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...
