[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 present application discloses a backup management method, computer equipment and storage medium for continuous data protection. The method includes: if the backup storage space corresponding to the CDP overflows, determining a plurality of target files from among the backup files in the backup storage space ; Obtain the data importance level and backup time point of multiple target files; determine the importance value of the target file according to the data importance level and backup time point; Delete files to increase the remaining storage capacity of the backup storage space. In the embodiment of the present application, when the backup storage space overflows, part of the backup file is deleted to increase the remaining storage capacity, thereby improving the stability of CDP backup, and the backup file is deleted according to the importance level of the backup file and the backup time point, so that the backup The deletion of files is more reasonable to avoid accidental deletion of important data.
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...
