Backing Up the Original UGREEN DXP4800 Plus System Image Using Clonezilla

If you’re planning to tinker with your UGREEN NAS, whether that’s installing a different operating system or experimenting with alternative configurations, it’s absolutely worth taking a full backup of the factory-shipped system image first. Unfortunately, UGREEN doesn’t currently provide downloadable UGOS images, so if you overwrite yours, you’re out of luck unless you’ve cloned it beforehand.

To make life easier, I put together a video showing the simplest and least painful way to back up the original OS image from a UGREEN DXP4800 Plus using Clonezilla.

Before anyone asks: no, this video doesn’t include instructions on how to download Clonezilla or burn it to a USB stick. If you’re not already familiar with that process, you probably shouldn’t be attempting this sort of low-level system backup in the first place.

What’s Covered in the Video

The video walks through the key parts of the process:

1. Factory Resetting the NAS

To ensure the backup is as “clean” as possible, the NAS is restored to its factory state. This is optional, but strongly recommended if your aim is to preserve the original UGOS environment exactly as shipped.

2. Booting from the Clonezilla ISO

Clonezilla is a brilliant tool for full-disk imaging, and it boots perfectly fine on the DXP4800 Plus. The video shows how to get the NAS to load from the USB stick and launch Clonezilla.

3. Backing Up the Internal Drive to an External USB Drive

Rather than stripping the NAS down and swapping drives, a level of faff I simply couldn’t be bothered with, I opted to plug an external drive directly into the NAS. Clonezilla happily writes the disk image to that drive without needing any hardware disassembly.

This means you can create a safe, restorable copy of the original UGOS installation without touching the internal hardware.

Why I Recorded This

My plan is to install a different operating system (TrueNAS), but without an official UGOS image available to download, I wanted to make sure I had a reliable route back to stock if needed. Clonezilla makes that easy, and the method shown avoids unnecessary teardown work.

If you’ve got a DXP4800 Plus and you’re about to venture outside the stock OS, taking a proper backup is the smartest thing you can do. Hopefully this guide and video save you some hassle down the line.
