TL;DR
ThorstenMeyerAI.com has bought a UGREEN NASync DXP6800 Pro after duplicate iCloud-synced database dumps nearly filled a server. As of Nov. 1, 2026, the NAS is equipped but not connected or configured; the proposed backup setup and its tests remain unverified.
ThorstenMeyerAI.com has bought a six-bay UGREEN NASync DXP6800 Pro to address problems with its current backup process, after duplicate database dumps synced through iCloud helped leave a server with just 2% free disk space. The NAS has been delivered and equipped with drives, but it is not yet connected to the network or configured, so the proposed setup and its safeguards have not been tested.
The site reports that two machines uploaded database dumps with the same filename to one iCloud folder. iCloud created 29 conflict copies, contributing to the low disk space on the machine running its main database. On Oct. 29, a separate nightly backup job also ran into a timeout while trying to remove old dump copies as iCloud was busy. The publisher says the database backup itself was intact; managing its copies was the problem.
The purchased system is paired with four Seagate IronWolf Pro 16 TB drives and one NVMe SSD. The planned configuration puts the hard drives in RAID 6 for backups, with an estimated 32 TB usable capacity, and uses the SSD as a separate pool for containers and test databases. These are planned arrangements, not results from a completed installation. The company says it paid for the NAS and storage itself; UGREEN did not provide or sponsor the equipment.
According to specifications cited from UGREEN, the DXP6800 Pro has six SATA bays, two M.2 slots, a 10-core Intel Core i5-1235U processor, two 10GbE ports and 8 GB of DDR5 memory, expandable to 64 GB. The publisher says it chose this model over a four-bay alternative for the additional capacity to add drives without replacing the existing ones.

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 specific weakness in the publisher’s setup: syncing files is not the same as keeping an independent backup. A sync service can replicate deletions or unwanted copies, while a local NAS could provide another copy on the office network. That may make restoring large files faster than retrieving them from remote cloud storage, though the publisher has not yet measured restore times on this system.
The reported storage needs are modest by enterprise standards but substantial for a small operation. Measurements taken Oct. 6 put the main desk machine at about 2.6 TB, the database server at 744 GB, and the model server at 3.2 TB, mostly files that can be downloaded again. The publisher estimates its current backup requirement at 6 to 8 TB. A local system could also move test databases off a work laptop, where a virtual disk had grown to about 30 GB.
The plan is designed around limiting the damage a single mistake or account compromise could cause. Each Mac would back up using a separate non-admin account with a storage quota; daily snapshots would be kept beyond those accounts’ reach; and an encrypted offsite copy would be sent to Backblaze B2 using restic, with Object Lock intended to prevent deletion. Those layers are proposed protections, not yet verified safeguards.

Why the Existing Copies Fell Short
The publisher describes a small fleet of Macs that run continuously, including a machine hosting its main Postgres database and another serving local AI models. It says the database Mac has suffered recurring kernel panics since August, at times roughly every five days. A crash on Aug. 8 caused about 2 hours and 15 minutes of database downtime, according to the site. A NAS would not prevent a computer failure, but a nearby backup could help shorten recovery if it works as intended.
Cloud storage still has a role in the proposed design: the publisher plans to keep an offsite copy there. It says the NAS is meant to add a local storage layer, rather than replace remote backup. The article also cites the familiar 3-2-1 backup principle: keep three copies of important data, on two types of media, with one copy offsite. UGREEN’s help center, as quoted by the publisher, warns that its Cloud Drives app’s two-way sync can carry a deletion from one side to the other.
The planned operating rules include scheduling disk-heavy work between 8 p.m. and 6 a.m. so the drives can sleep during office hours. The publisher also says it will not put live database change logs on spinning drives, give AI agents administrator credentials, expose the NAS to direct internet access, or treat a UGREEN cloud mirror as its offsite backup.
“That was the day I stopped treating a sync service as a backup.”

Setup Tests Still Pending
As of Nov. 1, 2026, the NAS had not joined the network, and the publisher had not run either of its stated acceptance tests: Time Machine backup using a non-admin account, and snapshots that the backup accounts cannot access or delete. It is not yet clear whether the planned account permissions, snapshots, RAID configuration or offsite copy will work as intended.
The publisher says its existing backups remain in place: local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. The article is not a review or long-term test, and it does not report measured transfer speeds, recovery times, noise levels, reliability results or the outcome of a restore. The NAS cannot prevent the reported Mac crashes, and its effect on downtime remains unproven.
Acceptance Tests Before Rollout
The next milestone is connecting and configuring the NAS, then testing whether Time Machine can write backups through a non-admin account and whether snapshots remain protected from that account. The publisher says either failed test would be grounds to return the unit. Until those checks pass, its existing backup routine remains the one in use.
ThorstenMeyerAI.com says it plans to report back with results after the NAS is running. That follow-up will be needed to establish whether the planned local and offsite copies improve recovery without introducing new access or management problems.
Key Questions
Is the UGREEN NAS already backing up the publisher’s computers?
No. As of Nov. 1, 2026, it had been delivered and equipped with drives, but was not connected or configured. The publisher says its existing Time Machine disks and iCloud database-dump copy remain in use.
What storage setup is planned?
The plan uses four 16 TB Seagate IronWolf Pro hard drives in RAID 6, with about 32 TB usable capacity, plus an NVMe SSD in a separate pool for containers and test databases. The configuration has not been tested.
Why was the NAS purchased?
The publisher says 29 iCloud conflict copies contributed to a server falling to 2% free disk space, while later cleanup of old copies timed out. It wants a local backup destination alongside an encrypted offsite copy.
Has the setup passed its backup tests?
No. Tests of Time Machine with a non-admin account and snapshots inaccessible to that account were still pending. The publisher says it will return the NAS if either test fails.
