Data backup recommendation method and system for storing user data by storage equipment

Abstract

The invention provides a data backup recommendation method and system for storing user data by storage equipment, and the method comprises the steps: carrying out the backup recommendation of all non-backed-up user data in a high-level data group in real time according to the current value of m; according to the current value of n, carrying out backup recommendation on all the user data which arenot backed up currently in a medium-level data group in real time; according to the current value of q, carrying out backup recommendation on all the user data which are not backed up currently in a low-level data group in real time; when the latest value of Delta T is reached each time, carrying out backup recommendation on all the user data which are not backed up currently in the high-level data group according to the current value of M; according to the current value of N, performing backup recommendation on all the user data which are not backed up currently in the middle-level data group; and according to the current value of Q, performing backup recommendation on all the user data which are not backed up currently in the low-level data group. The method and the system are used for assisting in improving the utilization rate of the storage equipment and reducing the equipment cost and the maintenance cost of a user.

Description

technical field [0001] The invention relates to the field of storage devices, in particular to a data backup recommendation method and system for storing user data in a storage device. Background technique [0002] In the field of storage, the importance of user data is self-evident. The backup of user data is a common method used in the storage field to protect data security, and its importance is also self-evident. [0003] At present, in the field of storage, users often use snapshot technology to back up data, and often use timing snapshot technology to automatically and regularly back up data, so as to achieve the purpose of data protection. However, every time a snapshot backup is performed, all the data that has not been backed up on the storage are often backed up, and some data that can be backed up later are also backed up, that is, each backup is often backed up some temporary unnecessary backup data However, as the storage device runs longer and the capacity of...

AI Technical Summary

Problems solved by technology

However, every time a snapshot backup is performed, all the data that has not been backed up on the storage are often backed up, and some data that can be backed up later are also backed up, that is, each backup is often backed up some temporary unnecessary backup data However, as the storage device runs longer and the capacity of data backup increases, the backup data will soon occupy a large space of the storage device itself, reducing the utilization rate of the storage device

However, if the backup data is migrated to the third device, although the capacity problem of the storage device is solved, it also directly increases the user's equipment cost and maintenance cost
