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 invention relates to a block storage adaptive backup system based on cloud environment, which comprises a backup task scheduler and a to-be-backed-up block device set. The backup task scheduler is used for controlling the execution of a backup task of a to-be-backed-up block device of the system and adaptively adjusting a backup strategy; the to-be-backed-up block device set comprises a plurality of to-be-backed-up block devices, the to-be-backed-up block devices execute full-amount backup operation according to the corresponding full-amount backup periods, and incremental backup operation is executed between two adjacent full-amount backup time points according to the corresponding incremental backup periods. According to the system, the backup data volume is reduced, and the balance and the flexibility of backup task distribution are improved.

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...
