Files and Collaboration: Nextcloud as Your Own Drive

Part 5 of 8 in the Linux Business Playbook.

Every business runs on files. Quotes, contracts, photos from the job site, the spreadsheet that holds everything together. Most small businesses keep them in Google Drive, OneDrive or Dropbox, and pay a monthly fee per person for the privilege. That works, until the day you wonder where those files actually live, who else can read them, and what happens to the bill as the team grows.

Nextcloud is the answer to that question for businesses that want to stay in control. This part of the playbook explains what it is, what it does well, where it falls short, and how one small firm uses it alongside the Microsoft tools their staff already know.

What Nextcloud is, in plain words

Nextcloud is your own Google Drive or SharePoint. It is free, open-source software that runs on a Linux server you control. That server can be a small box in your office, or a rented machine in an Australian data centre. Either way, the files sit where you decide, and only your business has the keys.

Staff use it the same way they use any cloud drive. There is a folder on every PC that syncs automatically, an app on every phone, and a web page for the browser. Nobody needs to learn Linux to use it. Linux is simply the engine underneath.

What it does

Nextcloud started as file storage and has grown into a full collaboration suite. As of late 2026 the main pieces are:

• Files: shared folders, automatic sync to every desktop and phone, version history so you can roll back a mistake, and file locking so two people do not overwrite each other.
• Sharing: send a link to a client or supplier with a password and an expiry date, so a quote shared today cannot be opened in six months by someone who forwarded the email.
• Calendar and contacts: shared team calendars and address books that connect to Outlook, Thunderbird, iPhone and Android.
• Talk: video calls, screen sharing and persistent chat rooms, all routed through your own server rather than a third party.
• Office: open and edit Word, Excel and PowerPoint files in the browser, with several people working on the same document at once. Nextcloud offers this through OnlyOffice or Collabora, both of which read and write Microsoft formats.

Why a business might want it

Your data stays yours. If you serve clients in law, health, finance or government, you likely have obligations under the Australian Privacy Act, and clients increasingly ask where their information is stored. "On our server in Brisbane" is a short, confident answer.

No per-user fee. Cloud drives charge per seat. Nextcloud costs the same whether five people use it or fifty. For a growing business the saving is real, and the cost becomes a fixed line rather than a creeping one.

It fits a Linux workplace. If you have followed the earlier parts of this playbook and moved desktops to Linux, Nextcloud's desktop client is native there, with the same experience on Windows and Mac for anyone still on those.

Why it might not be for you

Honesty matters here. When you run Nextcloud, you own the server. That means you own the backups, the updates and the security patches. A cloud provider does those things invisibly. With Nextcloud, somebody has to do them visibly.

For a one-person business with nothing sensitive, that overhead probably outweighs the benefit, and a standard cloud drive is fine. For a business with sensitive client data, a team of five or more, or a bill that keeps growing, the overhead is small compared with what you get back, and it is exactly the kind of work a managed IT partner takes off your hands.

It coexists; it does not have to replace

Adopting Nextcloud does not mean abandoning Microsoft 365 or Google Workspace overnight. Many businesses keep Outlook for email, keep Teams for meetings, and use Nextcloud only for the files that matter most. Start with one folder, one team, one purpose, and expand when it proves itself.

Worked example: a small law firm in Brisbane

A three-partner firm with two support staff handles conveyancing and wills. Client files include identity documents, financial statements and signed deeds. The partners were uneasy about these sitting in a US-run cloud account shared with everyone's personal downloads.

Their setup now looks like this:

• Where it lives: a Nextcloud server in a Brisbane data centre, backed up nightly to a second location, managed by their IT provider.
• Who gets in: every login requires two-factor authentication, a code from the phone as well as a password. A lost laptop is an inconvenience, not a breach.
• How files are organised: one folder per matter. The solicitor on that matter and the support staff assigned to it can see it. Nobody else can.
• Sharing with clients: when a contract is ready, the client receives a link that needs a password and stops working after 14 days. No attachments floating around in email forever.
• What did not change: email still runs through Outlook and Microsoft 365. The partners still use Word. Nextcloud handles where the finished documents live and who can reach them.

The firm's monthly cost for file storage is now fixed, their answer to "where is my data" is one sentence long, and their new starter was working on day one because the sync folder looked just like the drive they used at their last job.

What still needs Windows

For files and collaboration, almost nothing. The Nextcloud desktop app runs on Linux, Windows and Mac, and the phone apps cover iPhone and Android.

The exception is specialist document-management software written for a single industry, such as some legal practice-management or engineering drawing systems, which are Windows-only desktop programs. Those are a separate decision. Nextcloud can still hold the documents they produce, and we cover how to deal with Windows-only software in the 30-day migration plan.

Key takeaway

Nextcloud lets a small business own its files the way it owns its office: a fixed cost, a known address, and your name on the door. It runs quietly on Linux, looks like any other cloud drive to your staff, and works alongside the Microsoft or Google tools you already pay for. The trade-off is that someone must look after the server, and that is a job worth handing to a partner so you can get on with the business.
