Quick answer: the best NAS for a small business backup setup is usually a Synology DiskStation DS224+ for a very small office or a Synology DiskStation DS923+ for a growing team. Choose QNAP TS-464 when faster local storage and flexibility matter, Asustor Lockerstor 4 Gen2 when a technical owner wants value and expansion, UGREEN NASync DXP4800 Plus only after checking ecosystem fit, and WD My Cloud EX2 Ultra for a simpler low-touch shared-storage lane.
A NAS is useful because it gives the office one local place for shared files, backups, archives, and recovery copies. It is also easy to misuse. A NAS should not be the only copy of the business. The safer small-business setup is local NAS plus an external or cloud/offsite backup plus a documented restore test.
Small office NAS backup in 2026: start here
If you are buying a NAS for a small office, choose the box after you define the restore plan. A 2-bay NAS can be enough for one owner or a tiny office. A 4-bay NAS is safer for teams that need more retention, snapshots, shared folders, or room to grow. But the real plan should include local NAS storage, offsite or cloud backup, a UPS battery backup, limited user permissions, and at least one tested restore.
For most small businesses, the NAS belongs beside backup software, external backup drives, secure networking, office Wi-Fi and access-point planning, admin-account security keys, and a simple document workflow. Real estate teams with listing photos, video files, scans, transaction PDFs, and closed-file archives can use the dedicated guide to backup drives and portable SSDs for real estate agents and offices. If your paper intake is still messy, also compare document scanners and document management software before assuming storage alone fixes the workflow.

Check current Amazon listingHow To Choose A NAS For Small Business Backup
Start with the restore problem, not the drive count. Decide what must be recovered first if a laptop dies, a bookkeeper deletes a folder, ransomware hits a workstation, or the office internet goes down during a deadline.
Two bays vs four bays
Two bays can be enough for a tiny office. Four bays give growing teams more room for retention, snapshots, shared folders, and future expansion.
Backup target vs file server
If the NAS is only a backup target, keep it simple. If staff work from shared folders every day, pay more attention to speed, permissions, and support.
Local copy vs offsite copy
A NAS protects against some local problems, but not fire, theft, flood, or every ransomware scenario. Keep an offsite copy.
Who owns it
Someone must own firmware updates, user access, alerts, drive replacement, and restore testing. Otherwise the NAS becomes a mystery box.
For the broader data-protection plan, pair this page with TPTK’s guides to backup software for small business, backup drives for small business, UPS battery backups, VPN routers for small business, and security keys for small business. Real estate offices planning local storage for camera-related records or shared security workflows should also compare security cameras for real estate offices.
Best NAS Devices For Small Business Backup
Synology DiskStation DS224+: Best simple 2-bay NAS
Best fit: Owner-operated offices that want reliable shared files and local backup without building a mini server room.
Why it fits: The DS224+ is the cleanest starting point when a small office needs two-drive redundancy, simple file sharing, user permissions, and a backup target for laptops and desktops.
Watch-outs: It is still a NAS, not a backup strategy. Use it with offsite backup, documented restore tests, and a UPS.
Synology DiskStation DS923+: Best 4-bay NAS for growing teams
Best fit: Small teams that have outgrown a two-drive box and need more room for users, shared folders, and backup history.
Why it fits: The DS923+ is a stronger Synology lane for offices that want four bays, longer backup retention, snapshots, and a setup that can grow more gracefully.
Watch-outs: Budget for drives, backup software, cloud/offsite backup, and the person responsible for updates and restores.
QNAP TS-464-8G-US: Best fast local office NAS
Best fit: Operations desks, media-heavy teams, and offices that care about faster local transfers and flexible expansion.
Why it fits: The TS-464 lane makes sense when the NAS is not just an archive box. It can serve active shared files, project libraries, local app workloads, and faster wired-office storage when configured correctly.
Watch-outs: QNAP systems can be powerful, but they deserve careful security settings, firmware discipline, and limited internet exposure.
UGREEN NASync DXP4800 Plus: Best newer 4-bay NAS to evaluate
Best fit: Owners who want a modern-feeling 4-bay NAS and are comfortable checking app ecosystem fit before committing.
Why it fits: UGREEN's NASync line is an interesting newer lane for small offices that want a more current desktop NAS option with room to grow beyond a two-bay starter box.
Watch-outs: Because it is a newer ecosystem, check backup app support, remote access model, security updates, support expectations, and return terms before building the office around it.
Asustor Lockerstor 4 Gen2 AS6704T: Best advanced value/performance NAS
Best fit: Technical owners or consultants who want a capable 4-bay box and are willing to manage it intentionally.
Why it fits: The Lockerstor 4 Gen2 lane is useful for offices that want performance, expansion, and flexibility without defaulting only to Synology or QNAP.
Watch-outs: It is best for someone who will configure users, shares, remote access, updates, alerts, and backup jobs instead of treating the NAS as a plug-and-forget drive.
WD My Cloud Expert EX2 Ultra: Best preconfigured low-touch NAS lane
Best fit: Very small offices that want a familiar two-bay storage appliance and do not need a deep NAS app ecosystem.
Why it fits: The EX2 Ultra lane can work for simple shared folders and basic local storage when the office wants a preconfigured appliance feel instead of a more expandable NAS platform.
Watch-outs: It is not the best choice for every business. Compare support, firmware, remote access, drive configuration, and long-term backup needs before choosing it over a more flexible NAS.
A Safer Small-Business NAS Setup
For most small businesses, the practical pattern is a local NAS for fast recovery, cloud or offsite backup for disaster recovery, a small UPS to prevent abrupt shutdowns, and a written recovery checklist. If nobody has tested a restore, the backup plan is still theoretical.
What Not To Buy
Avoid buying a NAS only because it has the most bays, the most apps, or the lowest bare enclosure price. Also avoid exposing the NAS directly to the internet without understanding the security model. If the office does not have someone who can manage users, shares, updates, alerts, and restore tests, choose a simpler setup or get help before moving critical files.

If you want the safest first NAS choice for a tiny office, start with Synology DiskStation DS224+. If the team is growing or backup history matters, step up to Synology DiskStation DS923+. Choose QNAP TS-464 or Asustor Lockerstor 4 Gen2 when a more technical owner wants speed and flexibility. Consider UGREEN NASync DXP4800 Plus only after confirming the software ecosystem fits your business. Use WD My Cloud EX2 Ultra only for simple shared storage needs where low-touch setup matters more than expandability.

FAQ
Is a NAS enough for small business backup?
No. A NAS is a useful local backup and shared storage target, but it should not be the only copy. Use local NAS storage with offsite backup and tested restores.
Should a small business buy a 2-bay or 4-bay NAS?
A 2-bay NAS can work for a very small office with simple needs. A 4-bay NAS is better when the team needs more capacity, longer retention, snapshots, or room to grow.
Do I need a UPS for a NAS?
Yes, a UPS is strongly recommended for a NAS because sudden power loss can interrupt writes, damage files, or force an unsafe shutdown.
What is the safest NAS setup for a small office?
The safest setup is a NAS for local backup and shared files, a separate offsite or cloud backup, limited user permissions, security updates, alerts, and a written restore test.
