Small business: is a NAS enough, or do you need a server?

If you only need file sharing the answer differs from if you need to run applications.

A question we get often. The answer depends on whether you need more than file sharing.

What a NAS does

A NAS is network-attached storage. Its core job is sharing files, and it does that well.

What it handles:

  • Shared file storage with folder-level permissions
  • Acting as a backup target
  • Basic camera recording
  • Cloud synchronisation

The advantages: cheap, quiet, small, simple to set up. For a small office it is often enough.

What a server does

A server is a general-purpose computer. You decide what runs on it.

What a NAS cannot do:

  • Domain management. Central user accounts, one password for everything, policy distribution.
  • Running business applications. Accounting, ERP and production systems need a server.
  • Hosting databases.
  • Virtualisation. Running several virtual machines seriously.

The cost: more expensive, larger, noisier, needs management, and carries licence cost.

Three questions to decide

1. Do you want central user accounts?
Cutting off access from one place when someone leaves, one password everywhere, a new machine ready in five minutes. If yes, you need a server.

2. Will a business application run on it?
If your accounting or ERP software requires a server, the discussion ends there.

3. How many users?
Under about ten users with only file sharing, a NAS is probably enough. Above twenty, the need for central management asserts itself.

Using both

The most common and usually the best arrangement: the server does the work, the NAS holds the backups.

The server runs the domain, the applications and the database. The NAS takes the server's backups and holds a second copy.

This is better than either alone and the cost is reasonable for most businesses.

The common mistake

Using the NAS as both working storage and backup. If your live data and your backup sit on the same device, you do not have a backup.

If the device fails, is stolen or is hit by ransomware, both go together. The backup needs to be somewhere else — at minimum a different device, preferably with an offline copy.
