We hear "we have backups" from almost every business we talk to. And most of them do - somewhere, something is being copied to somewhere else on some schedule. The problem isn't that backups don't exist. The problem is that most businesses have never tested whether they can actually recover from a disaster using those backups. And there's a meaningful difference between "we have copies of our data" and "we can be back up and running in four hours."
Backup vs. Disaster Recovery: The Short Version
Backup is copying data so you have a second copy if the original is lost. It answers the question: "Can we get our files back?"
Disaster recovery (DR) is a plan and infrastructure for restoring entire systems - servers, applications, configurations, and data - to a functional state within a defined time frame. It answers the question: "How quickly can we be operational again?"
A backup protects your data. A disaster recovery plan protects your business.
The Scenarios That Expose the Gap
Consider this: your main server goes down. The hard drives are dead. You have nightly backups on an external drive sitting next to the server. You can recover your files. But what about the server itself? The operating system, the applications, the configurations, the databases? That external drive has your QuickBooks data files, but it doesn't have a working QuickBooks server.
To rebuild from file-level backups, you need to:
- Procure new hardware (1-5 business days, depending on availability)
- Install the operating system
- Install and configure all server applications
- Restore your data onto the rebuilt applications
- Test that everything works
- Reconnect all user workstations to the new server
That process takes days to weeks, depending on complexity. For a business that depends on that server for daily operations, every hour of downtime has a cost - lost revenue, idle employees, missed deadlines, frustrated clients.
Now consider the same scenario with a proper disaster recovery solution: the server goes down. Within minutes, a virtualized copy of that server - operating system, applications, data, and all - spins up either on a local backup appliance or in the cloud. Users connect to it. Work continues. The hardware gets replaced in the background while the business keeps running. Recovery time: hours, not weeks.
Recovery Time Objective and Recovery Point Objective
Two numbers define your disaster recovery posture:
RTO (Recovery Time Objective): How quickly do you need to be operational after a disaster? If your answer is "we can't be down for more than four hours," your RTO is four hours. That means your DR solution needs to be able to restore operations within that window.
RPO (Recovery Point Objective): How much data can you afford to lose? If you back up nightly, your RPO is 24 hours - in a worst case, you lose a full day of work. If you back up every hour, your RPO is one hour. If your business processes $50,000 in transactions per day and you lose a day of data, that's a real problem.
Most businesses we talk to have never defined their RTO or RPO. They just "have backups" and assume it'll work out. It doesn't always.
What a Real DR Solution Looks Like
We use Datto BCDR (Business Continuity and Disaster Recovery) appliances for our clients. Here's what that looks like in practice:
- Image-level backups of your servers - not just files, but the entire system state - taken every hour or more frequently
- Automatic verification that every backup is bootable and functional (screenshot verification)
- Local virtualization capability - if a server fails, the backup appliance can run a virtual copy of that server within minutes
- Cloud virtualization as a second failover - if your entire office is inaccessible (fire, flood, power outage), the same server can spin up in Datto's cloud and your team can connect remotely
- Ransomware detection built into the backup process - anomalies in file change patterns trigger alerts before encrypted backups overwrite good ones
The Test That Matters
The single most important thing about disaster recovery isn't the technology - it's testing. A DR plan that hasn't been tested is a hope, not a plan. We run DR tests for our clients quarterly: we spin up the backup, verify that applications work, confirm that data is current, and document the recovery time. If there's a gap - if recovery takes six hours but the RTO is four - we fix it before there's an actual emergency.
If you have backups but haven't tested a full recovery, the honest assessment is that you don't know if your backups work. We've seen businesses discover during an actual disaster that their backup drive was full and hadn't been running for months, or that the backup was corrupted, or that critical data was stored in a location that wasn't included in the backup scope.
Hope isn't a disaster recovery strategy. If you'd like to know where you actually stand - what your real RTO and RPO are today, and what it would take to align them with your business requirements - we can walk through it with you.
