Problems solved by technology
However, due to the limited network bandwidth, when multiple volumes perform cloud backup at the same time, it will inevitably cause multiple volumes to rob bandwidth resources, thereby reducing the upload speed. Time can be uploaded, so it will seriously affect the user's experience and cannot meet the user's application needs

The invention discloses a bandwidth allocation method and a related device. The method comprises the steps: judging whether the number of volumes to be subjected to cloud backup at the same time is greater than the length of a priority backup queue or not: if not, adding the volumes to a priority backup queue, and allocating the total network bandwidth to the volumes in the priority backup queue according to a preset bandwidth allocation strategy; if yes, according to the access popularity of each volume, adding the volume with the highest access popularity and the total number equal to the length of the priority backup queue to the priority backup queue; allocating the network bandwidth of the first percentage to the volume in the priority backup queue according to a preset bandwidth allocation strategy, and allocating the network bandwidth of the second percentage to the volume outside the priority backup queue, wherein the first percentage is greater than the second percentage, andthe sum of the first percentage and the second percentage is 100%. According to the method, it can be guaranteed that volumes needing to be backed up preferentially can obtain more bandwidth resources, and therefore the purpose of preferentially completing backup is achieved.
Description
technical field [0001] The present application relates to the technical field of cloud backup, and in particular to a bandwidth allocation method; it also relates to a bandwidth allocation device, equipment, and a computer-readable storage medium. Background technique [0002] In the field of storage, cloud backup is a hot technology direction. The so-called cloud backup refers to backing up the data on the local storage system to the server of the cloud vendor, so as to backup data and save local disk space. Wherein, the backup unit of the cloud backup is a volume. The so-called volume is a piece of storage space divided after disk virtualization. Cloud backup is to upload all the data in the volume when the backup is started to the cloud. However, due to the limited network bandwidth, when multiple volumes perform cloud backup at the same time, it will inevitably cause multiple volumes to rob bandwidth resources, thereby reducing the upload speed. It takes time to comp...
