Abstract
The invention provides a data migration method based on a network file system NFS and belongs to the technical field of data migration. By the adoption of the network file system NFS, available space in a new server system is shared with an origin server system so that data can be directly put into the storage space shared by the new server system when data exporting is conducted, and when the new server system data importing is conducted, the locally stored data can be directly imported into a database. The data migration cost is reduced, and the efficiency and the security of data migration are improved.
Description
Technical field
The present invention relates to Data Transference Technology, more particularly to a kind of data migration method based on NFS NFSs.
Background technology
When carrying out Data Migration, we can have found to be related to following multiple system in transition process：Source server system, new clothes
Business device system, storage system, network system etc..During Data Migration, it would be desirable to first data are derived from source server system,
Deposited by storage system or other movable storage devices, treat to import data to after the completion of new demand servicing device system debug to
In new demand servicing device system.In whole data migration process, many major generals influence transport efficiency of operating procedure, the hardware for being used sets
Standby quantity will influence the cost and safety of migration.
During Data Migration, it would be desirable to first data are derived from source server system, by storage system or other
Movable storage device is deposited, and treats to be imported data into new demand servicing device system after the completion of new demand servicing device system debug；Data
Need to carry out temporary transient storage to data by storage device in transition process, increased hardware cost.
The content of the invention
In order to solve the problem, the present invention proposes a kind of data migration method based on NFS NFSs.Mainly
Cause the problem that data can not migrate smoothly for the memory space inadequate in data migration process, memory space is carried out quickly
Dilatation, to meet the memory space requirements in data migration process, so as to reduce Data Migration cost, improves the effect of Data Migration
Rate and security.
The technical scheme is that：
A kind of data migration method based on NFS NFSs,
Free space in new demand servicing device system is shared to by source server system by using NFS NFSs, so that
Data can be placed directly in the memory space that new demand servicing device system is shared out when data are derived, new demand servicing device system
System data directly there will be local data and are introduced directly into database when importing.
New demand servicing device Installed System Memory storage space is carried out into configuration sharing by NFS NFSs, then source server
System identification is simultaneously stored shared in carry to local system, and shared storage can be written and read in source server system now
Operation.
When source server system carries out data derivation, data are directly stored in shared storage, now source server system
There is access limit to data with new demand servicing device system；When new demand servicing device system carries out data importing, just can be by shared storage
Data be introduced directly into database, so far Data Migration complete.
The features of the present invention
New demand servicing device system and source server system are set up the shared mechanism of memory space using NFS NFSs.
Because source server system and new demand servicing device system have access limit to shared memory space, so source server
When system carries out data derivation, directly import data to shared memory space.
When new demand servicing device system carries out data importing, directly imported data into database from shared memory space.
The beneficial effects of the invention are as follows
Intermediate storage temporal data is avoided in data migration process, use and the migration operation of hardware device is reduced
Step, reduces cost, improves efficiency and security.
Brief description of the drawings
Fig. 1 is design principle figure of the invention.
In figure, 1 source server system, 2 new demand servicing device systems, 3 NFS NFSs.
Specific embodiment
More detailed elaboration is carried out to present disclosure below according to accompanying drawing：
As shown in figure 1, the main of notebook data moving method includes source server system 1, new demand servicing device system 2, NFS networks text
Part system 3.
When methods described is operated, the memory space of new demand servicing device system 2 is shared by NFS NFSs 3
Configure, then source server system 1 is recognized and stored shared in carry to local system, now in source server system 1
Can shared storage be written and read to wait and operated；When source server system 1 carries out data derivation, data are directly stored in shared storage
In, now source server system 1 and new demand servicing device system 2 have access limit to data；New demand servicing device system 2 carries out data and leads
It is fashionable, just the data in shared storage can be introduced directly into database, so far Data Migration is completed.
Claims (3)
1. a kind of data migration method based on NFS NFSs, it is characterised in that
Free space in new demand servicing device system is shared to by source server system by using NFS NFSs, so that
Data can be placed directly in the memory space that new demand servicing device system is shared out when data are derived, new demand servicing device system
System data directly there will be local data and are introduced directly into database when importing.
2. method according to claim 1, it is characterised in that
New demand servicing device Installed System Memory storage space is carried out into configuration sharing by NFS NFSs, then source server system
Recognize and by shared storage carry to local system, now can be written and read behaviour to shared storage in source server system
Make.
3. method according to claim 2, it is characterised in that
When source server system carries out data and derives, data are directly stored in shared storage, now source server system and new
Server system has access limit to data；When new demand servicing device system carries out data importing, just can be by the number in shared storage
According to being introduced directly into database, so far Data Migration is completed.
