Problems solved by technology

[0004] The current popular disaster recovery and backup solutions, such as disk array cabinets or NAS, SAN, the main problem is the high price, and the cost of building disk array cabinets is quite high, even for foreign medium-sized enterprises. In the case of NAS and SAN backup methods, once remote data is damaged, enterprises are often prone to unnecessary losses due to high recovery costs
However, a single cloud storage is slow, and once a single cloud provider server fails unexpectedly, it can cause serious cloud security incidents

Embodiment Construction

[0046] The above and other technical features and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0047] Such as figure 1 As shown, a multi-cloud security storage dynamic balance backup method includes the following steps:

[0048] S100: Split the initial file into multiple original data blocks according to requirements;

[0049] The I / O stream can be used to read the size of the initial file to be split first, and split the initial file according to the needs. The splitting process calculates the size of each scattered file and divides the file into multiple original data blocks. . If it is divided into five data blocks, they are recorded as A, B, C, D, and E respectively; the corresponding data block sizes are 8, 4, 6, 3, and 5 data units respectively.

Abstract

The invention provides a multi-cloud security storage dynamic balance backup method. The method comprises the steps of uploading a plurality of original data blocks to at least two cloud storage service nodes; backing up the original data blocks in each cloud storage service node; if a cloud node has a fault and the original data blocks and the backup data blocks stored in the node are lost, looking for backup data or original data corresponding to lost data in other cloud nodes, and backing up the found backup data and original data again, wherein the data blocks backed up again are stored inany other cloud storage service node which does not comprise the same or similar data blocks; and if the faulty cloud storage service node is restored or replaced with a new cloud storage service node, migrating the data blocks backed up again to the restored cloud storage service node or the new cloud storage node. By adopting a dynamic adjustment mechanism, hot backup and replacement of wrong cloud nodes can be realized, so that data block backup is more reliable.

Description

technical field [0001] The invention relates to the technical field of cloud storage, in particular to a multi-cloud security storage dynamic balance backup method and system. Background technique [0002] With the advent of the era of cloud computing and cloud storage, a large amount of data is generated every moment, a large part of which is meaningful and needs to be stored within a certain period of time or permanently. Because the cost of storing a large amount of data locally is too high, it is easy to lose. At present, a large amount of data has gradually adopted cloud storage services to realize data disaster recovery and backup. [0003] Disaster Recovery means that data can still be recovered through certain methods after being damaged by various disasters. [0004] The current popular disaster recovery and backup solutions, such as disk array cabinets or NAS, SAN, the main problem is the high price, and the cost of building disk array cabinets is quite high, eve...
