TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after duplicate cloud-synced database dumps nearly filled a server. The NAS has four hard drives and an NVMe SSD installed but is not yet connected or configured; its proposed backup design still needs to pass two tests.
ThorstenMeyerAI.com has bought a six-bay UGREEN NASync DXP6800 Pro after duplicate database dumps in an iCloud folder left one server with just 2% free disk space. The device has been fitted with four hard drives and an NVMe SSD, but it is not yet on the network or configured, so the backup system described in the report remains a plan rather than a tested result.
Thorsten Meyer said that on September 17, two machines uploaded database dumps with the same filename to one iCloud folder. The service retained conflict copies, eventually creating 29 duplicates and nearly filling the database server. The report says a separate cleanup attempt on October 29 also stalled when deleting old copies timed out while iCloud was busy.
The NAS is intended to provide local storage for backups and test databases. The planned arrangement uses four Seagate IronWolf Pro 16 TB drives in RAID 6, which Meyer estimates would provide about 32 TB usable capacity. An NVMe SSD would form a separate pool for containers and test databases. These are proposed settings; neither pool has been configured or tested.
The report says the NAS and storage were bought with the author’s own money. UGREEN did not provide a sample or sponsor the article, which Meyer says is not a product review or long-term test. The article attributes specifications to UGREEN and Seagate and fleet measurements to the author’s own records.

What UGREEN lists for the NASync DXP6800 Pro, and how we plan to fill it.
How we fill it
Delivered and equipped; the setup is our plan (1 Nov 2026)
Bays 1–4: Seagate IronWolf Pro 16 TB, RAID 6, Btrfs → ≈ 32 TB usable, any two drives may fail. Bays 5–6: free for growth. M.2 slot 1: the NVMe SSD (ordered: Samsung 990 Pro 1 TB) as its own fast pool. Slot 2: free. Six 16 TB drives in RAID 6 would give ≈ 64 TB.
What else UGREEN lists
From the product page, not measured by us
- Separate 128 GB SSD for the operating system, UGOS
- RAID: JBOD, Basic, 0, 1, 5, 6, 10
- 1× PCIe x4 · 2× Thunderbolt 4 · 8K HDMI · SD card reader
- Power: 43.07 W drives in use · 24.91 W drives in hibernation
- Stated maximum: 208 TB with 32 TB drives · 3-year warranty
Why six bays: with RAID 6, two drives always hold parity. In four bays that leaves half the raw space usable; with all six bays filled it becomes two thirds.

A Local Copy for Faster Recovery
The purchase reflects a practical distinction between file synchronization and backup: a sync service can replicate deletions, conflicts or other unwanted changes rather than preserve a clean recovery point. Meyer says a local NAS could make large restores faster than downloading them from cloud storage, while a separate offsite copy would still be needed if equipment or data at the office were lost.
The reported storage need is relatively modest: measurements taken October 6 put the operation’s current backup requirement at about 6 to 8 TB. The six-bay unit is intended to leave room to expand without replacing the initial drives. That extra capacity comes with costs and operational trade-offs, including hardware expense, drive noise and the need to manage accounts, snapshots and offsite copies. The report does not yet establish that the planned system will work as intended.

Why Six Bays Made the Cut
Meyer describes a small operation using several Macs for a publishing system, local AI models, content pipelines and testing. On October 6, the main desk machine held about 2.6 TB, the database server about 744 GB (including a database of roughly 293 GB), and the model server about 3.2 TB, much of it replaceable model files.
The initial plan is to use four of the six drive bays, leaving capacity to add drives later. Meyer says the DXP6800 Pro was chosen over a less expensive four-bay model for that expansion room. The report lists UGREEN-stated specifications including a 10-core Intel Core i5-1235U, two 10GbE ports, two M.2 slots and 8 GB of DDR5 memory expandable to 64 GB. A full set of six 16 TB drives in RAID 6 is estimated in the article to provide about 64 TB usable.
“That was the day I stopped treating a sync service as a backup.”

Two Tests Before Rollout
The central unknown is whether the planned setup will pass its acceptance tests. Meyer says the NAS is not yet connected to the network, and the tests for Time Machine using a non-admin account and snapshots that account cannot access or delete have not run. If either test fails, the report says the hardware will be returned.
Other details also remain unverified in day-to-day use, including actual restore times, noise, drive sleep behavior and whether the proposed backup schedule works reliably. The existing backups still rely on local Time Machine disks for two Macs and an iCloud copy of the nightly database dump. No results are available yet from the proposed encrypted offsite backup to Backblaze B2.
Acceptance Tests and Backup Changes
The next step is to put the NAS on the network and test the two stated conditions: Time Machine backups using a non-admin account, and daily snapshots that the account cannot see or delete. Meyer says the hardware will be returned if either test fails. If they pass, the planned setup adds encrypted offsite copies through restic to Backblaze B2, with Object Lock configured to resist deletion.
The proposed schedule places disk-heavy work between 8 p.m. and 6 a.m., with drives intended to sleep during the workday. The author also says the system will not host a live database change log on spinning disks, give AI agents administrator credentials, allow remote internet access, or treat UGREEN’s cloud mirror as the offsite backup. Meyer says he will report back with results after the system is running.
Key Questions
Is the UGREEN NAS already running?
No. The report says the NAS has been delivered and equipped with four hard drives and one NVMe SSD, but it is not yet on the network or configured.
What storage setup is planned?
The proposed arrangement uses four 16 TB Seagate IronWolf Pro drives in RAID 6, with an estimated 32 TB usable, plus a separate NVMe pool for containers and test databases. These figures describe the plan, not a completed setup.
Why did Meyer buy a six-bay model?
Meyer says the extra bays offer room to add drives later without replacing the initial set. He chose it over a cheaper four-bay model for that expansion capacity.
What caused the server to run low on disk space?
Two machines uploaded database dumps with the same filename to an iCloud folder. The service retained 29 conflict copies, leaving the server with 2% free space, according to the report.
What has to happen before the system is adopted?
The NAS must pass tests for Time Machine backups using a non-admin account and for snapshots that the account cannot access or delete. Meyer says the device will be returned if either test fails.
