Data synchronization between USB flash drives and hard disks in LINUX

Synchronization of U disk data and hard disk in LINUX-general Linux technology-Linux technology and application information. The following is a detailed description. File synchronization on different folders and data disks is a problem that people often encounter. For example, after I often finish my work on my office computer, I need to save it to a USB flash disk, I often work on my home computer, which involves how to synchronize the data. Of course, leaving a backup on one of the computers and a copy of the USB flash disk is also for data security considerations. In windows, you know that you can use the briefcase tool to synchronize some of your data. What about LINUX? Today, I found a software called unison, which is a good tool for data synchronization. It is very convenient to synchronize not only the USB flash disk and hard disk, but also the data on different computers through the network, it's super easy to use, and you don't need to use it for any reason. You just need to remember this software. It is in most LINUX software repositories, your Fedora only needs to execute yum install unison to install the software. The rest is to enjoy the convenience it brings.
