TL;DR
ThorstenMeyerAI.com says it bought a UGREEN NASync DXP6800 Pro after backup sync conflicts nearly filled a database server and cleanup later timed out. The NAS has been equipped with four 16 TB drives and an NVMe SSD, but is not yet connected or configured; the proposed backup design still needs to pass two tests.
ThorstenMeyerAI.com has bought a six-bay UGREEN NASync DXP6800 Pro after duplicate cloud-sync files nearly filled the server holding its publishing database. The NAS has been delivered and fitted with four 16 TB hard drives and an NVMe SSD, but it is not connected to the network or configured, and the planned backup system has not yet passed its acceptance tests.
The immediate trigger came on September 17, when the database server had only 2% free disk space. Thorsten Meyer, writing on the site, said two machines had uploaded database dumps with the same filename to an iCloud folder. The resulting conflict handling produced 29 duplicate copies. A separate cleanup problem surfaced on October 29, when a nightly job timed out while trying to remove old copies from the busy iCloud folder.
The NAS is intended to provide a local destination for backups and a separate place to run test databases. The planned storage layout uses four Seagate IronWolf Pro 16 TB drives in RAID 6, which the article estimates would provide about 32 TB of usable capacity and tolerate the failure of two drives. The NVMe SSD is planned as a separate pool for containers and test databases. These are proposed settings, not results from a completed installation.
Meyer says the purchase was made with personal funds. The article says UGREEN did not provide the hardware or sponsor the piece, and that the company had not reviewed it. Meyer also describes the article as neither a review nor a long-term test. The site’s existing backups remain in place: local Time Machine disks on two Macs and an iCloud copy of the nightly database dump.

Six bays, two fast slots, two 10GbE ports
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 a small operation that runs Macs for a publishing system, local AI models, content pipelines and testing. On October 6, the site measured about 2.6 TB on its main desk machine, 744 GB on the database server and 3.2 TB on its model server. Meyer puts the current backup requirement at roughly 6 to 8 TB. The concern described is not simply a shortage of storage: it is that a sync service can replicate a mistake, while managing old copies can fail when the service is busy.
A local NAS could make large restores quicker than retrieving hundreds of gigabytes over the office internet connection, according to the article. It would also add an on-site storage medium rather than relying on cloud sync as the main backup path. That benefit is still prospective: the device has not been tested in this environment, and it would not prevent the server crashes Meyer reports.
The plan also reflects a security trade-off. A network storage device adds capacity and control, but it needs carefully limited access and another copy outside the office to address theft, damage or other site-wide loss. The article proposes separate non-admin accounts and quotas for each Mac, snapshots protected from those accounts, and an encrypted offsite copy. Whether those controls work as intended has not yet been established.

How Sync Problems Led to the Purchase
Meyer describes the operation as a handful of Macs rather than a data center. One machine holds the main Postgres database; another runs local AI models. Some stored files, particularly model files, can be downloaded again, while the database and publishing data need reliable recovery. The reported database itself was about 293 GB, within a server using roughly 744 GB in total.
The article says the database machine has experienced recurring kernel panics since August, at its worst roughly once every five days. One incident on August 8 caused about 2¼ hours of database downtime. Meyer says the NAS cannot stop a crash, but a local restore might shorten recovery compared with downloading a large backup from the cloud. The planned system is designed around backups, not live database change logs on spinning disks.
The site cites the familiar 3-2-1 backup approach: keep three copies of important data, on two types of media, with one copy offsite. Its proposed arrangement would pair local NAS storage with separate offsite storage through restic to Backblaze B2, with Object Lock intended to limit deletion. Meyer says the plan excludes internet-facing remote access, admin credentials for AI agents and a UGREEN cloud mirror as the offsite backup.
“That was the day I stopped treating a sync service as a backup.”

Deployment Tests Still Pending
The biggest unknown is whether the proposed setup will work reliably with this fleet. As of November 1, 2026, the NAS had not been placed on the network, and neither of the two stated acceptance tests had run. The article does not report measured backup or restore speeds, snapshot behavior, noise levels, power use, or sustained performance.
The stated 32 TB usable capacity is an estimate for the planned four-drive RAID 6 arrangement, not a measured result. The article also describes possible future expansion to six 16 TB drives and about 64 TB under RAID 6, but that configuration is not installed. It remains unclear when rollout will begin, whether either acceptance test will fail, and how the offsite copy will perform in practice.
The reported figures come from Meyer’s own measurements, while product specifications are attributed to UGREEN and Seagate. The source does not provide independent testing of the hardware or evidence that the proposed safeguards have been configured. The piece says Meyer will report results after the NAS is running.
Two Gates Before Network Rollout
The next step is to connect and configure the NAS, then test Time Machine backups using a non-admin account and confirm that the account cannot access or delete the planned snapshots. Meyer says the system will be returned if either test fails. The article does not give a date for those tests or a target date for the full rollout.
If the device passes, the plan is to direct Mac backups to the RAID 6 storage, keep containers and test databases on the separate NVMe pool, and run disk-heavy work between 20:00 and 06:00 so the drives can sleep during office hours. The proposed offsite copy would use encrypted restic backups to Backblaze B2 with Object Lock. Those steps remain a plan until configuration and recovery tests are reported.
Key Questions
Has the UGREEN NASync DXP6800 Pro been installed?
No. As of November 1, 2026, it had been delivered and equipped with four hard drives and an NVMe SSD, but it was not yet connected to the network or configured.
Why did ThorstenMeyerAI.com buy a NAS?
The site says duplicate iCloud sync copies nearly filled its database server, and a later cleanup job timed out. It wants a local backup destination that may allow faster recovery, while retaining an offsite copy.
How much storage is planned?
The proposed layout uses four 16 TB drives in RAID 6, estimated by the article at about 32 TB usable capacity. That is a planned configuration, not a tested result.
What tests must the NAS pass?
The site plans to test Time Machine backups with a non-admin account and verify that the account cannot access or delete snapshots. Meyer says the NAS will be returned if either test fails.
Will the NAS replace the offsite backup?
No. The proposed design keeps an encrypted offsite copy using restic and Backblaze B2, with Object Lock intended to restrict deletion. The NAS itself is planned as local storage, not the only backup.
