TL;DR
ThorstenMeyerAI.com has bought a UGREEN NASync DXP6800 Pro after iCloud conflict copies nearly filled a database server and backup cleanup later timed out. The NAS has been equipped with four 16 TB drives and an NVMe SSD, but as of November 1 it is not connected or configured; the proposed backup setup and its acceptance tests remain unproven.
ThorstenMeyerAI.com has bought a UGREEN NASync DXP6800 Pro after duplicate iCloud backup files pushed one server to 2% free disk space, but the network storage device has not yet been installed or tested. As of November 1, the site says the purchase is complete and the NAS is equipped with four hard drives and an SSD; its proposed backup system remains a plan, not a verified result.
The purchase followed a September 17 incident in which 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 duplicate files and the database server nearly full. A separate backup-management problem surfaced on October 29, when a nightly job timed out while trying to delete old dump copies. The site says the database dump itself was intact, but the cleanup process failed.
The hardware has been fitted with four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. The planned arrangement uses the hard drives in RAID 6 for backups and a separate SSD pool for containers and test databases. According to the site, four drives in that configuration would provide about 32 TB of usable capacity; filling all six bays with 16 TB drives would raise that estimate to about 64 TB. Those figures describe the intended configuration, not a live system measurement.
The site says its present backup routine has not changed: two Macs use local Time Machine disks, and a nightly database dump is copied to iCloud. The NAS is not yet on the network, and neither of the two planned acceptance tests has run. The site says it will return the hardware if Time Machine cannot work with a non-admin account or if the planned snapshots are not protected from that account.

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 incident illustrates a difference between file synchronization and backup recovery. A sync service can copy changes across devices, but that may also replicate duplicates or deletions. In its account, ThorstenMeyerAI.com says the iCloud conflict copies consumed server space and that managing them later disrupted the cleanup job. The proposed NAS would give the operation a local destination for backups, rather than relying on a cloud folder as the first landing point.
A local copy could also make recovery from a large failure quicker than downloading hundreds of gigabytes over a home-office connection. That is a potential benefit, not one demonstrated by this purchase: the NAS has not been set up, and no restore-time results are available. The plan also retains an offsite copy, reflecting the site’s aim to combine nearby recovery with protection against a local incident.
The choice matters to small AI and publishing operations that store databases, model files and test environments across several computers. The site measured its current backup need at about 6 to 8 TB, while some AI model files can be downloaded again. It says the immediate issue was not simply total storage volume, but the reliability and management of the backup path.

From iCloud Conflicts to Six Bays
The operation runs several Macs around the clock: one holds the main publishing database, another serves local AI models, and others handle content pipelines and tests. 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 database itself accounted for about 293 GB of the server’s storage.
The site also reports recurring kernel panics on the database Mac since August, at their worst roughly every five days. It says an August 8 crash caused 2¼ hours of database downtime. A NAS would not prevent a computer crash, but the site’s stated aim is to shorten recovery by keeping a backup on the local network. Test databases have also taken space on the author’s laptop, including a Docker virtual disk that grew to about 30 GB.
The site chose the six-bay DXP6800 Pro over a less expensive four-bay model because it wanted room to add drives without replacing the existing ones. UGREEN’s product specifications, as cited by the site, list a 10-core Intel Core i5-1235U, two 10GbE ports, two M.2 slots and 8 GB of DDR5 memory expandable to 64 GB. These are manufacturer specifications, not independently tested performance figures.
“That was the day I stopped treating a sync service as a backup.”

The NAS Has Yet to Be Tested
The central uncertainty is whether the proposed system will work as intended. As of November 1, 2026, the NAS was not connected to the network or configured, and the two acceptance tests had not been run. The planned RAID arrangement, snapshot protections, account permissions and offsite backup process have not been demonstrated in operation.
The site proposes using restic to send an encrypted copy to Backblaze B2 with Object Lock, but has not reported a completed test of that process. It also plans to schedule disk-heavy work overnight and keep AI agents away from administrator credentials. These are stated design choices, not confirmed safeguards in a deployed system. UGREEN’s specifications and the site’s storage measurements likewise do not establish real-world speed, reliability or recovery time.
Two Tests Before Deployment
The next step is to connect and configure the NAS, then run the stated acceptance tests: confirm that Time Machine backups work through a non-admin account, and verify that snapshots remain unavailable for that account to view or delete. The site says it will return the unit if either test fails. Until those checks pass, the existing backups on local Time Machine disks and the iCloud database-dump copy remain in use.
After rollout, ThorstenMeyerAI.com says it plans to report real operating results. Those could establish whether the local NAS speeds up recovery, whether the account and snapshot controls work as designed, and whether the encrypted offsite copy provides an additional usable layer. No deployment date or test results have been published in the supplied account.
Key Questions
What happened to prompt the NAS purchase?
The site says repeated iCloud conflict copies from database dumps left a server at 2% free space on September 17. A later timeout while deleting old copies added to concerns about the existing backup process.
Is the UGREEN NAS operating yet?
No. As of November 1, 2026, it had been delivered and equipped with four 16 TB hard drives and an NVMe SSD, but was not connected or configured.
How will the drives be arranged?
The planned setup puts four 16 TB drives in RAID 6 for backups, with the NVMe SSD as a separate pool for containers and test databases. The site estimates about 32 TB usable from the four-drive arrangement; this has not been tested.
What tests must the NAS pass?
The site plans to test Time Machine using a non-admin account and confirm that the account cannot access or delete snapshots. It says the NAS will be returned if either test fails.
Will the NAS replace the offsite backup?
No. The plan is to keep an encrypted offsite copy using restic and Backblaze B2 with Object Lock. That part of the setup has not yet been deployed or verified.
