Problems solved by technology

Since the entire block storage is backed up each time, the amount of data to be backed up is relatively large. When a large number of block storages need to be backed up in a single backup cycle, the amount of backup data in a single backup cycle will become very large. There are at least the following disadvantages: first, there will be high requirements on the capacity of the target storage; second, the backup cycle will not be small; third, it will occupy the storage bandwidth and network bandwidth of the business, and then affect the online business; Fourth, this backup method is not flexible enough in the adjustment of the backup strategy

Abstract

The present invention relates to an adaptive backup system for block storage based on a cloud environment, comprising a backup task scheduler and a set of block devices to be backed up, wherein the backup task scheduler is used to control the backup tasks of the block devices to be backed up in the system Execute and adaptively adjust the backup strategy; the set of block devices to be backed up includes a plurality of block devices to be backed up, and the block devices to be backed up perform a full backup operation according to the corresponding full backup cycle, and at two adjacent full backup time points Perform incremental backup operations according to the corresponding incremental backup cycle. The invention reduces the amount of backup data and improves the balance and flexibility of backup task distribution.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a block storage self-adaptive backup system based on a cloud environment. Background technique [0002] With the development of cloud computing technology, cloud computing has entered all walks of life. In some cloud environments, resource changes are infrequent, but the importance of data is very high. Therefore, it becomes particularly important for data backup in a cloud environment. However, data backup in these cloud environments currently mainly requires cloud users to implement data backup at the business layer. This has the advantages of small backup volume and relatively flexible backup, but the disadvantage is that it has high requirements for cloud users. Do not have this ability. Judging from the current situation, most applications in the cloud environment do not have data backup at the business layer. Therefore, the backup of the platform layer becomes very im...
