Abstract

The present invention relates to hard disk data protection method under a kind of Linux server, it is by sustainable protection volume mapping to Linux server, by the LVM disk management instruments of Linux server system, local volume and sustainable protection volume are configured to mirror, again by installing sustainable protection client in Linux server, the tactful volume to sustainable protection that sustainable protection client passes through to configure carries out the protection of snapshot added-time countershaft, when sustainable protection volume produces snapshot, locking write request is issued to LVM by sustainable protection client, write request is unlocked again after completing snapshot, to realize the consistent available of protection data.

Description

Hard disk data protection method under a kind of Linux server
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 hard disk data protection method under a kind of Linux server, is by lasting guarantor Volume mapping is protected to Linux server, by the LVM disk management instruments of Linux server system, Local volume and sustainable protection volume are configured to mirror, then are continued by being installed in Linux server Protection client, sustainable protection client carries out snapshot and adds by the strategy for configuring to sustainable protection volume The protection of time shaft, when sustainable protection volume produces snapshot, is issued by sustainable protection client to LVM Locking write request, write request is unlocked after completing snapshot again, to realize protecting the consistent available of data.
Brief description of the drawings
Fig. 1 be patent of the present invention a kind of Linux server under hard disk data protection method structural representation Figure.
Specific embodiment
In order that the object, technical solution and advantage of patent of the present invention become more apparent, below in conjunction with Drawings and Examples, are further elaborated to patent of the present invention.It should be appreciated that this place is retouched The specific embodiment stated only is used to explain patent of the present invention, is not intended to limit the present invention patent.
Refer to Fig. 1, Fig. 1 be patent of the present invention a kind of Linux server under data in magnetic disk protection side Method structural representation.
Hard disk data protection method under a kind of Linux server, it is characterised in that the method is comprising lasting Protection client (10), sustainable protection client (11), write request (12), LVM (13), Local volume (14) and protection snapshot point (15).
Hard disk data protection method under a kind of Linux server, it is characterised in that sustainable protection rolls up (10) Mirror with local volume (14) is built by LVM (13), to realize real time data synchronization, Sustainable protection client (11) is rolled up (10) and carries out lasting number by the strategy for configuring to sustainable protection According to protection, protected mode is volume shadow copy added-time countershaft data (15), when protection creates snapshot, is continued Protection client (11) can ask LVM (13) to lock write request (12), after the completion of establishment snapshot, Sustainable protection client (11) can ask LVM (13) to unlock write request (12).
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.

Claims (2)

1. hard disk data protection method under a kind of Linux server, it is characterised in that the method is included Sustainable protection client (10), sustainable protection client (11), write request (12), LVM (13), Local volume (14) and protection snapshot point (15).
2. hard disk data protection method under a kind of Linux server according to claim 1, its It is characterised by, sustainable protection is rolled up (10) and built and the local mirror image for rolling up (14) by LVM (13) Relation, to realize real time data synchronization, sustainable protection client (11) is tactful right by what is configured Sustainable protection volume (10) carries out continuous data protection, and protected mode is volume shadow copy added-time countershaft data (15), When protection creates snapshot, sustainable protection client (11) can ask LVM (13) to lock write request (12), Create after the completion of snapshot, sustainable protection client (11) can ask LVM (13) to unlock write request (12).
