[0003] Since CDP will continuously monitor and back up data changes, a large amount of backup data will be generated during CDP backup, which will occupy too much backup storage space and eventually lead to overflow of backup storage space
When the backup storage space overflows, the backup service will go wrong, such as backup failure or backup data loss, which reduces the stability of CDP backup

The invention discloses a continuous data protection backup management method, computer equipment and a storage medium, and the method comprises the steps: if a backup storage space corresponding to a CDP overflows, determining a plurality of target files in a plurality of backup files of the backup storage space; acquiring data importance levels and backup time points of the plurality of target files; determining an importance degree value of the target file according to the data importance level and the backup time point; determining a to-be-deleted file in the plurality of target files according to the importance numerical value; and deleting the to-be-deleted file to increase the residual storage capacity of the backup storage space. According to the embodiment of the invention, when the backup storage space overflows, a part of backup files are deleted, so that the residual storage capacity is increased, the stability of CDP backup is improved, and the backup files are deleted according to the importance levels and the backup time points of the backup files, so that the backup files are deleted more reasonably, and important data are prevented from being deleted by mistake.
Description
technical field [0001] The present application relates to the technical field of continuous data protection, and in particular, to a backup management method, computer equipment and storage medium for continuous data protection. Background technique [0002] CDP (Continuous Data Protection) is a continuous protection technology for files. The system administrator does not need to pay attention to the data backup process, but simply selects the data backup time point that needs to be restored after a disaster occurs, and can realize the rapid data recovery technology. CDP can provide granular recoverable objects for an unlimited number of variable recovery points, enabling data recovery at any point in time in the past. [0003] Since CDP will continuously monitor and backup data changes, a large amount of backup data will be generated during CDP backup, occupying too much backup storage space, and eventually leading to overflow of backup storage space. When the backup stor...
