Description
Technical field
The present invention relates to field of storage more particularly to a kind of method and system for realizing data protection, data distribution processing
Module.
Background technique
Disaster tolerance (DR) and backup (BR, Backup) are two kinds of important methods of field of storage data protection.Disaster tolerance refers to
One or more sets identical data disaster tolerance systems are established in strange land, when storage system suffers natural disaster, war, earthquake etc. is various to resist
Natural calamity when, disaster tolerance system can maintain the continuity of availability of data and business.Backup refers to the data of storage system
It backs up in local standby system, due to being in local, for strange land, data synchronizing speed quickly, but can not be resisted
Destruction of the natural calamities such as natural disaster to data.Local backup system is for reasons such as virus attack, artificial maloperation, software errors
Caused by corrupted data can play a very good protection, long-distance disaster system is for the local number as caused by force majeure
Critical effect can be played according to damage.
For some important data, disaster tolerance system should be disposed in strange land, while need to be backed up locally.When depositing
When storage system causes file or corrupted data due to artificial maloperation or poisoning intrusion, local different backup point can be used
Data carry out fast quick-recovery.Current most storage equipment, can provide the function of backup and disaster tolerance, however, there are following
The limitation of two aspects:
A kind of situation is to store equipment the data on a direction can only be supported synchronous, can not be simultaneously by data distribution to two
Set or the other storage equipment of more sets；
Another situation is that when wherein it is a set of backup or disaster tolerance equipment on data opposite direction be synchronized to storage equipment when, no
Data can be synchronized and be write in other backups or disaster tolerance equipment, cause to store in the data and backup or disaster tolerance equipment in equipment
Data occur inconsistent, if it is consistent to reach data again, it is synchronous with data to re-start deployment, greatly reduces
The availability of backup and disaster tolerance system.
Summary of the invention

Fig. 5 is backup implementation diagram provided by the embodiments of the present application.As shown in figure 5, can on local standby system
To create a duplicate volume, storage volume in the size and storage system of duplicate volume it is in the same size.It is same that full dose is carried out for the first time
Step, subsequent all synchronizations all use increment synchronization mode, it is each it is subsynchronous it is complete all create a snapshot for duplicate volume, in this way,
The data backup collection with different time points is generated to storage volume.
It is as follows for generating the implementing procedure that more time points back up to storage volume:
The first, when disposing backup strategy to storage volume, the duplicate volume of a same size is created on standby system, and is built
Backup relation between vertical storage volume and duplicate volume distributes the bitmap of a characterization source volume data change for storage volume, number is arranged
According to synchronous strategy；
The second, the T0 moment, storage volume carries out full dose data to duplicate volume for the first time and synchronizes, i.e., the data of storage volume are complete
It is synchronized to duplicate volume, after synchronously completing, creates a snapshot S0 to duplicate volume, and removes the bitmap of storage volume, S0 is to store
Roll up the valid data at T0 moment；
The variation of each block number evidence is all recorded in bitmap in third, storage volume, according to the synchronization policy of setting, T1 moment
It is synchronous to need to carry out data again, only needs that the incremental data for being will be marked to be synchronized to duplicate volume in bitmap at this time；It synchronously completes
Afterwards, it removes bitmap and creates the valid data that another snapshot S1, S1 are then the storage volume T1 moment to duplicate volume；
4th, and so on, according to data synchronization strategy, the Backup Data of different time points can be generated for storage volume.
When sometime there is exception since artificial maloperation or other reasons cause in storage volume data to be damaged
When, such as file is accidentally deleted, at this time a last time can be selected by all BACKUP TIME points on inquiry local backup volume
Backup point carry out data recovery.
Fig. 6 is another example schematic diagram of the embodiment of the present application.As shown in fig. 6, the Backup Data S1 at selection T1 moment is anti-
To being restored to storage volume.In the present embodiment, duplicate volume initiates data write request, wherein carrying the number to be restored to storage volume
According to the information and source-information of the storage volume of, data to be written, source-information can serve to indicate that the data write request
Standby system where duplicate volume or duplicate volume；Data processing unit in storage system can be according to the number received
According to write request, the storage volume of data to be written is determined, and according to the backup disaster tolerance attribute of the storage volume, determine the corresponding storage
Data can be only synchronously written on disaster tolerance volume and storage volume by the disaster tolerance volume of volume deployment, then, file distributing unit, without
Duplicate volume is written.
