TL;DR
Thorsten Meyer says he bought a UGREEN NASync DXP6800 Pro after duplicate iCloud backup files nearly filled a database server. The NAS has been delivered with four hard drives and an NVMe SSD, but is not yet connected or configured; its planned backup setup must pass two tests before it is kept.
Thorsten Meyer says he has bought a UGREEN NASync DXP6800 Pro after a backup-sync error left a database server with just 2% free disk space. The six-bay NAS has arrived with four hard drives and an NVMe SSD, but it is not connected to the network or configured, so the proposed backup system remains a plan rather than a tested solution.
Meyer, writing on ThorstenMeyerAI.com on November 1, traced the September 17 incident to two machines sending database dumps with the same filename to an iCloud folder. The service generated 29 conflict copies, according to his account, bringing the server close to full. A separate backup-cleanup job timed out on October 29 while iCloud was busy. Meyer says the backup data itself was intact in that instance, but managing old copies had failed.
The purchased hardware comprises the DXP6800 Pro, four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. Meyer’s planned arrangement is to put the four hard drives in RAID 6, which he estimates would provide about 32 TB of usable capacity, and use the SSD as a separate pool for containers and test databases. UGREEN’s listed specifications, as reported in the article, 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 proposed safeguards include separate, non-administrator accounts and storage quotas for each Mac, daily snapshots those accounts cannot access or delete, and an encrypted offsite copy sent with restic to Backblaze B2 with Object Lock. Meyer says the plan excludes internet-accessible remote access, administrator credentials for AI agents and reliance on a UGREEN cloud mirror as the offsite backup. None of these measures has been tested on the new NAS yet.

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 practical weakness in the operation’s existing backup route: a synced copy can reproduce unwanted changes, while a cloud restore of hundreds of gigabytes can take hours over a home-office connection. A local NAS could provide a separate on-site copy and a faster path to restoration after a machine failure, but that benefit depends on the setup working as intended.
Meyer says the small publishing and AI operation currently needs about 6 to 8 TB of backup capacity. His October 6 measurements put the main desk machine at about 2.6 TB, the database server at 744 GB, and the model server at 3.2 TB, much of it replaceable model files. The choice of six bays over a cheaper four-bay model reflects his stated preference for room to add drives later without replacing the existing set. That is a rationale for this purchase, not evidence that the system has improved recovery times.

How Sync Errors Led to the Purchase
Meyer describes a fleet of Macs running a publishing database, local AI models, content pipelines and tests. Before the purchase, backups relied on local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. As of November 1, that old process is still running; the NAS has not taken over any backup job.
The article also describes recurring kernel panics on the database Mac since August. Meyer says the crashes occurred roughly every five days at their worst, and one on August 8 caused 2¼ hours of database downtime. He notes that a NAS cannot prevent a computer crash, though a nearby copy might shorten recovery. He presents the account as a setup report, not a product review or long-term test, and says he paid for the equipment himself. He states that UGREEN did not provide a sample or sponsor the article and that it contains no affiliate links.
“That was the day I stopped treating a sync service as a backup.”

Setup Tests Have Not Run
The main unanswered question is whether the NAS can meet the operation’s requirements in practice. Meyer says the Time Machine test using a non-admin account and the test of snapshots that the account cannot access or delete have not run. Until they do, it is not known whether the intended account permissions, backup workflow or recovery process will work as planned.
Actual usable capacity, network performance, noise levels, drive-sleep behavior and restore times are also unreported. The stated 32 TB figure is an estimate for the planned four-drive RAID 6 arrangement, not a measured result. Meyer says disk-heavy work is intended to run from 20:00 to 06:00 so the drives can sleep during working hours, but that schedule has not been implemented. The article provides no evidence yet that the NAS has reduced downtime or prevented backup errors.
Time Machine and Snapshot Checks
Meyer says the next step is to connect and configure the NAS, then run the two acceptance tests: a Time Machine backup through a non-administrator account and a check that daily snapshots remain inaccessible and undeletable from that account. He has said the NAS will be returned if either test fails. If they pass, the wider plan is to add the encrypted offsite copy and schedule disk-heavy tasks overnight.
For now, the Macs continue to use local Time Machine disks and the iCloud database-dump copy. Meyer says he intends to report back with results once the NAS is running, so its performance and the success of the proposed backup layers remain to be established.
Key Questions
Has the UGREEN NAS been set up?
No. Meyer says it has been delivered and equipped with four hard drives and an NVMe SSD, but it is not yet connected to the network or configured.
Why did Meyer buy the six-bay model?
He says the extra bays provide room to expand without replacing the current drives. He chose it over a cheaper four-bay model, although the planned system has not yet been tested.
What storage setup is planned?
The plan is to use four 16 TB hard drives in RAID 6, estimated at about 32 TB usable, and keep the NVMe SSD in a separate pool for containers and test databases. These are planned figures and uses, not verified results.
What must pass before Meyer keeps the NAS?
He says it must pass a Time Machine backup test with a non-admin account and a test confirming that account cannot access or delete snapshots. He says the device will be returned if either test fails.
Are the old backups still in place?
Yes. As of November 1, Meyer says backups still run to local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. The NAS has not replaced those arrangements.
