TL;DR
Thorsten Meyer says his publishing operation bought a UGREEN NASync DXP6800 Pro after iCloud conflict copies nearly filled a database server. As of November 1, 2026, the NAS has been equipped but is not connected or configured; the proposed backup design and its two acceptance tests remain unverified.
Thorsten Meyer says he has bought a UGREEN NASync DXP6800 Pro after duplicated iCloud backup files left one of his servers with 2% free disk space. The NAS has been delivered and fitted with drives, but as of November 1 it is not connected to the network or configured, so the proposed backup system and its safeguards have not been tested.
Meyer, writing on ThorstenMeyerAI.com, says the incident happened on September 17, when two machines sent database dumps with the same filename to one iCloud folder. He reports that the service produced 29 conflict copies, nearly filling the server that runs his main database. A separate backup cleanup job also encountered a timeout on October 29 while trying to remove old copies. Meyer says the backup itself was intact, but managing the copies had stalled.
The purchased system is equipped with four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. The plan is to put the hard drives in RAID 6, which Meyer estimates would provide about 32 TB usable capacity and tolerate the failure of two drives without data loss. The SSD would be a separate pool for containers and test databases. Those figures describe the proposed arrangement, not a completed or tested configuration.
Meyer says the setup must pass two tests before he keeps the NAS: Time Machine backups using a non-admin account and snapshots that the backup accounts cannot access or delete. If either test fails, he says he will return the unit. Until rollout, backups remain on local Time Machine disks for two Macs and an iCloud copy of the nightly database dump.

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 Could Speed Recovery
The purchase is aimed at reducing the consequences of backup-copy failures and making large restores faster. Meyer says his operation currently needs about 6 to 8 TB of backup capacity. A local NAS could provide another copy on the office network, rather than making cloud storage the first destination for every backup. It could also give the team a place for test databases that currently run in a virtual disk on a laptop.
The plan separates several safeguards: individual Mac backup accounts with quotas, daily snapshots that those accounts cannot manage, and an encrypted offsite copy sent with restic to Backblaze B2 with Object Lock. These are intended protections, not proven results. A NAS does not prevent the reported kernel panics on the database Mac, and it cannot by itself guarantee recoverability; the proposed tests and later restore experience will show whether the design works in practice.
Meyer also says disk-heavy tasks would run from 8 p.m. to 6 a.m. so the drives can sleep during the workday. The intended trade-off is local capacity and faster access against the cost, noise and upkeep of a multi-drive system. For now, those operational benefits are expectations rather than measured outcomes.

From iCloud Conflicts to Six Bays
Meyer describes a small fleet of Macs: one runs the main Postgres database, another serves local AI models, and others handle publishing workflows and tests. His measurements from 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. He says the database itself was about 293 GB and much of the model storage could be downloaded again.
He chose the six-bay DXP6800 Pro over a cheaper four-bay model because he wants room to add drives without replacing the existing ones. According to specifications Meyer attributes to UGREEN, the device has six SATA bays, two M.2 slots, two 10GbE ports and an Intel Core i5-1235U processor; its 8 GB of DDR5 memory can be expanded to 64 GB. Those are manufacturer specifications, not independent performance findings. Meyer says he paid for the NAS and its drives himself, received no sample or sponsorship, and includes no affiliate links. He describes the article as a setup plan, not a review or long-term test.
“That was the day I stopped treating a sync service as a backup.”

The Backup Plan Has Not Been Tested
The NAS is not yet on the network, and Meyer says neither acceptance test has been run. It is not yet known whether Time Machine will work reliably with the planned non-admin account, whether snapshots will remain inaccessible to that account, or how long restores will take. The RAID 6 capacity estimate is also a plan; usable space can vary with formatting and system overhead.
Meyer has not reported real-world noise, power use, transfer speeds, or long-term reliability. The intended offsite copy and Object Lock settings have not been put into operation, either. He says he will publish results once the system is running, but does not give a rollout date.
Acceptance Tests Before Rollout
The next step is to connect and configure the NAS, then run the two stated tests: a Time Machine backup under a non-admin account and a check that snapshots remain beyond that account’s reach. Meyer says the system will be returned if either test fails. If it passes, the planned rollout adds scheduled local backups, snapshots and an encrypted offsite copy; no completion date or test results have been announced.
Until then, the operation continues using its existing local Time Machine disks and iCloud database-dump copy. Meyer says he intends to report back with results from actual use, which should clarify whether the local system improves recovery without introducing problems of its own.
Key Questions
Has the UGREEN NAS been set up and tested?
No. Meyer says it has been delivered and equipped with drives, but it is not connected to the network or configured as of November 1, 2026. The two acceptance tests have not run.
Why did Meyer buy a NAS?
He says 29 iCloud conflict copies of database dumps left a server with 2% free space. A local NAS is intended to provide another backup destination and make large restores faster than relying on a cloud download alone.
What storage arrangement is planned?
The proposal is four 16 TB hard drives in RAID 6, estimated by Meyer at about 32 TB usable, plus a separate NVMe SSD pool for containers and test databases. This configuration has not yet been tested.
What must happen before Meyer keeps the NAS?
He says it must pass a Time Machine test with a non-admin account and a test showing that account cannot access or delete snapshots. If either fails, he says he will return the unit.
