Problems solved by technology

For an enterprise, the security of network data is extremely important. Once important data is damaged or lost, it will have a significant impact on the daily production of the enterprise, and even irreparable losses
[0003] The reasons for the destruction of disk data mainly include the following aspects: 1) Natural disasters, such as floods, fires, lightning strikes, earthquakes, etc., cause damage to the computer system, resulting in the destruction or complete loss of stored data; 2) System administrators and maintenance Misoperation of personnel; 3) Computer equipment

Example Embodiment

[0012] Hereinafter, the present invention will be further described in detail with reference to the drawings and implementation examples:

[0013] As described in the content of the invention, the system structure of the present invention mainly includes: a WEB management module, a terminal management module, a task manager, a database module continuous snapshot module, a data recovery module, and an IP SAN module.

[0014] In order to protect the local disk of the application server, the storage server first establishes a storage pool on the physical disk and allocates logical storage units in the storage pool; through the IP SAN setting, the logical storage unit can be set to target mapping and CHAP authentication.

[0015] The client connects to the logical storage unit of Target on the storage server through the iSCSI Initiator. Use disk management tools to mirror the local disk and the logical disk; format the disk with the required file system.

[0016] Select the logical storag...

Abstract

The invention provides a continuous data protection method based on continuous snapshots and a system. A disk or a copy of a logic storage unit can be acquired by snapshots, and a plurality of copiesof disk can be continuously acquired by snapshots so as to realize continuous protection on data. The storage unit can be restored to the previous state by rollback snapshots, or a new logic disk canbe generated by cloning snapshots for user mounting. By continuously storing the state of a storage tank through automatic snapshot technology, continuous protection on data can be realized; when an accident happens, normal system and data state can be rolled back rapidly, and data error caused by soft disasters such as incorrect manipulation, virus attack and the like can be avoided by selectingvalid historical state point data.

Description

technical field [0001] The invention relates to the computer field, in particular to a method for continuous data protection based on continuous snapshots. Background technique [0002] The 21st century is an information age, and electronic information is gradually replacing paper as the most important data storage method. Informatization has also gradually become an important part of core competitiveness from being a support for core competitiveness. For an enterprise, the security of network data is extremely important. Once important data is damaged or lost, it will have a significant impact on the daily production of the enterprise, and even cause irreparable losses. [0003] The reasons for the destruction of disk data mainly include the following aspects: 1) Natural disasters, such as floods, fires, lightning strikes, earthquakes, etc., cause damage to the computer system, resulting in the destruction or complete loss of stored data; 2) System administrators and maint...
