Problems solved by technology

[0007] 1. In the process of backing up data, due to the large amount of data, the backup time is too long, and the backup efficiency is low
[0008] 2. Store multiple copies of duplicate data, taking up a lot of disk space
[0009] 3. The original data is damaged before the backup, and the damaged data of the backup overwrites the correct data, resulting in invalidation of the backup data

Embodiment 1

[0088] Please refer to Figure 3-Figure 6 Shown are the structure diagram of the backup data directory of the first embodiment of the present invention, the schematic diagram of the initialization phase, the schematic diagram of the realization of the odd-numbered backup period, and the schematic diagram of the realization of the even-numbered backup period; Figure 3-Figure 6 As shown, the specific implementation process of the data backup method of the present invention is as follows:

[0089] A. Initialization stage:

[0090] a. From the server where the source data is located, back up the source data in full to the backup server to form a single-number cycle backup data DATA, command: rsync –avzP / path / to / DATA-source backup@bakserverIP: / path / to / DATA-BAK / DATA;

[0091] b. Perform a full backup of the odd-numbered period backup data on the backup server to form the even-numbered period backup data DATA-0T (where 0T refers to the backup date, ie DATA-0T=DATA-"%Y%m%d") ,command: ...

Embodiment 2

[0108] Please refer to Figure 7 Shown is a schematic diagram of the implementation of the backup method of the second embodiment of the present invention, such as Figure 7 As shown, the specific implementation process of the data backup method of the present invention is as follows:

[0109] A. Initialization stage:

[0110] a. From the server where the source data is located, back up the source data in full to the backup server to form the first backup data DATA; command: rsync –avzP / path / to / DATA-source backup@bakserverIP: / path / to / DATA-BAK / DATA;

[0111] b. Perform a full backup of the first backup data on the backup server to form the second backup data DATA-0T (where 0T refers to the backup date, ie DATA-0T=DATA-"%Y%m%d"), command :

[0112] rsync –avzP / path / to / DATA-BAK / DATA / path / to / DATA-BAK / DATA-0T;

[0113] b. Perform another full backup of the second backup data on the backup server to form the third backup data DATA-0’T (where 0T <0’T <1T), command: rsync -avzP / path / to / D...

Abstract

The invention relates to a backup method of data. The backup method comprises the following steps of S1, the initializing stage, wherein source data is subjected to full backup twice to form odd number cycle backup data DATA 0-T/DATA and even number cycle backup data DATA-0T; S2, odd number backup, wherein the source data is synchronized into last odd number cycle backup data to form the latest backup data DATA (2n+1)T, and n belongs to N; S3, even data backup, wherein the source data is synchronized into last even number cycle backup data to form the latest backup data DATA (2n)T, and n belongs to N. By means of the backup method of the data, on the basis of integrating the advantages and the disadvantages of three backup modes of the full backup, incremental backup and differential backup, an efficient and reliable backup mode is provided, it can be guaranteed that the data is safe and reliable, the manpower cost can also be saved to a certain degree, and the work efficiency is improved.

Description

Technical field [0001] The invention relates to the field of computer technology, in particular to a data backup method. Background technique [0002] With the continuous development of computer science and technology and the surge in data volume, the security of data has become crucial. As a basic disaster recovery method, data backup is an important part of data security. [0003] There are three commonly used backup methods: full backup, incremental backup and differential backup. Full backup takes up a lot of space; incremental backup data takes a long time to restore and is troublesome; differential backup restores faster but takes longer to backup. [0004] Among them, the implementation of differential backup is to perform a full backup first, and then perform a differential comparison with the full backup data each time a differential backup is performed, and then back up all files that have changed since the last full backup. See the specific implementation principle figu...
