[LINUX] Install rsync on CentOS8 (version check) and file backup (synchronization)

First, install rsync and check the version

Installed below. (It seems that dnf has become the standard for installation from CentOS 8)

command


dnf -y install rsync

After the installation is complete, check the version below.

command


rsync --version

First, check the operation of 1 file copy

Command to copy the "/from/test1.txt" file to the "/ to /" folder. However, ** only the operation check ** is done without actually copying.

command


rsync -vn /from/test1.txt /to/

The result looks like this. (File is not copied) image.png Before you get used to it, you should add `` `-vn```.

Let's take a look at the options

command


rsync -help

result… image.png image.png (The total is about twice as much as this image ...)

For now, just remember the option to mirror the folder

I want to make the contents of the "/ to" folder the same as "/ from"! That option.

command


rsync -acv --delete /from/ /to/

When synchronizing folders, be careful not to forget to add "/" at the end of the copy source file path. If you do not add it, a "/ to/from" folder will be created and copied into it ...

Serpentine

I checked using Docker Desktop this time as well.
