TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after duplicate files from an iCloud sync workflow nearly filled a database server. The six-bay NAS has been delivered with four 16 TB hard drives and an NVMe SSD, but it is not yet connected or tested; the planned backup setup remains unverified.
ThorstenMeyerAI.com has bought UGREEN’s six-bay NASync DXP6800 Pro for a planned local backup system and AI testing environment, after duplicate files in an iCloud sync folder nearly filled a server; see this guide to UGREEN NAS and AI alternatives for related context. As of November 1, 2026, the NAS has been delivered with four hard drives and an NVMe SSD, but has not been connected to the network or tested, so the proposed setup is not yet operating.
The site’s account says that on September 17, two machines uploaded database dumps with the same filename to one iCloud folder. The resulting 29 conflict copies left the database server with 2% free disk space. A separate backup-cleanup job later timed out while attempting to remove old copies from the folder. The publisher says it bought local network storage because a sync service can replicate unwanted changes as well as useful files.
The purchased unit is equipped with four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. The planned arrangement is RAID 6 for the hard drives, which the publisher estimates would provide about 32 TB of usable capacity, with the SSD in a separate pool for containers and test databases. Those are intended specifications and estimates, not results from a completed installation.
The article describes a staged backup plan: separate, quota-limited accounts for the two Macs; daily snapshots that those accounts cannot access or delete; and an encrypted offsite copy using restic and Backblaze B2 Object Lock. The author says the NAS was paid for personally, with no manufacturer sample, sponsorship or affiliate links. The piece is a purchase and setup plan, not a product review or long-term test.

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 Copies Matter Here
The purchase addresses a specific operational risk for a small publishing and AI operation: syncing files is not the same as keeping protected backup copies. In this case, conflict files consumed server space, while cleanup failed during a later run. A local NAS could offer a nearby restore source for large files, reducing reliance on cloud downloads over the publisher’s office connection.
The proposed design also separates routine Mac backups from test workloads. The author says the current measured storage needs are about 6 to 8 TB for backups, while model files account for much of the AI server’s storage and can be downloaded again. Six bays provide room to add drives later, but the extra capacity and faster recovery are potential benefits only; they have not been demonstrated in this deployment.
The safeguards matter as much as the hardware. Snapshots, restricted accounts and a separately stored offsite copy are intended to reduce the chance that a mistaken deletion, compromised account or local failure removes every copy. Whether the setup achieves that depends on successful configuration and testing.

From iCloud Conflicts to NAS
The publisher describes a fleet of several Macs: one runs its main PostgreSQL database, another hosts local AI models, and others handle content pipelines and tests. Measurements taken on 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. The database itself was reported at about 293 GB.
The article also says the database Mac has experienced recurring kernel panics since August. A crash on August 8 caused about 2¼ hours of database downtime, according to the publisher. A NAS would not prevent a computer crash, but a local copy might help restore data more quickly than retrieving large amounts from cloud storage.
UGREEN’s listed product features include six SATA bays, two M.2 slots, two 10GbE ports and an Intel Core i5-1235U processor. The publisher says its choice over a cheaper four-bay model was mainly about having room to expand without replacing existing drives. It also cites U.S. government guidance on the 3-2-1 backup approach: three copies, on two types of media, with one stored offsite.
“A sync service is not a backup.”

Setup and Safeguards Still Unproven
The NAS has not been configured, and the two acceptance tests have not been run. It is not yet known whether Time Machine will work as planned with the restricted account, whether snapshots will remain inaccessible to that account, or whether the full backup and restore workflow will be reliable.
The RAID 6 capacity figures are planning estimates, not a report of usable space after formatting or testing. The article also does not provide measured restore speeds, noise levels, power use, or long-term reliability results. The publisher says it will not place live database change logs on spinning drives, give AI agents administrator credentials, allow direct internet access, or rely on a UGREEN cloud mirror as its offsite copy.
Acceptance Tests Before Rollout
The next step is connecting the NAS and running the two stated acceptance tests. The publisher says the device will be returned if either the non-admin Time Machine backup or the protected-snapshot test fails. If both pass, the planned rollout is to use the hard-drive pool for backups and the SSD pool for containers and test databases, with disk-heavy tasks scheduled overnight.
ThorstenMeyerAI.com says it will report back with results once the system is running. Until then, the confirmed development is the purchase and the intended design—not a completed migration, a verified backup system or a tested performance claim.
Key Questions
What is the UGREEN NASync DXP6800 Pro being used for?
The publisher plans to use it for local backups of two Macs and to run containers and test databases on a separate NVMe SSD pool. The setup has not yet been installed.
Why did the publisher choose a six-bay model?
Thorsten Meyer says the additional bays provide room to expand storage without replacing drives. The planned initial setup uses four 16 TB hard drives in RAID 6.
Is the NAS already backing up the Macs?
No. As of November 1, 2026, the NAS had been delivered but was not on the network or configured. Existing backups were still using local Time Machine disks and an iCloud copy of the nightly database dump.
What tests must the NAS pass?
The publisher plans to test Time Machine with a non-admin account and confirm that the account cannot access or delete snapshots. The author says the NAS will be returned if either test fails.
Does this report establish the NAS’s performance or reliability?
No. The article is a purchase and setup plan, not a review or long-term test. Restore speed, noise, reliability and the final usable capacity have not been reported.
