Embodiment Construction

[0023] The data backup method provided in the embodiment of this application can be adapted to figure 1 As shown in the system, the system may include a device 10 for generating a data backup policy and a system 11 to be backed up. Wherein, the system to be backed up includes a device to be backed up 110 and a host device 111 , the device to be backed up 110 runs on the host device 111 , and a backup client is installed on the host device 111 . The device 10 for generating the above-mentioned data backup strategy is used to generate the backup strategy. Based on the generated backup strategy, the backup client obtains the data of the device to be backed up 110 from the storage library (the storage library may be a disk array) through the backup agent interface on the host device 111. The data is sent to the backup server, so as to realize the data backup of the device 110 to be backed up.

Abstract

The invention provides a data backup method and device, equipment and a storage medium. The method comprises the steps: obtaining a data increment of a to-be-backed-up device at a current backup moment relative to a previous backup moment, a data volume at the current backup moment, a data volume at the previous backup moment, and a resource quantity of a host device at the current backup moment, the to-be-backed-up equipment runs on the corresponding host equipment, and a backup terminal is installed on the host equipment; according to the data increment, the data volume at the current backup moment, the data volume at the previous backup moment and the resource quantity of the host equipment at the current backup moment, determining a backup strategy of the to-be-backed-up equipment at the current backup moment, the backup strategy comprises at least one of a to-be-backed-up device disk file merging direction, a disk file merging depth and selection of a target host device; According to the backup strategy, sending an instruction for backing up the to-be-backed-up device to a backup terminal in the target host device. According to the method, the data backup success rate can be improved, and the data backup duration is shortened.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data backup method, device, equipment and storage medium. Background technique [0002] As we all know, data backup is an important means to prevent data loss and improve data security. Taking the data backup of the virtualized data center as an example, the data backup function of the virtual machine is essential. This backup function can prevent the backup data from being used when the disk of the virtual machine is abnormally damaged, the data on the disk is lost, or the user misuses it. Restore the data of the virtual machine. In traditional technologies, data backup strategies are usually set by users based on experience. However, the traditional method will lead to an unreasonable setting of the backup policy, resulting in a low success rate of data backup and a long time spent on data backup. Contents of the invention [0003] The present application pro...
