TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after duplicate iCloud sync files nearly filled a database server. As of Nov. 1, 2026, the NAS has four hard drives and an NVMe SSD installed but is not connected or configured; the proposed backup system and its safeguards have not been tested.
ThorstenMeyerAI.com says it has bought a UGREEN NASync DXP6800 Pro after repeated iCloud sync problems left one server with 2% free disk space. The network storage device is equipped with four 16 TB hard drives and an NVMe SSD, but as of Nov. 1 it has not been connected to the network or configured, so the proposed backup system remains untested.
The site’s owner, Thorsten Meyer, said 29 conflict copies of a database dump accumulated after two machines sent files with the same name to one iCloud folder. The incident occurred on Sept. 17. Meyer said a later backup job also failed to clear old copies after a cleanup process timed out while iCloud was busy. Those problems led him to stop treating a sync service as a backup destination.
The planned configuration uses four Seagate IronWolf Pro 16 TB drives in RAID 6, which Meyer estimates would provide about 32 TB of usable capacity and tolerate the failure of two drives without data loss. An NVMe SSD would form a separate pool for containers and test databases. The remaining two drive bays would leave room to expand; filling all six with 16 TB drives in the same RAID arrangement would provide about 64 TB, according to the site’s plan.
Meyer says protection would have three layers: separate, non-administrator accounts and quotas for Mac backups; daily snapshots that those accounts cannot access or delete; and an encrypted offsite copy sent with restic to Backblaze B2, with Object Lock intended to prevent deletion. None of these safeguards has yet been verified on the new device. The site says two acceptance tests—Time Machine backup using a non-admin account and snapshots protected from that account—must pass before it keeps the NAS.

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.

Why Local Restore Speed Matters
The purchase addresses a recovery and reliability problem, rather than a shortage of space for AI models. Meyer said the operation’s current backup requirement is about 6 to 8 TB. Measurements taken Oct. 6 showed about 2.6 TB in use on the main desk machine, 744 GB on the database server, and 3.2 TB on the model server; much of the latter consists of model files that can be downloaded again.
A local NAS could give the team a nearby copy to restore from, reducing dependence on downloads over its office internet connection. It also separates backup storage from the Macs being backed up. That distinction matters because a sync service can copy deletions or duplicate files along with wanted data. However, the NAS cannot prevent a computer crash or guarantee recovery by itself: its value depends on successful setup, protected snapshots and a separate offsite copy.
The plan also reserves the SSD for containers and test databases that currently run in Docker on Meyer’s laptop, where a virtual disk had grown to about 30 GB. Moving that work could free local resources, but the claimed benefits to memory use, fan noise and day-to-day performance have not yet been measured.

From Sync Conflicts to Six Bays
Meyer described the equipment as serving a small publishing and AI operation, not a data center. Several Macs run continuously: one hosts the main Postgres database, another serves local AI models, and others support content pipelines and testing. The site says the database itself measured about 293 GB when it took its Oct. 6 inventory.
The choice of the six-bay DXP6800 Pro over a cheaper four-bay model was based on expansion capacity, Meyer said. According to specifications he attributed to UGREEN, the device has a 10-core Intel Core i5-1235U processor, two 10GbE ports, two M.2 slots and 8 GB of DDR5 memory expandable to 64 GB. These are manufacturer specifications, not results from the site’s own testing.
The account also describes recurring kernel panics on the database Mac since August, at the worst roughly every five days. Meyer said an Aug. 8 crash caused 2¼ hours of database downtime. A NAS would not stop those failures, but a local copy might shorten restoration time. The site cites the US-CERT 3-2-1 backup principle—three copies, on two media types, with one offsite—as the rationale for combining local storage with cloud storage.
“That was the day I stopped treating a sync service as a backup.”

Setup and Safeguards Await Testing
The NAS was not yet on the network as of Nov. 1, and neither acceptance test had run. It remains unknown whether Time Machine will work as planned with a non-admin account or whether snapshots will be inaccessible to that account. RAID 6 capacity figures describe the intended layout; the device has not yet been configured to confirm usable capacity or recovery behavior.
The proposed schedule puts disk-heavy work between 20:00 and 06:00, with drives intended to sleep during the workday. Whether the system can follow that schedule without disrupting backups is also untested. Meyer says there will be no live database change log on spinning drives, no administrator credentials for AI agents, no internet-facing remote access, and no UGREEN cloud mirror treated as the offsite backup. These are stated design choices, not independently verified controls.
The article is not a review or long-term test. Meyer says he paid for the NAS, drives and SSD himself, that UGREEN did not supply or sponsor them, and that the company had not reviewed the article. The site says it has no affiliate links. It has not reported actual restore times, reliability results or whether the planned Backblaze B2 copy is operating.
Two Tests Before Rollout
The next milestone is connecting and configuring the NAS, then running the two acceptance tests: a Time Machine backup from a non-admin account and confirmation that snapshots remain beyond that account’s reach. Meyer says the NAS will be returned if either test fails. Until those checks are complete, the existing backup routine remains in place: local Time Machine disks on two Macs and an iCloud copy of the nightly database dump.
If the tests pass, the site’s plan is to deploy the RAID 6 storage for backups, use the SSD pool for containers and test databases, and add encrypted offsite copies in Backblaze B2. Meyer says he will report results once the system is running. No deployment date or results have been announced.
Key Questions
Has the UGREEN NAS been set up?
No. As of Nov. 1, 2026, the NAS had been delivered and fitted with four hard drives and an NVMe SSD, but it was not connected to the network or configured.
Why did ThorstenMeyerAI.com buy a NAS?
The site says 29 duplicate iCloud conflict copies nearly filled its database server, and a later cleanup job timed out. A local NAS is intended to provide a nearby backup copy and a separate place for test databases.
How much storage is planned?
The proposed four-drive RAID 6 setup is estimated at about 32 TB usable. Meyer says six 16 TB drives in the same arrangement would provide about 64 TB, though neither configuration has been tested in the NAS.
What must happen before the NAS is kept?
Two tests must pass: Time Machine must back up using a non-admin account, and snapshots must remain inaccessible to that account. Meyer says the NAS will be returned if either test fails.
Will the NAS replace offsite backups?
No. The plan pairs local storage with an encrypted offsite copy sent to Backblaze B2 using restic and Object Lock. That offsite setup has not yet been reported as running.
