TL;DR
ThorstenMeyerAI.com says repeated iCloud backup conflicts nearly filled a database server, prompting the purchase of a six-bay UGREEN NASync DXP6800 Pro. The NAS has been delivered but is not installed; its planned backup setup has not passed acceptance tests, and the operation’s existing backups remain in place for now.
ThorstenMeyerAI.com, a small AI and publishing operation, has bought a UGREEN NASync DXP6800 Pro after duplicate cloud-sync files nearly filled the server holding its main database. As of November 1, 2026, the six-bay device has been delivered and equipped but is not connected to the network, so its proposed backup system has not yet been tested.
The purchase followed a September 17 incident in which a server fell to 2% free disk space after two machines uploaded database dumps with the same filename to an iCloud folder. The site’s account says iCloud retained repeated conflict copies, leaving 29 duplicates. A separate backup-management problem surfaced on October 29, when a cleanup job timed out while trying to delete old copies from the folder.
The operator says the NAS cost was paid personally, and that UGREEN did not provide or sponsor the device. The unit is fitted with four Seagate IronWolf Pro 16 TB hard drives and one NVMe SSD. The planned arrangement puts the hard drives in RAID 6 for backups, with the SSD in a separate pool for containers and test databases. The site estimates the four-drive setup would provide about 32 TB of usable capacity; filling all six bays with 16 TB drives could provide about 64 TB under the same RAID arrangement.
Those figures describe the planned configuration, not a tested result. The site says its current backups still use local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. It plans to accept the NAS only if two checks succeed: Time Machine must work through a non-admin account, and snapshots must remain inaccessible to that account. The operator says the device will be returned if either test fails.

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 Backup Capacity Matters
The decision addresses a specific weakness in the operation’s backup process: syncing files is not the same as preserving recoverable versions. In the reported incident, the service copied conflicting files repeatedly, while a later cleanup timed out. The near-full disk mattered because the server runs the operation’s main database, and a full disk can interrupt database work.
A local NAS could provide a nearby copy for faster restoration than retrieving hundreds of gigabytes over an internet connection, while keeping storage separate from the Macs being backed up. The operator says the fleet’s measured storage includes about 2.6 TB on the main desk machine, 744 GB on the database server, and 3.2 TB on the model server; the stated present backup requirement is about 6 to 8 TB. These are the site’s measurements, not independently verified figures.
The proposed safeguards also reflect the risk of giving automated systems broad access to backups. The plan calls for separate, non-admin accounts and quotas for each Mac, daily snapshots those accounts cannot delete, and an encrypted offsite copy using restic to Backblaze B2 with Object Lock. The author says AI agents will not receive administrator credentials and that the NAS will not be exposed through remote internet access. These measures remain a plan until configured and tested.

From Sync Errors to NAS Purchase
The operation runs several Macs around the clock: one holds its main Postgres database, another serves local AI models, and others handle publishing workflows and tests. The author says the model files make up much of the model server’s storage and can be downloaded again, while database and publishing data are the more immediate backup concern.
The site also describes recurring kernel panics on the database Mac since August, at their worst occurring roughly every five days. It reports that an August 8 crash caused 2 hours and 15 minutes of database downtime. A NAS would not prevent that kind of hardware or system failure, but the author expects a local restore to be faster than a cloud download. Separately, test databases running in Docker had grown to about 30 GB on the author’s laptop.
The DXP6800 Pro was chosen over a less expensive four-bay model because the operator wanted room to add drives without replacing existing ones. UGREEN’s product specifications, as cited by the source, list six SATA bays, two M.2 slots, a 10-core Intel Core i5-1235U, dual 10GbE ports, and 8 GB of DDR5 memory expandable to 64 GB. Those are manufacturer specifications; the article is not a review or long-term test.
“That was the day I stopped treating a sync service as a backup.”

Installation and Safeguards Remain Untested
The NAS is not yet on the network, and neither acceptance test has run. Its actual transfer speeds, snapshot behavior, compatibility with the operation’s Time Machine setup, noise levels, reliability, and restore times are not established by the source. The stated capacity is a planned estimate, not a measurement from an operating system.
It is also unclear when installation will begin or whether the proposed encrypted offsite copy and Object Lock configuration will be completed as described. The author says the article is not a review or long-term test and promises to report results after the system is running. Until then, the existing local disks and iCloud copy remain the operation’s backup arrangement.
Two Tests Before the Rollout
The next step is to connect and configure the NAS, then test Time Machine using a non-admin account and verify that the account cannot access or delete snapshots. The author says failure of either test will mean returning the device. If both pass, the planned rollout would add the NAS as local backup storage, with disk-heavy work scheduled from 8 p.m. to 6 a.m. so the drives can sleep during the workday.
The operator says a later report will cover real-world results once the NAS is in use. That update would clarify whether the planned storage layout, access controls, snapshots, and offsite copy work as intended; no deployment date or performance results have been provided.
Key Questions
Why did ThorstenMeyerAI.com buy the UGREEN NAS?
The site says repeated iCloud conflict copies nearly filled its database server, and a later cleanup job timed out. It wants a local backup destination that can also support faster restores than downloading large amounts of data from cloud storage.
Is the DXP6800 Pro already backing up the Macs?
No. As of November 1, 2026, the NAS had been delivered and equipped but was not on the network. The operation says it is still using its existing Time Machine disks and iCloud database-dump copy.
How much storage is planned?
The proposed setup uses four 16 TB hard drives in RAID 6, which the site estimates will yield about 32 TB usable. The site estimates about 64 TB if all six bays are eventually filled with 16 TB drives in the same arrangement.
What has to happen before the NAS is accepted?
The operator plans to test Time Machine with a non-admin account and check that the account cannot reach or delete snapshots. Meyer says the NAS will be returned if either test fails.
Does the article establish that this NAS improves backup reliability?
No. The device has not been installed or tested, so its reliability and restore performance are not yet established. The article describes the purchase rationale and intended design, rather than reporting results from a completed deployment.
