Data Backups and Recovery: What Happens When Everything Goes Wrong
A backup you have never restored is a guess, not a safety net
The single most important thing about backups is that they must be tested by actually restoring them. Plenty of businesses discover, at the worst possible moment, that their backups were incomplete, corrupted, or never running at all.
A backup is only proven when you have rebuilt from it and checked the result. Until then, it is an assumption you are betting your business on.
Treat restore testing as a routine task, not a fire drill. Doing it calmly on a quiet Tuesday is far cheaper than doing it in a panic on a Friday night.
Two numbers decide your whole strategy
Before choosing tools, decide how much data you can afford to lose, and how long you can afford to be down. These are your recovery point and recovery time targets, and they drive every other decision.
If losing an hour of orders is unacceptable, you need frequent backups or replication. If a day of downtime would sink you, you need a rehearsed, fast recovery path.
Be honest here rather than aspirational. Near-zero loss and instant recovery are achievable, but they cost more, so match the spend to what the data is genuinely worth.
What actually needs backing up
It is more than the database. A working recovery usually needs your database, uploaded files and media, environment configuration, and often third-party data that lives outside your own systems.
Uploaded assets are the classic blind spot. Many teams back up the database religiously and forget the folder full of customer documents and images, which is just as hard to recreate.
Write down every place your data lives, including payment providers, email platforms, and integrations. If your site is the hub for several systems, recovery means getting them talking again too.
Offsite, versioned, and out of reach of ransomware
Good backups are stored away from the live system, kept in multiple versions, and protected so that an attacker or a bad deploy cannot destroy them too. A backup sitting on the same server it protects is not really a backup.
Keep several historical copies, not just last night's. Corruption and ransomware often go unnoticed for days, so a single recent snapshot may already contain the problem.
Immutable or write-protected storage matters here. If someone gains access to your systems, they should not be able to quietly delete your ability to recover.
The honest caveat: recovery is a process, not a button
Restoring data is only part of the job. You also need to know who does what, in what order, and how you communicate with customers while the site is down.
A backup can be perfect and the day can still go badly if nobody knows the DNS settings, the hosting login, or who to call. Document the runbook and keep it somewhere you can reach when your main systems are offline.
Managed hosting and platform providers often include some backup, but check the detail. Retention windows, restore speeds, and what is actually covered vary wildly, and the defaults are rarely enough on their own.
Get your recovery plan tested before you need it
Most businesses only find out how good their backups are during an emergency. A short review now can turn that gamble into a plan you trust.
If you are not certain you could rebuild your site and data tomorrow, that is worth a conversation. We are happy to talk it through honestly.
