Abstract
The present invention relates to a kind of computer disk data sustainable protection method, the method carries out mirror-image copies and is rolled up to sustainable protection by sustainable protection client to local volume, for mirror image protection volume, countershaft carries out time point establishment volume shadow copy copy to the data of different time points on time, during normal work, the data of all local volumes can all be preserved with log recording, time point volume shadow copy according to time shaft adds log recording to complete continuous data protection, log recording can be added to recover to take office a time point by snapshot during recovery, for the utilization rate of hoist capacity, the method is characterized in only to be written into correspondence volume shadow copy copy the last time to this delta data when creating volume shadow copy copy every time, other data retain copy using the mode that has of index point.
Description
Technical field
Patent of the present invention is related to computer disaster tolerance to protect field.
Background technology
The epoch of information explosion, data volume is all constantly linearly increasing, the nowadays dynamic TB or more of then going up of data
Up to PB；Simultaneously with the dispersion and refinement of information unit, in the case of same quantity of data, data text
Part is more or size of single file is smaller.The data disaster tolerance protection of so huge data volume,
And increasing data volume and less and less single file, the disaster tolerance of data is protected
Backup and recovery window are all huge challenges.Disk unit, the protection of different application are directed to simultaneously,
All it is a kind of challenge to conventional backup, how solves the protection higher level that these challenges are all related to data
Other or new direction.
Patent of invention content
Patent of the present invention is related to a kind of computer disk data sustainable protection method, and the method is by continuing
Protection client carries out mirror-image copies and is rolled up to sustainable protection to local volume, for mirror image protection volume temporally
Axle carries out time point establishment volume shadow copy copy, during normal work, Suo Youben to the data of different time points
The data of ground volume can all be preserved with log recording, and log recording is added according to the time point volume shadow copy of time shaft
To complete continuous data protection, log recording can be added to recover to take office a time point by snapshot during recovery,
For the utilization rate of hoist capacity, the method is characterized in only by upper one when creating volume shadow copy copy every time
The secondary delta data to this is written to correspondence volume shadow copy copy, and other data are had using index point
Mode retains copy.
Brief description of the drawings
Fig. 1 is a kind of computer disk data sustainable protection method structural representation of patent of the present invention.
Specific embodiment
In order that the object, technical solution and advantage of patent of the present invention become more apparent, below in conjunction with

A kind of computer disk data sustainable protection method, it is characterised in that the method includes lasting guarantor
Shield volume (10), sustainable protection client (11), local volume (12), time shaft (13), volume
Snapshot copy (14) and log recording (15).
A kind of computer disk data sustainable protection method, it is characterised in that user passes through sustainable protection
Sustainable protection volume (10) is configured to locally roll up client (11) mirrored volume of (12),
A kind of computer disk data sustainable protection method, it is characterised in that the reality of continuous data protection
It is now to roll up (10) on the basis of time shaft (13), according to sustainable protection client by sustainable protection
The volume data creation of different time points is volume shadow copy copy (14) by the strategy at end (11), while institute
The data write-in for having local volume (12) is all got off by log recording (15), to complete different time
The snapshot copy (14) of point only retains last updating the data to this, and other data are by index
Pointer is preserved.
The preferred embodiment of patent of the present invention is the foregoing is only, is not intended to limit the invention specially
Profit, all any modification, equivalent and improvement made within the spirit and principle of patent of the present invention
Deng should be included within the protection domain of patent of the present invention.
