[FreeFileSync] Open Source Super Easy-to-use Data Backup and Synchronization Tool [Windows]

As a computer worker, the importance of data is self-evident, so regular backup is the basic habit of each of us.

When it comes to data backup, for ordinary people, the best choice is NAS, but not everyone has this condition. Even if there is NAS, it is not very good to operate on the computer of the unit. Had to back up manually. But manual backup is really inconvenient. For example, as time increases, more and more things are backed up, and we will forget which ones have been copied; and after some files have been updated and modified, we forget to go. Backed up; the result of this is that errors or omissions will inevitably occur in the end, which is very unreliable!

There will be a portable version to choose from during the installation process, but we can choose the first local installation. There may be some advertisements, but the usage is the same. Of course, if you have the conditions, you can also donate to the developers, this is free~~

【FreeFileSync】can automatically set the language interface according to the system. It can be seen that its interface is relatively easy to understand, all in Chinese, and very friendly.

It is very simple to operate. Select the folder to be backed up in the left window; select the backup destination folder in the right window (the destination folder I back up directly selects the mobile hard disk mounted on the router ), all I need to do is Back up the folder selected on the left to the mobile hard disk that I mounted on the router.

Click the green gear button to enter the backup settings:

As for the synchronization method, this depends entirely on your needs.

Mirror: We generally choose this. As the name implies, it is to keep the target folder (right) exactly the same as the source folder (left). If files are added or modified in the source folder, the target folder is also added and modified. If files in the source folder are deleted, they will also be deleted in the destination folder.
Two-way: Similar to mirroring, the difference is that mirroring is only from left to right, and it can be from left to right or right to left in both directions. In other words, if the folder on the right is changed, the folder on the left is also modified.
Update: Incremental backup, only updates added and modified files, not deleted files. The difference between it and mirroring is that if the files in the left folder are deleted, the files in the right folder will not be deleted. What I need today is this kind of backup requirement.+

As for the settings for deleting files, it is up to you. There is no problem if you need to throw them in the recycle bin or delete them permanently.

There is also a display diagram during the synchronization process, which is very intuitive!

In fact, it’s very simple to use, just one sentence in a nutshell: select the original file and the target file, and click Sync.

Of course, what I demonstrated today is only the most basic local backup, it has many more powerful functions waiting for you to experience and explore after installation~
