A recommended method and system for data backup for storing user data in a storage device

Abstract

The present invention provides a data backup recommendation method and system for storing user data in a storage device. All of them perform backup recommendation for all currently unbacked user data in a high-level data group according to the current value of m in real time; Value, make backup recommendations for all the currently unbacked user data in the middle-level data group; according to the current value of q in real time, make backup recommendations for all the currently unbacked user data in the low-level data group; Every time when the ΔT is newly reached, backup recommendation is made to all the currently unbacked user data in the high-level data group according to the current value of M; Backup recommendation is made for the backed up user data; according to the current value of Q, backup recommendation is made for all currently unbacked user data in the low-level data group. The present invention is used to assist in improving the utilization rate of the storage device, and to reduce the user's equipment cost and maintenance cost.

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 cannot be overstated. The backup of user data is a common way in the storage field to protect data security, and its importance is also self-evident. [0003] At present, in the storage field, users often use snapshot technology to back up data, and often use timed snapshot technology to automatically and regularly back up data to achieve the purpose of data protection. However, every time a snapshot backup is performed, all data that has not been backed up on the storage is often backed up, and some data that can be backed up after a delay is also backed up, that is, each backup is often backed up some temporarily unnecessary data. However, as the storage device runs for a long time and the data backup capaci...

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
