Back up remote VPS (CentOS) data in batches on Windows host
BitsCN.com does not only need to back up MySQL after VPS, but also some independent site data needs to be backed up.
If there is a reliable third-party Linux host or cloud storage like Amazon, it is much simpler, and Linux-Linux backup is very convenient.
However, I want to run a backup every day or every week in my Windows 7 environment.
The general idea is as follows:
Connect to the VPS using plink.exe provided by Putty, run the backup, and log out;
Use pscp.exe, which comes with Putty, to copy the backup to the local machine;
Add a scheduled task and run it once every day/week to implement scheduled backup.

After the download is complete, the backup files generated on the server are not deleted, because the files are automatically cleared before the next backup.
Download and use
Download the file to your local machine, decompress it to a certain place, and modify the configuration items according to the preceding instructions;
Because the Key needs to be added to the local machine for the first SSH login, this step cannot be simply ignored. The feasible method is to load the Putty Session, but it is quite troublesome. it is simpler to run it once, we need to perform an SSH logon:
: Switch to the directory you extracted, such as D:/VPS /:
Cd/d D:/VPS/
: Modify the following parameters as needed.
Exe/plink.exe-C root@192.168.1.100-P 22-pw password
: Wait, and you will be prompted whether to add the Key to the list of hosts trusted by the local machine. enter yes.
Yes
: Now, enter some common commands to play with it and enter exit to exit.
Exit
Add a scheduled task according to the introduction in this article;
Manually execute the previously added scheduled task or observe an execution cycle to check whether the backup is valid.
To be improved
Like the previous script, it seems that there is still a lack of a function to automatically delete the backup several days ago. BitsCN.com
