TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after duplicate files from an iCloud sync folder nearly filled its database server. As of Nov. 1, 2026, the NAS has four hard drives and an SSD installed but is not connected or configured; the backup plan and its acceptance tests remain unproven.
ThorstenMeyerAI.com has bought a six-bay UGREEN NASync DXP6800 Pro for its small AI and publishing operation after duplicate files in an iCloud sync folder left a database server with just 2% free disk space. The device has been equipped with four hard drives and an NVMe SSD, but as of Nov. 1 it is not connected to the network, and the site’s proposed backup system has not yet been tested.
The site’s account says that on Sept. 17, two machines uploaded database dumps with the same name to one iCloud folder. The resulting sync conflicts produced 29 copies and nearly filled the server. A separate backup-management problem surfaced on Oct. 29, when cleanup of old dump files timed out while iCloud was busy. The author says the incidents led him to stop treating a sync service as a backup.
The purchased system is fitted with four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. The planned arrangement puts the hard drives in RAID 6 for backups, with about 32 TB of usable capacity according to the article’s estimate, and uses the SSD as a separate pool for containers and test databases. These are planned settings, not a deployed configuration or measured result.
The article says the NAS was paid for by the author, with no manufacturer sample or sponsorship. It also says the piece is not a product review or long-term test. The company specifications cited for the model include six SATA bays, two M.2 slots, a 10-core Intel Core i5-1235U, two 10GbE ports and 8 GB of DDR5 memory expandable to 64 GB. The author says he chose six bays over a cheaper four-bay option to leave room for expansion.

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 addresses a specific operational weakness: the site’s existing copies relied partly on a sync service that reproduced conflicting files and complicated cleanup. A network-attached storage device could provide a local backup destination, which the author expects would allow faster restoration than downloading hundreds of gigabytes from cloud storage. That benefit has not yet been measured in this setup.
The planned approach also separates backup storage from files used for active work. The author says large disk operations would run from 20:00 to 06:00 so the drives can sleep during office hours. He plans separate accounts and quotas for each Mac, daily snapshots those accounts cannot manage, and an encrypted offsite copy using restic and Backblaze B2 with Object Lock. Those measures are a proposed design, not evidence that the NAS has passed recovery or security tests.
The case may interest small teams running databases, local AI models and content pipelines without dedicated data-center infrastructure. The article’s figures put current backup needs at about 6 to 8 TB, rather than at the full size of every machine’s storage. The central question is whether the extra hardware and administration provide a dependable recovery route, not simply more disk space.

The Storage Failures Behind the Purchase
The operation described in the article uses several Macs: one runs its main Postgres database, another hosts local AI models, and others handle publishing workflows and tests. Measurements taken on Oct. 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 about 293 GB; the author says many model files can be downloaded again.
The database server had also experienced recurring kernel panics since August, according to the author. A crash on Aug. 8 caused 2¼ hours of database downtime. The article stresses that a NAS cannot prevent a computer failure; its proposed role is to make restoration quicker. The author also says test databases had grown to about 30 GB in a virtual disk on his laptop, adding storage use and fan noise.
The article cites the familiar 3-2-1 backup rule: keep three copies of important files, on two types of media, with one copy offsite. Its planned NAS would supply an on-site copy, while the proposed Backblaze B2 copy would remain offsite. The current arrangement, however, remains local Time Machine disks on two Macs and an iCloud copy of the nightly database dump.
“That was the day I stopped treating a sync service as a backup.”

Deployment and Restore Tests Pending
The NAS has not been put on the network, and the article reports no completed configuration, backup run or restoration test. Its planned RAID 6 capacity, account permissions, snapshot protections and offsite copy have not been validated in practice. The two stated acceptance tests are whether Time Machine works with a non-admin account and whether snapshots remain inaccessible to that account.
It is also unknown whether the proposed schedule will let the disks sleep during working hours, how quickly the NAS will restore the site’s database, or whether the system will prevent the kinds of duplicate-file and cleanup problems described. The author says the NAS will be returned if either acceptance test fails. Until testing is reported, the hardware purchase is confirmed but the proposed benefits remain expectations.
Two Tests Before Keeping the NAS
The next milestone is connecting and configuring the NAS, then testing Time Machine with a non-admin account and confirming that daily snapshots cannot be accessed or deleted by that account. The author says both tests must pass for the NAS to stay. If either fails, the plan is to return the hardware.
After rollout, the site says it will report actual results. Those would show whether the device can provide the intended local backup and restore path, and whether the separate encrypted offsite copy works as planned. Until then, existing backups continue on the two Macs and through the nightly database dump copied to iCloud.
Key Questions
Is the UGREEN NAS already backing up the site’s computers?
No. As of Nov. 1, 2026, the NAS had been delivered and fitted with drives and an SSD, but was not on the network or configured. The existing backup routine remains in place.
Why did the publisher buy a six-bay model?
The author says he chose the DXP6800 Pro over a cheaper four-bay option to leave room to add drives later. He describes six bays as the main reason for the purchase choice.
What storage setup is planned?
The plan is to use four 16 TB hard drives in RAID 6 for backups, estimated by the article at about 32 TB usable, and a separate NVMe SSD pool for containers and test databases. This configuration has not been tested.
What caused the original storage problem?
According to the author, two machines uploaded database dumps with the same file name to an iCloud folder. Sync conflicts created 29 duplicate copies, leaving the database server with 2% free disk space.
What must happen before the author keeps the NAS?
The device must pass two acceptance tests: Time Machine must work using a non-admin account, and snapshots must remain out of that account’s reach. The author says the NAS will be returned if either test fails.
