DR for SMBs Without an IT Team to Spare

Most disaster recovery writing is written for enterprises. Active-active architectures, multi-region orchestration, dedicated DR engineers, seven-figure RTO targets. That's fine if you have 400 IT staff and a CFO who signs off on eight-digit infrastructure budgets. It's useless if you're a 40-person business with one overworked sysadmin and a $200K total IT spend.

Small and mid-sized businesses need a different playbook. Same principles, radically different execution. Here are six tips from the small-business deployments that actually work.

1. Accept that you will never have enterprise RTOs — and that's fine

The first mental adjustment is the hardest. You are not going to have a 15-minute RTO on your ERP. You are not going to failover your entire environment to a hot-standby region in minutes. You probably don't need to, and you definitely can't afford to.

What you can have is a 4 to 12 hour RTO on your critical systems and a 24 to 48 hour RTO on everything else. If you're a professional services firm and the business can survive a day without the CRM, that's your target. Don't apologize for it, don't let a vendor shame you into spending for something you don't need, and don't design a plan for the RTO you wish you had.

The exercise that matters is asking the business owner: if the office burned down on Friday night, when do we need to be operational again? The honest answer is almost never "Monday morning, 8:00 AM sharp." It's usually "Tuesday or Wednesday is fine, as long as we can call customers and tell them the plan."

Design to that.

2. Put Microsoft 365 or Google Workspace at the center

The single best DR move a small business can make is already done in most cases: they use Microsoft 365 or Google Workspace for email, documents, and collaboration. These services are effectively always-on, geo-redundant, and outside your local failure domain. If the office has a fire, email still works. If ransomware hits the file server, the documents people have been working from in OneDrive or Google Drive are mostly fine.

The catch: Microsoft 365 and Google Workspace are not backed up by default. Microsoft's own documentation says so explicitly. If an employee deletes a folder with 1,200 customer files, you have 30 to 93 days to restore it from the native recycle bin. After that, it's gone.

Add a third-party M365/Workspace backup product. Datto SaaS Protection, Veeam Backup for M365, Barracuda Cloud-to-Cloud, SkyKick — any of them. Budget $3 to $5 per user per month. This is the highest-leverage DR investment a small business can make, and it takes an afternoon to set up.

3. Move the file server to the cloud — not a copy, the actual server

Most small businesses still have a file server in a closet somewhere. It's the highest-risk single asset in the environment because it holds the working data that the business runs on, and it's sitting on the same power and network that would fail in any reasonable disaster.

Stop replicating it. Move it. SharePoint, OneDrive for Business, Google Drive, Egnyte, Dropbox Business — any of them can host the working file store in a way that survives a local event automatically. The migration is not trivial, but it's a one-time project, and it dramatically simplifies your DR story. You don't need to replicate a file server if there is no file server.

The workloads that genuinely need a local file server — large CAD files, video editing, workflows with latency requirements — are narrower than most people think. Audit what's actually on your file server. 80% of it is Word documents and spreadsheets that would be happier in SharePoint.

4. Use your line-of-business vendor's cloud offering whenever possible

For many SMB workloads, the DR problem has already been solved by somebody else — the software vendor. QuickBooks Online instead of QuickBooks Desktop. Salesforce instead of a self-hosted CRM. Shopify instead of a self-hosted ecommerce stack. A hosted practice management system instead of a server in the server room.

Every workload you can move to a vendor-hosted SaaS offering is a workload you no longer have to DR yourself. You still need to back it up (see tip #2 — same problem, same solution: third-party backup for SaaS), but you don't need to architect failover, maintain runbooks, or test recovery procedures.

The trade-offs are real: cost, flexibility, vendor lock-in, integration complexity. But for a small business without the engineering bench to run DR on every workload, this is almost always the right move for any system where a vendor offers a credible hosted option.

5. Buy DRaaS for whatever's left — don't build it yourself

After you've moved email to M365, files to SharePoint, and LOB apps to SaaS, you'll have a small residual set of workloads that still live on-premise: maybe a local ERP that doesn't have a cloud version, a specialty application, a domain controller, a print server.

For that residual set, buy DRaaS. Don't build it. A small business cannot justify the engineering time to stand up a secondary site, configure replication, maintain runbooks, and test failover. The math is not close.

A reasonable SMB-tier DRaaS offering runs $500 to $2,500 per month depending on the size of the protected environment. That's less than the cost of one weekend of engineering time per month, and it includes testing, which you probably weren't going to do on your own anyway.

Look for providers who work with SMBs explicitly. Many of the enterprise-tier DRaaS vendors have minimums that don't make sense for small shops. Axcient, Datto, StorageCraft (now Arcserve), and Acronis all have SMB-focused offerings that fit.

6. Write a one-page incident runbook — and make somebody non-IT accountable for keeping it current

The second-highest-leverage DR investment after backing up M365 is writing down what to do when something goes wrong, on one page, in plain language, and putting it somewhere people can find it without a working network connection.

Not a binder. Not a 40-page formal plan. One page. Items on it:

• Who calls the IT provider or MSP (with phone number, not email)
• Who tells the staff not to come to the office (or to work from home)
• Who calls the key customers
• Who calls the cyber insurance carrier and when
• The emergency credentials envelope (where the break-glass passwords are stored — ideally a sealed envelope in a bank lockbox or with outside counsel)
• Who has authority to approve spending decisions during the incident

Print it. Put a copy in the office, a copy at the owner's home, and a copy with outside counsel. Update it every six months. Assign the update to the office manager or operations lead, not the IT person — because when the IT person is unavailable during the incident, the operations lead needs to know where everything is.

This document will not prevent a disaster. It will dramatically reduce the chaos of the first 60 minutes, which is where most small-business recoveries get off track. The companies that recover well aren't the ones with the best technology. They're the ones where the first hour wasn't wasted figuring out who was in charge.

The Short Version

Small business DR is about making the problem smaller before you try to solve it. Move everything you can to cloud services that are already redundant. Back up what's left. Buy DRaaS for the stubborn residue. Write down what to do. Test it once a year.

Don't try to build an enterprise DR program on an SMB budget. It doesn't work and it distracts from the simpler moves that actually do.
