invention, it should be pointed out that: for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
