TL;DR
ThorstenMeyerAI.com says it has bought a UGREEN NASync DXP6800 Pro after duplicate iCloud backup 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 yet connected or configured; the planned backup system and its two acceptance tests remain unproven.
ThorstenMeyerAI.com has bought a UGREEN NASync DXP6800 Pro to serve as local backup and storage for its small AI and publishing operation, after duplicate files in an iCloud folder left a database server with just 2% free disk space. The NAS has been fitted with four hard drives and an NVMe SSD, but it is not yet on the network, so the proposed backup plan has not been tested.
The site’s operator, Thorsten Meyer, said the incident happened on September 17, when two machines uploaded database dumps with the same filename to a shared iCloud folder. The service generated 29 conflict copies, nearly filling the server that runs the site’s main database. Meyer said another backup-management problem emerged on October 29, when a nightly job timed out while trying to delete old copies from the busy iCloud folder.
The operation runs several Macs, including a database server, a machine for local AI models, and computers used for content pipelines and tests. Meyer measured the main desk machine at about 2.6 TB, the database server at about 744 GB and the model server at about 3.2 TB on October 6. He estimates its current backup requirement at 6 to 8 TB.
The planned NAS layout uses four Seagate IronWolf Pro 16 TB drives in RAID 6, which Meyer estimates would provide about 32 TB of usable capacity. He plans to use the NVMe SSD as a separate storage pool for containers and test databases. The hardware choice reflects a desire to retain room for expansion: the six-bay model has two more drive bays than the less expensive four-bay alternative Meyer considered.

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 backup process: cloud synchronization can reproduce mistakes, while restoring large datasets from an offsite service may take hours over a home-office connection. A local NAS could provide a faster recovery source and move test databases off Meyer’s laptop, if it works as planned.
That is a potential operational benefit, not a result established by the report. The NAS has not been configured, and no restore-time measurements are available. The distinction matters for an AI fleet because storage failure can interrupt both database-dependent publishing work and the machines used for models and testing. Meyer also says the NAS cannot prevent the recurring kernel panics affecting the database Mac; the intended role is to shorten recovery after a failure, not eliminate one.
The planned safeguards aim to limit both accidental deletion and wider loss. Each Mac would back up under a separate non-admin account with a storage quota; daily snapshots would be inaccessible to those accounts; and an encrypted copy would be sent offsite using restic to Backblaze B2, with Object Lock configured to prevent deletion. These are planned protections, not verified features of the current setup.

Why the Six-Bay Model Was Chosen
Meyer describes the existing system as a small collection of computers rather than a data center. Besides the duplicate-copy incident, he reports that the database Mac has experienced recurring kernel panics since August, at its worst about once every five days. A crash on August 8 caused 2¼ hours of database downtime, according to his account. A local backup could make recovery quicker, but it would not fix the underlying hardware or software instability.
UGREEN’s published specifications, as cited by Meyer, list the DXP6800 Pro with 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. Meyer says the six bays, rather than a measured performance advantage, led him to pay more than he would have for the four-bay model. With six 16 TB disks in RAID 6, he estimates capacity at about 64 TB, although that configuration has not been installed.
The proposed design does not put every workload on the NAS. Meyer says he will keep live database change logs off spinning disks, will not give AI agents administrator credentials, and will not expose the NAS through remote internet access. He also rejects a UGREEN cloud mirror as a substitute for an independent offsite backup. Disk-heavy work is planned for overnight, from 20:00 to 06:00, so the drives can sleep during the working day.
“That was the day I stopped treating a sync service as a backup.”

Setup and Backup Tests Are Pending
As of November 1, the NAS had been delivered and equipped with four 16 TB Seagate IronWolf Pro drives and one NVMe SSD, but it had not been connected to the network or set up. The report says the two initial acceptance tests have not run: Time Machine backups using a non-admin account, and snapshots that remain inaccessible to that account.
The proposed RAID 6 capacity, backup schedule, snapshot protections, offsite encryption and Object Lock configuration are all plans. It is not yet known whether the device will meet the operation’s requirements, how quickly it can restore the database, or whether the planned controls will behave as intended. Meyer says the NAS was bought with personal funds, with no sample, sponsorship or affiliate links; he also says UGREEN has not reviewed the article.
Two Tests Before Network Rollout
Meyer says the NAS must pass both acceptance tests before he keeps it: a Time Machine backup under a non-admin account and snapshots that the account cannot access or delete. If either test fails, he says he will return the NAS. Until setup is complete, the existing backups remain on local Time Machine disks attached to two Macs and an iCloud copy of the nightly database dump.
The site says it plans to report results after the NAS is running. That follow-up will be needed to establish whether the local system improves restore times, whether the access controls work, and whether the planned offsite copy provides a separate layer of protection.
Key Questions
Has the DXP6800 Pro been put into service?
No. As of November 1, 2026, it had been delivered and fitted with drives but was not connected to the network or configured.
Why did the site buy a NAS?
The operator says duplicate iCloud conflict copies nearly filled a database server, while managing old copies also caused a backup job to time out. The NAS is intended to provide a local backup destination and faster recovery source.
How much storage is planned?
The current plan uses four 16 TB drives in RAID 6, which Meyer estimates would yield about 32 TB usable. That layout has not yet been configured or tested.
Will the NAS replace the offsite backup?
No. Meyer’s plan retains an encrypted offsite copy sent with restic to Backblaze B2. He says the NAS will provide local storage, not replace the separate offsite layer.
What could still prevent the NAS from being used?
The system must pass two tests covering Time Machine access and snapshot protection. Meyer says it will be returned if either test fails; performance and restore times also remain unknown.
