TL;DR
Thorsten Meyer says his publishing and AI operation bought a six-bay UGREEN NASync DXP6800 Pro after duplicate cloud-sync files nearly filled a database server. As of Nov. 1, 2026, the NAS is equipped but not connected or configured; the planned RAID layout, backup safeguards and acceptance tests remain untested.
Thorsten Meyer has bought a six-bay UGREEN NASync DXP6800 Pro for his small AI and publishing operation after a cloud-sync backup folder produced 29 duplicate database dumps and left one server with 2% free disk space. The unit has been equipped with four hard drives and an NVMe SSD, but as of Nov. 1, 2026, it is not connected to the network or configured, so the proposed backup system has not yet been tested.
Meyer said the duplicates appeared on Sept. 17, when two machines uploaded database dumps with the same filename into one iCloud folder. The service retained conflict copies, and the resulting 29 files nearly filled the database server. On Oct. 29, he said, a nightly backup job also reported an error after deletion of older copies timed out while iCloud was busy. He describes the incident as a failure of copy management, not of the database dump itself.
The current plan is to put four Seagate IronWolf Pro 16 TB drives in RAID 6, which Meyer estimates would provide about 32 TB of usable capacity and tolerate the failure of two drives without data loss. A separate NVMe SSD pool is intended for containers and test databases. The NAS has six SATA bays, but only four hard drives are included in the initial configuration; filling all six with 16 TB drives would yield about 64 TB under the same RAID arrangement, according to Meyer’s estimates.
Meyer says the planned safeguards include separate, non-admin accounts and quotas for Mac backups, daily snapshots that those accounts cannot access or delete, and an encrypted offsite copy sent with restic to Backblaze B2, configured with Object Lock. The NAS will not host a live database change log, provide internet-facing remote access, or serve as the only offsite backup. He said he paid for the hardware himself, received no manufacturer sample or sponsorship, and has no affiliate links in the article.

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.

Why Local Backup Speed Matters
The purchase addresses a recovery and reliability problem, not simply a shortage of storage. Meyer measured the operation’s current backup requirement at about 6 to 8 TB. A local NAS could provide a second on-site storage medium and allow large restores over the local network rather than relying first on a cloud transfer, which he says can take hours for hundreds of gigabytes over the office connection.
The distinction between synchronization and backup is central to the plan. A sync tool can reproduce deletions or unwanted files across devices; Meyer’s account of the repeated dumps illustrates how that can consume storage rather than preserve a clean recovery point. The proposed snapshots and offsite copy are intended to add separate recovery layers. They are still a design, however: no tests have shown that they work as intended on this device.
The NAS is also meant to move Docker-based test databases off Meyer’s laptop, where a virtual disk had grown to about 30 GB. He plans to schedule disk-heavy tasks between 8 p.m. and 6 a.m. and let the drives sleep during working hours. Whether that schedule delivers a quieter office or suitable performance remains to be seen.

From Sync Failures to NAS
Meyer describes an operation built around several Macs: one runs the main PostgreSQL database, another serves local AI models, and others handle publishing workflows and tests. Measurements taken Oct. 6 put storage use at about 2.6 TB on the main desk machine, 744 GB on the database server—including a 293 GB database—and 3.2 TB on the model server. He says much of the model storage can be downloaded again, so it is not the primary backup priority.
The server has also had recurring kernel panics since August, according to Meyer. He said an Aug. 8 incident caused 2¼ hours of database downtime. A NAS cannot prevent a computer crash, but local copies may make restoration faster, he argues. The proposed setup follows the familiar 3-2-1 backup principle: keep multiple copies, use different media, and store one copy offsite. Meyer cites US-CERT guidance for that approach.
He says he selected the six-bay model over a less expensive four-bay option because it leaves room to add drives without replacing the initial set. UGREEN’s published specifications 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. Those are manufacturer specifications, not performance results from Meyer’s use.
“That was the day I stopped treating a sync service as a backup.”

Deployment Tests Still Pending
The hardware has been delivered and equipped, but the NAS is not on the network. The planned RAID 6 pool, SSD pool, user permissions, snapshots, scheduled disk activity and offsite backup have not been demonstrated in operation. Meyer says the two initial acceptance tests are Time Machine backups using a non-admin account and snapshots that backup users cannot access or delete.
It is also not yet clear how quickly the system will restore the database, whether the scheduled drive-sleep plan will work with the workload, or how the chosen configuration will perform in daily use. The reported capacities are planning estimates, and the device’s listed hardware specifications come from UGREEN. Meyer says he will report real results after rollout; this account is not a review or long-term test.
Acceptance Tests Before Rollout
Meyer says the NAS will go back if either of the two initial safeguards fails: a Mac must be able to back up through a non-admin account, and the account must not be able to reach or delete protected snapshots. If both tests pass, the next steps in the published plan are to configure the storage pools, move selected backup and test-database workloads, and establish the encrypted offsite copy.
Until that deployment and testing happen, the existing backup routine remains in place: local Time Machine disks on two Macs and an iCloud copy of the nightly database dump. The next meaningful update will be whether the NAS passes the access-control and snapshot tests, followed by measured results from actual use.
Key Questions
Is the UGREEN NAS already running?
No. As of Nov. 1, 2026, Meyer says it has been delivered and fitted with four hard drives and one NVMe SSD, but it is not connected to the network or configured.
What storage layout is planned?
The plan is for four 16 TB Seagate IronWolf Pro drives in RAID 6, with an estimated 32 TB usable, plus a separate NVMe SSD pool for containers and test databases. These figures describe the intended setup, not a tested result.
Why did Meyer choose a six-bay model?
He says the extra bays provide room to add drives later without replacing the initial set. His current plan uses four of the six bays.
What must pass before the NAS is kept?
Meyer says he will test Time Machine backups through a non-admin account and check that the account cannot access or delete snapshots. He says the NAS will be returned if either test fails.
Will the NAS replace offsite backups?
No. The plan includes an encrypted offsite copy to Backblaze B2 using restic and Object Lock. Meyer says he will not treat a UGREEN cloud mirror as the offsite backup.
