TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after duplicate files from a synced backup nearly filled a database server. As of November 1, 2026, the NAS is equipped with four 16 TB drives and an NVMe SSD but is not installed or tested; its proposed backup and storage setup remains a plan.
ThorstenMeyerAI.com says it has bought a UGREEN NASync DXP6800 Pro after duplicate backup files in an iCloud folder left one of its servers with 2% free disk space. The six-bay network storage device has been delivered and equipped, but as of November 1, 2026, it is not connected to the network and its planned backup setup has not been tested.
The site’s account says two machines uploaded database dumps with the same file name to one iCloud folder on September 17. The resulting 29 conflict copies nearly filled the server that runs its main database. A later cleanup problem also emerged: on October 29, a nightly job timed out while trying to remove old dump copies from the iCloud folder. The publication says the dump itself was intact; managing the synced copies was the problem.
The hardware purchased comprises the six-bay DXP6800 Pro, four Seagate IronWolf Pro 16 TB hard drives and one NVMe SSD. The planned arrangement uses the four hard drives in RAID 6, which the publication estimates would provide about 32 TB of usable capacity and tolerate the failure of two drives. The SSD is intended for a separate pool for containers and test databases. These are planned capacities and uses, not results from an operating system.
The author says the NAS, drives and SSD were bought with personal funds and that UGREEN did not supply or sponsor them. The piece is not a review or long-term test. It reports UGREEN and Seagate product specifications separately from the publication’s own fleet measurements, and says the current backup routine remains in place until the new system passes its tests.

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 distinction between synchronization and backup. A sync service can reproduce deletions or unwanted copies across devices; it does not necessarily preserve a clean, separately recoverable version. The publication says UGREEN’s help center gives a similar warning for its Cloud Drives app: with two-way sync, a deletion on one side is reflected on the other.
A local NAS could provide a nearby destination for backups and shorten recovery compared with downloading hundreds of gigabytes over an office internet connection. That matters for this operation because its main database supports its publishing system, and the author reports recurring kernel panics on the database machine. The NAS cannot prevent those crashes, but a tested local copy could make restoration quicker.
The planned system also separates routine backups from test workloads. The publication says test databases currently run in Docker on a laptop, where one virtual disk had grown to about 30 GB. Moving that workload to a separate SSD pool could reduce demand on the laptop, although that benefit has not yet been measured.

The Storage Problem Behind the Purchase
The operation is described as a handful of Macs running a database, local AI models, content pipelines and tests, rather than a data center. In measurements taken on October 6, the main desk machine used about 2.6 TB, the database server about 744 GB, including a 293 GB database, and the model server about 3.2 TB, mostly model files that could be downloaded again. The publication estimates its present backup requirement at 6 to 8 TB.
The author says a database server crash on August 8 caused 2¼ hours of downtime, and that kernel panics had recurred since August, at their worst roughly every five days. Those incidents are the publication’s own account, not independently verified findings. The article also invokes the 3-2-1 backup rule—three copies, on two media types, with one offsite—while treating cloud storage as the offsite layer rather than the first landing place for every backup.
According to UGREEN’s specifications cited by the publication, the DXP6800 Pro has six SATA bays, two M.2 slots, a 10-core Intel Core i5-1235U processor, two 10GbE ports and 8 GB of DDR5 memory expandable to 64 GB. The author says the six drive bays, which leave room to add drives later, were the reason for choosing this model over a cheaper four-bay option. These specifications describe the product; they do not establish how it will perform in this particular setup.
“That was the day I stopped treating a sync service as a backup.”

Deployment and Safeguards Still Pending
The system has not yet joined the network, and the two stated acceptance tests have not run. The proposed RAID 6 layout, account permissions, snapshots, restore process and offsite copy are therefore plans rather than demonstrated protections. The publication says its existing backups still use local Time Machine disks on two Macs and an iCloud copy of the nightly database dump.
The intended design adds separate non-admin accounts and quotas for each Mac, daily snapshots those accounts cannot see or delete, and an encrypted offsite copy sent with restic to Backblaze B2 using Object Lock. The author says the system will not expose remote access to the internet, give AI agents administrator credentials, or rely on UGREEN’s cloud mirror as its offsite backup. It remains unclear whether the NAS can be configured and tested to meet those requirements, or how quickly the full fleet could be restored.
Acceptance Tests Before Rollout
The first step is to connect and configure the NAS, then run the two tests the author has set as gates: whether Time Machine works with a non-admin account, and whether snapshots remain inaccessible to that account. The publication says it will return the device if either test fails.
If the tests pass, the next stages are to implement the proposed storage pools, access controls, snapshot schedule and encrypted offsite copy, then check that backup and recovery work in practice. The author says disk-heavy work is planned for 20:00 to 06:00, with drives intended to sleep during the workday. No rollout date or measured performance results have been reported; Meyer says the publication will report back once the NAS is running.
Key Questions
What happened to the existing backup?
According to ThorstenMeyerAI.com, two machines placed database dumps with the same name in an iCloud folder. The resulting 29 conflict copies left the database server with 2% free disk space. The publication says its current backup routine is still running while the NAS remains unconfigured.
Is the DXP6800 Pro already backing up the Macs?
No. The NAS has been delivered and equipped, but as of November 1, 2026, it is not on the network. The planned setup and its acceptance tests have not run.
How much capacity does the planned drive layout provide?
The publication estimates that four 16 TB drives in RAID 6 would provide about 32 TB usable, with the array able to withstand two drive failures without data loss. That is a planned configuration and estimate, not a tested result.
What safeguards are planned?
The proposed design uses separate non-admin backup accounts and quotas, daily snapshots those accounts cannot delete, and an encrypted offsite copy to Backblaze B2 with Object Lock. The publication says those protections remain untested.
Why choose a six-bay model instead of a four-bay NAS?
Meyer says the extra bays offer room to add drives without replacing the existing ones. The publication describes that as the reason for choosing the DXP6800 Pro, but has not reported operating results or a comparison test.
