Abstract
The invention discloses a data backup method and device. The data backup method comprises the following steps: visualizing one part of hard disk in a server into a virtual tape library, wherein the left hard disks are real physical hard disks; classifying data which needs to be backuped, wherein the data comprises the data which needs to be backuped for a long time and the data which needs to be backuped for a short time; backuping the data which needs to be backuped to the virtual tape library; and transferring the data which needs to be backuped for a long time into the real physical hard disks from the virtual tape library to be stored. The technical scheme firstly backups the data which needs to be backuped to the virtual tape library, so that the technical scheme is high in speed and efficiency, the data which needs to be backuped is classified, the data which needs to be backuped for a long time is transferred to the real physical hard disks, and transferring work can be carried out when the server is idle. Compared with the prior art, the data backup method and device is more scientific and can hierarchically store the data in a targeted way.

Summary of the invention
In order to solve the problem, the invention provides a kind of data back up method, described method comprises:
By virtual for a part of hard disk in server be VTL, remaining hard disk is real physical hard disk;
The described data of backup that need are classified, comprises and need the data of long term backup and the data of short-term backup;
Described VTL is backuped to by needing the data of backup;
Need the data of long term backup to move to described real physical hard disk from described VTL to store by described.
Alternatively, before the data of needs backup are backuped to described VTL, described method comprises: utilize and repeat deleting technique, processes, the data after process are backuped to described VTL to the described data backed up that need.
A kind of data backup device, described device comprises:
Virtual module, for by virtual for a part of hard disk in server be VTL, remaining hard disk is real physical hard disk;
Sort module, for classifying to the described data of backup that need, comprising and needing the data of long term backup and the data of short-term backup;
Backup profiling module, for will the data of backup be needed to backup to described VTL,
Real physical hard disk is moved to from described VTL by needing the data of long term backup.
Alternatively, described device also comprises: data de-duplication module, before the data of needs backup are backuped to described VTL, utilizes data de-duplication technology, the described data of backup that need are processed, the data after process are backuped to described VTL.
Technical scheme of the present invention, first will the data of backup be needed to backup on VTL, speed is fast, and efficiency is high, and to needing the data of backup to classify, to the Data Migration of long term backup be needed on real physical hard disk, migration work can utilize the time of server free to carry out, compared with prior art, and science more, have levels ground more, carries out data storage targetedly.
Accompanying drawing explanation

Fig. 2 is a kind of data backup device of the present invention.
Embodiment
Below in conjunction with drawings and Examples, technical scheme of the present invention is described in detail.
It should be noted that, if do not conflicted, each feature in the embodiment of the present invention and embodiment can be combined with each other, all within protection scope of the present invention.In addition, although show logical order in flow charts, in some cases, can be different from the step shown or described by order execution herein.
Fig. 1 is the process flow diagram of the method for a kind of data backup of the present invention;
Step S01: by virtual for a part of hard disk in server be VTL, remaining hard disk is real physical hard disk;
Step S02: the described data of backup that need are classified, comprises and need the data of long term backup and the data of short-term backup;
Step S03: backup to described VTL by needing the data of backup;
Step S04: need the data of long term backup to move to described real physical hard disk from described VTL to store by described.
Back-up storage all-in-one is installed virtual tape library software (VTL), by the local disk that various dissimilar disk space (HDD) can be backup server, also can be that the File System Virtual of the various ways such as CIFS, NFS network disk is VTL.VTL to have compared with true tape library read or write speed and consistent operational means faster, not only substantially reduces backup window (namely backing up the required time), improves the resume speed of backup simultaneously.
In the applied environment with big data quantity, VTL can be adopted as recent backup data store space, the data in nearest month or several week are stored in VTL, to be ready for use on fast quick-recovery during application and trouble; Long-term data then regularly move into real tape base system to reduce carrying cost according to user-defined strategy, and provide the reservation of long data and system disaster tolerance far.
Certainly, the division of long-term and short-term, can as required, arrange voluntarily, such as arranging fortnight is short-term, and it is long-term for exceeding fortnight, etc., the application does not limit.
Alternatively, before the data of needs backup are backuped to described VTL, described method comprises: utilize and repeat deleting technique, processes, the data after process are backuped to described VTL to the described data backed up that need.
Repeat deleting technique, data de-duplication technology is a kind of data reducti techniques, normal and standby system conbined usage, the redundant data in deletion system.Fig. 2 is a kind of data backup device of the present invention.
A kind of data backup device, described device comprises:
Virtual module 201, for by virtual for a part of hard disk in server be VTL, remaining hard disk is real physical hard disk;
Sort module 202, for classifying to the described data of backup that need, being divided into and needing the data of long term backup and the data of short-term backup;
Backup profiling module 203, for will the data of backup be needed to backup to described VTL,
Real physical hard disk is moved to from described VTL by needing the data of long term backup.
Alternatively, described device also comprises: data de-duplication module, before the data of needs backup are backuped to described VTL, utilizes data de-duplication technology, the described data of backup that need are processed, the data after process are backuped to described VTL.
Invention main points:
1. namely a machine possesses backup functionality, possesses memory function again, is that the backup storage system of a set of integration is referred to as all-in-one.
