TL;DR
ThorstenMeyerAI.com has bought a UGREEN NASync DXP6800 Pro after duplicate cloud-sync files nearly filled a database server. As of November 1, 2026, the NAS has four hard drives and an NVMe SSD installed but is not connected or configured; its planned backup setup has not been tested.
ThorstenMeyerAI.com has bought a six-bay UGREEN NASync DXP6800 Pro after a cloud-sync conflict left one of its servers with only 2% free disk space. The NAS has been fitted with four 16 TB hard drives and an NVMe SSD, but it is not yet connected to the network or configured, so the backup plan has not been tested.
The purchase followed an incident on September 17, when two machines uploaded database dumps with the same name to an iCloud folder. The site’s account says iCloud retained conflict copies, producing 29 duplicate files and leaving the server running its main database nearly full. On October 29, a nightly backup job also reported an error after cleanup of old copies timed out while iCloud was busy.
Thorsten Meyer says the operation’s current backup needs are about 6 to 8 TB. Measurements taken 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. The site says most of the model files can be downloaded again, while the database and working files require protection.
The purchased system is equipped with four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. Meyer’s planned configuration is RAID 6 for the hard drives, which he estimates would provide about 32 TB of usable capacity, with the SSD in a separate pool for containers and test databases. Those capacities and the proposed arrangement are not yet validated in operation.

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 reported incidents point to two distinct risks: sync can reproduce mistakes, and a backup that is slow or difficult to manage may not provide a practical recovery path. A local NAS could give the operation another copy on its own network, potentially making large restores faster than retrieving them from cloud storage. That benefit remains a plan, not a measured result: the device has not been set up and no restore test has been run.
The project also reflects a particular operational trade-off. The site is not describing an enterprise data center, but a small group of Macs running a database, local AI models, content workflows, and tests. A storage system with spare bays could add capacity without replacing all drives, while moving test databases off a work laptop could reduce local storage use. Whether the added hardware and administration are worthwhile will depend on the rollout and tests.
Meyer’s proposed safeguards include separate, non-admin accounts for each Mac, storage quotas, snapshots that those accounts cannot delete, and an encrypted offsite copy using restic to Backblaze B2 with Object Lock. The plan is intended to keep a local failure, accidental deletion, or compromised account from removing every copy. None of those protections has been confirmed on the new NAS yet.

How the Backup Plan Changed
Meyer says the server running the main database has also experienced recurring kernel panics since August, at its worst about every five days. A crash on August 8 caused 2¼ hours of database downtime, according to the site. A NAS would not prevent those crashes, but a nearby copy could shorten recovery if a restore works as intended.
The site says it had relied on local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. Meyer’s account argues that a sync service should not be treated as a complete backup: files deleted or changed on one side may also be removed or changed on the other. UGREEN’s help center similarly states that its Cloud Drives app’s two-way sync propagates deletions between sides.
Meyer says he chose the six-bay DXP6800 Pro over a cheaper four-bay model because of room for future expansion. According to UGREEN’s specifications, the system has 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. These are manufacturer specifications; the article is not a product review or long-term test. Meyer says he paid for the NAS and drives himself, and that UGREEN did not provide or sponsor the equipment.
“That was the day I stopped treating a sync service as a backup.”

Installation and Tests Still Pending
As of November 1, 2026, the NAS has been delivered and fitted with drives, but it is not on the network and has not been configured. The proposed RAID 6 arrangement, account permissions, quotas, snapshots, and offsite copy are therefore planned rather than demonstrated. The two stated acceptance tests have not run.
It is also not yet clear how long restores will take, whether the setup will handle the Macs’ backup workflows reliably, or whether the hard drives will sleep during working hours as Meyer intends. The site has not reported actual noise, performance, or reliability results. Its stated storage figures describe current measurements, not a projection of future needs or a tested capacity outcome.
The existing backup routine remains in place for now: local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. The account does not provide a confirmed date for network installation or say whether the NAS will pass either test.
Two Gates Before Deployment
Meyer says the system must first pass two acceptance tests: backing up with Time Machine through a non-admin account, and confirming that snapshots remain inaccessible to that account. If either test fails, he says he will return the NAS. Until those checks are complete, the new unit should not be treated as an active backup or as protection against another server outage.
If the tests pass, the planned next steps are to configure the hard drives as a RAID 6 pool for backups, use the NVMe SSD separately for containers and test databases, and schedule disk-heavy tasks overnight, from 20:00 to 06:00. The longer-term plan adds an encrypted restic copy to Backblaze B2 with Object Lock. Meyer says he intends to report real-world results after the system is running; no rollout date or test results have been published.
Key Questions
Is the UGREEN NAS already backing up the site’s computers?
No. As of November 1, 2026, it has not been connected to the network or configured. The site says its existing Time Machine and iCloud backups remain in use.
Why did ThorstenMeyerAI.com buy a NAS?
The site says duplicate iCloud conflict copies nearly filled its database server, while cleanup of old files later timed out. It wants a local storage destination for backups and a separate place for test databases.
How much storage is planned?
The proposed setup uses four 16 TB drives in RAID 6, which Meyer estimates would provide about 32 TB usable. This is a planned configuration, not a tested result.
What must happen before the NAS is put into service?
It must pass a Time Machine test using a non-admin account and a snapshot test showing that the account cannot access or delete snapshots. Meyer says the NAS will be returned if either test fails.
Does the NAS replace the offsite backup?
No. Meyer’s plan treats the NAS as a local copy and proposes a separate encrypted offsite copy to Backblaze B2 using restic and Object Lock. That offsite setup has not yet been implemented.
