Problems solved by technology

[0004] However, the existing archiving time window is generally equal to the backup time window and is fixed, which will cause a certain degree of waste of resources, such as: the central processing unit (Central Processing Unit; CPU for short) and memory resources used for archiving The waste of the archive and the archiving time window and the backup time window are too small to consume disk space
At the same time, it also reduces the speed and efficiency of backup and archiving

Embodiment Construction

[0027] figure 1 It is a flowchart of an embodiment of the data processing method of the present invention, such as figure 1 As shown, the execution subject of this embodiment is a data processing device, then the method includes:

[0028] Step 101. Acquire a first time window corresponding to a first storage medium.

[0029] In this embodiment, the time window refers to the time interval between adjacent storage times.

[0030] In this embodiment of the present invention, the first storage medium may correspond to multiple time windows. When the first storage medium is preset with multiple time windows, one of the time windows is obtained as the first storage medium corresponding to the first time window. Time Window. Specifically, one of multiple time windows may be selected as the first time window corresponding to the first storage medium according to specific user requirements or other conditions.

[0031] Step 102 , every first time window, trigger the first storage m...

Abstract

The present invention provides a data processing method and system. The method includes acquiring a first time window corresponding to a first storage medium; every time the first time window is triggered, the first storage medium is triggered to acquire and store the first time window corresponding to the original data. Class incremental data, and record the first storage time corresponding to the first type of incremental data; obtain the second time window corresponding to the second storage medium; every second time window, will be stored in the first storage medium, and increase Merge all first-type incremental data whose age is greater than the first preset time period to generate second-type incremental data, and migrate the second-type incremental data from the first storage medium to the second storage medium , and then record the second storage time corresponding to the second type of incremental data; wherein, the second time window is greater than the first time window; and the performance of the second storage medium is lower than that of the first storage medium.

Description

technical field [0001] The invention relates to data backup and archiving technology, in particular to a data processing method and system. Background technique [0002] In data center applications, in order to prevent business data from being damaged, data is usually protected by means of backup. Currently, there are mainly two backup methods: full backup and incremental backup. Among them, the working principle of the full backup is to back up the files or disk partitions that need to be backed up at regular intervals. The working principle of incremental backup is to back up the changed parts of files or disk partitions that need to be backed up every once in a while. [0003] In addition, after the recent data backup, a large number of users need to archive and save the long-term data. The copy data to be backed up will be copied from high-speed storage media (higher-speed disk or tape) according to the age of the data and other factors. ) to a secondary storage mediu...
