The costly mistake with a NAS is treating RAID as a backup. A two-bay box mirroring two drives protects you if one disk dies, but it does nothing when ransomware encrypts your files, you delete a folder by accident or the unit is stolen. What makes a NAS a backup device is the software that copies your computers to it on a schedule, keeps old versions, and ideally pushes a second copy somewhere else.

We reviewed eight diskless NAS enclosures from their spec sheets and listings, ranking them by backup software, network speed, processor and memory headroom, bay count and the cost of getting started. Every unit ships without drives, so budget for disks on top. Price buckets replace exact prices, and where a listing is silent we say so.

Before you buy

What Actually Matters

01

Backup software

A NAS only protects you if it copies your computers on a schedule. Look for named tools such as Active Backup for Business or Hybrid Backup Sync, and for versioning or snapshots. A listing that only says file server is not a backup solution.

02

RAID is not a backup

RAID 1 mirrors two drives so one can fail without data loss. It will not save you from ransomware, deletion or theft. Treat RAID as uptime protection and use versioned backups plus an off-site copy as your actual safety net.

03

Network port

A gigabit port moves roughly 100MB per second at best, and 2.5GbE more than doubles that. The first backup of a large computer can take a day on gigabit. Check that your router and computer also support 2.5GbE before paying for it.

04

Processor and memory

Backup is light work, but multiple computers, snapshots and cloud sync add load. 1GB is thin, 4GB is comfortable and 8GB suits busy households. Check whether RAM is upgradeable, since the Synology DS223 has fixed memory.

05

Drives and capacity

Every NAS here ships diskless, so you must buy drives. Choose NAS-rated disks, and plan for at least double the data you protect, to keep several versions. Four-bay units allow RAID 5 or 6 for more usable space.

Our Ranked Picks, Reviewed

1

Best Backup Software

Synology DS223 Home & Office Backup Hub

Our verdict: A two-bay NAS with free full-image PC and Mac backup through Active Backup for Business.

The DS223 is a two-bay diskless NAS with RAID 1 support, and it includes Active Backup for Business, which the listing describes as free full image backup for PCs and Macs. The DSM scheduler adds versioned backups, so you can roll back to an earlier state of a file. The RAM is fixed and cannot be upgraded.

It wins because the software is the whole point of a backup NAS, and Synology has the most mature option here. Image-level backup means you can restore an entire machine after a drive failure, not just documents. Versioning protects against ransomware and accidental deletion. The cost is hardware: the processor and fixed memory are modest next to the newer rivals, and the network port is the standard kind rather than 2.5GbE.

Buy it if you are backing up two or three computers and want the most reliable set-and-forget software. Skip it if you plan to edit video straight from the NAS.

Best for Multiple Computers

UGREEN NAS DXP4800 Plus

Our verdict: A four-bay NAS with an Intel Pentium Gold 8505 and RAID 5, 6 and 10 for bigger households.

The DXP4800 Plus is a four-bay diskless NAS built around an Intel Pentium Gold 8505 five-core processor. It supports RAID 5, 6 and 10, handles several backup jobs at once and has the highest capacity ceiling in this ranking.

It takes second place because four bays change what a NAS can be. RAID 5 or 6 gives you more usable space than a mirror while surviving a disk failure, and the faster processor stops simultaneous backups from queuing. For a home with three or more computers, or a small office, that headroom matters. It ranks below the Synology only because UGREEN's software is newer, with less track record on backup specifically, and the $500 and up price is a big step.

Buy it if you have many computers, large photo or video libraries, or expect the household to grow. Skip it if you back up one laptop.

Best for Concurrent Jobs

QNAP TS-264-8G-US 2-Bay Desktop NAS

Our verdict: 8GB of RAM, 2.5GbE and Hybrid Backup Sync, the roomiest two-bay in this ranking.

The TS-264 has 8GB of RAM, the most for a two-bay model in this list, plus 2.5GbE networking and Hybrid Backup Sync for local and cloud jobs. QNAP's QTS operating system includes a full app store.

It ranks third because memory and 2.5GbE let it run several backup and cloud-sync jobs without a bottleneck, and Hybrid Backup Sync gives you an off-site copy. The tradeoff is complexity: QTS has more options than DSM and a steeper learning curve, and the app store invites you to run a dozen services you may not need. It sits below the UGREEN four-bay only on capacity, since it has two bays.

Buy it if you want to run backup, cloud sync and a few other apps at the same time. Skip it if you want the simplest possible set-up.

Best Intel Headroom

TERRAMASTER F2-425

Our verdict: An Intel x86 quad-core, 4GB of RAM and 2.5GbE in a two-bay enclosure.

The F2-425 pairs an Intel x86 quad-core processor with 4GB of RAM and a 2.5GbE LAN port in a diskless two-bay enclosure. TOS, TerraMaster's operating system, handles scheduled backups.

It lands fourth because the hardware is strong for the price and leaves room for other light services alongside backup. An x86 chip also means broad software compatibility. The downside is software maturity: TOS has fewer polished backup tools than Synology's, and the listing does not mention full image backup or built-in cloud sync. It is a capable platform, but you may spend more time configuring it.

Buy it if you are comfortable setting up a NAS and want Intel horsepower for backup plus a media server or two. Skip it if you want one-click, image-level backup out of the box.

  • −Image backup is not listed

Buy it if: Tinkerers who want backup plus light services.

Skip it if: You want one-click full image backup.

5

Best for Large Media Files

UGREEN NAS DXP2800

Our verdict: A two-bay, content-creator tier NAS with scheduled rsync, cloud sync and snapshot versioning.

The DXP2800 is a two-bay NAS with content-creator tier hardware and a higher-performance CPU for large file sets. It runs scheduled rsync and cloud-sync backup jobs, with snapshot-based versioning, on UGREEN's own OS and app ecosystem.

It places fifth because it is built for big files, such as photo catalogs and video projects, more than for plain document backup. Snapshots give you point-in-time recovery, which is useful against accidental deletes. It ranks below the Synology because the software is younger and there is no dedicated image backup tool named on the listing, so full-system restores are less certain.

Buy it if your computers hold large media libraries and you want a faster processor than the entry models. Plan a secondary off-site copy, since a single box in one room is not a full strategy.

Best QNAP Entry Point

QNAP TS-216G-US 2-Bay 2.5GbE Desktop NAS

Our verdict: A two-bay QNAP with 2.5GbE and Hybrid Backup Sync, for faster first backups.

The TS-216G is a two-bay desktop NAS with a 2.5GbE port, Hybrid Backup Sync for scheduled local and cloud jobs, QNAP's QTS operating system and standard two-bay RAID support.

It ranks seventh because it overlaps heavily with the TS-264 above but offers less. The listing gives no RAM figure, so headroom for concurrent jobs is uncertain, and the price sits in the same $200 to $500 bracket. Where it makes sense is a network that is already 2.5GbE or about to be, and a buyer who prefers QNAP's software.

Buy it if you want QNAP's backup tools and faster first backups at a fair price. For a bit more, the TS-264 gives much more RAM headroom.

  • −TS-264 offers more for little extra

Buy it if: QNAP fans on a 2.5GbE network.

Skip it if: You want the most RAM for the money.

Best Entry 2.5GbE

Asustor Drivestor 2 Gen 2 AS1202T

Our verdict: A quad-core 1.7GHz two-bay with 1GB DDR4 and 2.5GbE, in the $100 to $200 bracket.

The Drivestor 2 Gen 2 is a two-bay NAS with a quad-core 1.7GHz processor, 1GB of DDR4 RAM and 2.5GbE networking. Asustor's ADM operating system has backup apps for Windows and Mac, and the unit can act as a 4K media server.

Its best argument is 2.5GbE at the lowest price in this ranking. A first backup of a big drive can take many hours, and a faster network port shortens it, provided your router and computer also support it. The 1GB of RAM is thin, so running a media server alongside backup jobs can slow things down.

Buy it if you are a first-time NAS buyer who wants 2.5GbE without the mid-range price. Check that your computer has a matching port, or the speed advantage will not appear.

Questions

Frequently Asked Questions

Do I need to buy hard drives separately?+

Yes. Every NAS in this ranking is sold diskless, so budget for one or two NAS-rated drives. Pick disks with at least double the capacity of the data you want to protect, so you can keep older versions.

What is the most common mistake with a backup NAS?+

Believing RAID is a backup. RAID keeps the box running if a disk fails, but it cannot restore a deleted or encrypted file. Use versioned backups and keep a second copy off-site or in the cloud.

Is the Synology DS223 worth it over a cheaper UGREEN?+

For backup, yes. The free Active Backup for Business image tool and the mature DSM scheduler are stronger than the scheduled jobs on newer rivals. If you only protect one computer with small files, the Asustor Drivestor 2 is enough.

How hard is setup?+

Install the drives, connect power and Ethernet, then follow the web-based wizard. Most buyers have a first scheduled backup running in under an hour. The first full backup can take many hours over gigabit.

Will it work with both Windows and Mac?+

Yes. Synology's Active Backup for Business covers PC and Mac images, and Asustor's ADM lists backup apps for Windows and Mac. For the others, check the maker's supported clients before you buy.

Do I still need cloud backup?+

Ideally, yes. A NAS in the same room does not protect against fire, theft or a power surge. QNAP's Hybrid Backup Sync and UGREEN's cloud sync can push a copy off-site automatically.

Final take

For most households, the Synology DS223 is the best NAS for automatic computer backup, with free image-level PC and Mac protection and versioning. Larger homes and small offices should look at the UGREEN DXP4800 Plus, while the QNAP TS-264 suits people who run many jobs at once. The Asustor Drivestor 2 is the budget route for a single computer. Whatever you choose, add an off-site copy.
