How to backup an external drive to a Synology NAS (Automatically)

I use an external SSD for all the video files I don’t want on my computer or Synology drive client (free).

Here’s how to do it, and why you might just stick to the method of copy and paste.

What is Synology Client Drive?

Synology Drive Client allows you to create regular or scheduled backup tasks to back up files on your computer to a Synology server. This software can also help you create versions of these files that can be restored or downloaded when needed.

Why you might not want to do scheduled backups

Anytime you’re using software to create schedule backups to a server, you’re going to experience problems. I like the fact that I don’t have to backup my files manually, but creating a backup makes the file location messy.

The software for Synology drive server is not user friendly, and I still haven’t found a way to backup more than one source. Like most software and apps, Synology does not update them regularly, so expect possible bugs.


At the end of the day, if you need scheduled backups, Synology client drive is the way to do it. It’s not the best software Synology has made, but it works. I still recommend doing manual backups. It’s just easier and creates a better file structure. I hope this was helpful.
