To back up your data before a hurricane, follow the 3-2-1 rule: keep three copies of your data, on two different types of media, with one copy stored off-site or in the cloud. If a storm is already named and heading your way, you can get a workable version of this done in about 30 minutes per computer. Here’s the fast version first, then the durable setup to build for the rest of the season.
A rugged external hard drive provides an essential offline backup solution during severe weather and hurricane season.The 30-minute version (storm is coming)
- Identify what actually matters: accounting files, customer databases, contracts, payroll, photos of the office for insurance. Skip programs — they can be reinstalled.
- Copy those files to a cloud drive (OneDrive, Google Drive, Dropbox). If files are too big for your upload speed, prioritize the irreplaceable ones.
- Also copy everything to an external USB drive — this is your second media type.
- Take the external drive with you when you evacuate, or store it somewhere high, dry, and outside the storm’s path.
- Verify: open three or four files from both the cloud copy and the drive. A backup you haven’t opened is not verified.
Why the 3-2-1 rule works in hurricanes specifically
Hurricanes destroy backups in ways everyday failures don’t. A backup drive sitting next to the server drowns with the server. A second copy in a desk drawer across the room burns in the same fire or is looted from the same broken window. The 3-2-1 rule survives because the off-site copy is out of the disaster zone entirely — a data center hundreds of miles away doesn’t care what the Gulf is doing.
The durable setup for hurricane country
Automate it
Manual backups fail because humans forget. Use backup software or a managed backup service that runs nightly without anyone touching it, and — critically — alerts someone when a backup fails. The most common disaster-recovery story we see isn’t “we had no backup.” It’s “the backup had been silently failing since March.”
Back up systems, not just files
File copies save your documents, but rebuilding a server from scratch — Windows, applications, settings, permissions — can take days. Image-based backups capture the whole machine so it can be restored to new hardware or spun up as a virtual machine in the cloud while your office is still without power. That difference is measured in days of downtime.
Know your two numbers: RPO and RTO
RPO (recovery point objective) is how much data you can afford to lose — if the answer is “a day,” nightly backups are fine; if it’s “an hour,” you need continuous protection. RTO (recovery time objective) is how long you can afford to be down. Those two numbers, not any product name, should drive what you buy.
Test a restore before the season peaks
August through October is when Florida takes most of its hits. Pick a quiet week before then and restore a folder, a mailbox, and — if you can — a full server image to spare hardware or the cloud. Time it. That number tells you your real RTO, and the test usually surfaces the one broken thing you’d rather find in July than mid-storm.

Frequently Asked Questions
What is the 3-2-1 backup rule?
Keep three copies of your data, on two different types of media, with one copy off-site or in the cloud. It’s the standard because it survives fire, flood, theft, and hardware failure at the same time.
Is cloud storage enough to protect data from a hurricane?
Cloud storage protects against local destruction, but sync services also sync mistakes and ransomware. Pair a cloud copy with a versioned backup (or a true backup service) so you can roll back to before the problem.
How often should a business back up its data?
At minimum nightly, automated, with failure alerts. Businesses that can’t afford to lose a day of transactions should use continuous or hourly backup for critical systems.
What’s the best way to protect data from flooding?
Get a copy out of the building: an automated off-site or cloud backup, plus an encrypted external drive you take with you when you evacuate. Elevating equipment helps, but off-site copies are what guarantee survival.
