TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after duplicate iCloud sync files nearly filled a database server. As of November 1, 2026, the NAS has four hard drives and an NVMe SSD installed but is not connected or configured; its planned backup safeguards have not been tested.
ThorstenMeyerAI.com has bought a UGREEN NASync DXP6800 Pro to add local backup storage and a separate space for AI-related containers and test databases, after duplicate files in an iCloud sync folder nearly filled a database server. The NAS has been equipped with four 16 TB hard drives and an NVMe SSD, but it is not yet connected to the network or configured, and the proposed safeguards have not passed testing.
Publisher Thorsten Meyer said a database server had fallen to 2% free disk space on September 17 after two machines uploaded database dumps with the same filename to an iCloud folder. The service produced 29 conflict copies, according to Meyer. On October 29, a later cleanup job also timed out while trying to remove old copies from the folder. Meyer said these incidents prompted the decision to stop treating sync as a backup system.
The planned setup uses four Seagate IronWolf Pro 16 TB drives in RAID 6, which Meyer estimates would provide about 32 TB of usable capacity while tolerating the failure of two drives. An NVMe SSD would sit in a separate storage pool for containers and test databases. The NAS has six drive bays, leaving room to add drives later; filling all six with 16 TB drives in the same RAID arrangement would provide about 64 TB, according to the plan.
Meyer proposes three backup safeguards: separate non-admin accounts and storage quotas for each Mac, daily snapshots that those accounts cannot access or delete, and an encrypted offsite copy using restic to Backblaze B2 with Object Lock. The NAS will not host a live database change log, give AI agents administrator credentials, or be exposed to remote internet access. Meyer said two tests must pass before the device is accepted: Time Machine must work through a non-admin account, and snapshots must remain inaccessible to that account.

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 Layer for AI Backups
The report is a deployment plan, not evidence of a working NAS backup system. If the proposed setup passes its tests, it would give the operation a local copy that can be used for faster restores than downloading hundreds of gigabytes from cloud storage. It would also move test databases off a work laptop, where Meyer said a Docker virtual disk had grown to about 30 GB.
The distinction between synchronization and backup is central to the incident. A sync service can replicate changes, including unwanted duplicates or deletions. A local NAS could provide a separate recovery point, but it does not by itself protect against every risk: it cannot prevent a database server crash, and a local device would not protect data from every office-wide failure. The planned encrypted offsite copy is meant to add another layer.
The consequences for readers are practical rather than a product verdict. The article describes how one small operation intends to balance capacity, recoverability, quiet office hours and restricted access. Since the hardware is not running and the acceptance tests are outstanding, its performance and reliability in this environment remain unverified.

Why the Six-Bay Model
Meyer described an operation built around several Macs: one runs the main PostgreSQL database, another serves local AI models, and others handle publishing workflows and tests. Measurements taken October 6 put storage use at about 2.6 TB on the main desk machine, 744 GB on the database server, and 3.2 TB on the model server. Meyer said the current backup requirement is about 6 to 8 TB, much of the model-server data being downloadable again.
The choice of the DXP6800 Pro over a cheaper four-bay model was driven by room to expand, Meyer said. The product specifications cited in the article are from UGREEN and Seagate: the NAS has six SATA bays, two M.2 slots, two 10GbE ports, a 10-core Intel Core i5-1235U processor and 8 GB of DDR5 memory, expandable to 64 GB. Meyer said the equipment was purchased with personal funds; UGREEN did not supply or sponsor it, and the article contains no affiliate links. The piece is not presented as a review or long-term test.
“That was the day I stopped treating a sync service as a backup.”

Tests Still Await Network Setup
As of November 1, 2026, the NAS had been delivered and fitted with drives and an SSD, but had not joined the network. The two acceptance tests had not run, and the operation continued to use its existing backup process: local Time Machine disks on two Macs and an iCloud copy of the nightly database dump.
It is not yet known whether Time Machine will work with the planned non-admin accounts, whether snapshots will be protected as intended, or how quickly the NAS will restore the operation’s data. The published capacity figures describe the proposed RAID layout, not measured results from a configured device. No real-world noise, transfer-speed, uptime or recovery results are reported.
Acceptance Tests Before Rollout
The next step is to connect and configure the NAS, then run the two stated acceptance tests: verify a Time Machine backup using a non-admin account and confirm that the same account cannot view or delete daily snapshots. Meyer says the NAS will be returned if either test fails.
If the tests pass, the plan is to use the hard-drive pool for backups and the separate NVMe pool for containers and test databases, while scheduling disk-heavy work between 8 p.m. and 6 a.m. The encrypted offsite copy to Backblaze B2 is also part of the intended design. Meyer said he plans to publish actual results after the system is running; until then, the setup remains a proposal rather than a tested deployment.
Key Questions
Is the UGREEN DXP6800 Pro already backing up the operation?
No. The NAS has been delivered and equipped, but as of November 1, 2026, it was not connected to the network or configured. Backups were still using local Time Machine disks and an iCloud copy of the nightly database dump.
Why did Meyer decide to buy a NAS?
Meyer said duplicate iCloud conflict copies pushed a database server down to 2% free disk space, and a later cleanup job timed out. The NAS is intended to provide a local backup destination and storage for test databases.
How much storage is planned?
The proposed RAID 6 pool uses four 16 TB drives and is estimated to provide about 32 TB usable capacity. The six-bay device could reach about 64 TB with six 16 TB drives in the same RAID arrangement, according to the article’s calculations.
What must happen before the NAS is accepted?
Two tests must pass: Time Machine must work using a non-admin account, and daily snapshots must remain inaccessible to that account. Meyer says the device will be returned if either test fails.
Will the NAS replace offsite backups?
No. The plan includes an encrypted offsite copy to Backblaze B2 using restic and Object Lock. The NAS is intended as a local layer, not as a replacement for a separate offsite copy.
