How Often Should You Back Up Business Data?
A plain-English guide to backup cadence — how often is often enough, why "how much can you afford to lose" is the real question, and how to set a schedule that actually protects your business.
There’s a comforting belief that trips up a lot of businesses: “we’ve got backups, so we’re fine.” The kit is running, a green tick shows up somewhere, and everyone moves on. The trouble is that “we have backups” and “we can get our business back after something goes wrong” are two very different statements — and the gap between them is almost always frequency.
How often you back up decides how much work you lose when something fails. That’s the real question hiding inside “how often should we back up?” — not a schedule for its own sake, but a decision about how much you’re prepared to redo when a drive dies, a laptop is stolen, or ransomware locks the lot.
The misconception: a backup is a one-time safety net
Backup isn’t a thing you own — it’s a thing you do, on a rhythm. A copy from three weeks ago will happily restore your business to three weeks ago. Every invoice raised, email sent and file edited since then is simply gone.
So the useful way to frame it isn’t “do we have a backup?” It’s “if everything broke right now, how far back would we be thrown, and could the business live with that?” Answer that honestly and the right frequency falls out almost by itself.
The real question: how much can you afford to lose?
In the trade this is called your recovery point objective, or RPO. It sounds technical, but it’s plain common sense: your RPO is the maximum amount of data you can stand to lose, measured in time. Back up once a day and your RPO is a day — a failure could cost you up to a day’s work. Back up every hour and it’s an hour.
The trick is to set it from the pain, not from the technology. For each type of data, ask: if we lost everything since the last backup, how bad would that be? A quiet marketing folder losing a day is an inconvenience. Your accounts system or live customer records losing a day is a very bad week.
That’s why one blanket schedule rarely fits. Different data earns different frequency:
- Live, business-critical systems — accounting, case management, customer databases, shared working files. These change constantly and hurt most when lost, so they want frequent backups: several times a day, or continuous.
- Important but slower-moving data — HR records, finished projects, reference archives. Daily is usually plenty.
- Rarely-changing or easily-rebuilt data — software installers, static resources. Weekly, or whenever it changes, is fine.
A sensible default for most small businesses
If you want a starting point rather than a lecture, this is a fair one for a typical small or mid-sized business:
- Daily automated backups as the baseline, running overnight so nobody has to remember. An automatic backup that just happens beats a perfect one that depends on a person.
- More frequent backups for your critical systems — hourly or continuous for the handful of things you genuinely couldn’t run without for a morning.
- At least one copy kept off-site or in the cloud, separate from your office, so a fire, flood or theft can’t take your data and its only backup together.
- A retention policy so you’re not only holding yesterday’s copy — keep recent backups frequently, plus older snapshots stretching back weeks or months.
A widely used rule of thumb is 3-2-1: three copies of your data, on two different types of storage, with one kept off-site. It’s old advice, and it still holds up because it protects you from more than one failure at once. This is the shape of a proper backup and continuity setup rather than a single hopeful copy on a USB drive.
The mistake that undoes good intentions
Two traps catch even careful businesses.
The first is assuming Microsoft 365 or Google Workspace backs itself up. It doesn’t, not in the way you’d want. Those platforms sync and keep files highly available, but sync is not backup — if a file is deleted, corrupted, or encrypted by ransomware, that change happily propagates to every copy. A separate backup of your Microsoft 365 or Google Workspace data is one of the most common gaps we find, and one of the easiest to close.
The second is never testing a restore. A backup you’ve never restored from is a promise, not a guarantee. Backups fail quietly — a job that stopped running months ago, a set that’s been silently corrupt, a copy missing the one folder that mattered. The only way to know your backup works is to actually bring data back from it, on a schedule. When people come to us after a failure hoping data recovery can save them, it’s often because a backup they trusted turned out to be empty, out of date, or covering the wrong thing.
Putting it together
You don’t need a complicated setup. You need a frequency that matches how much you can afford to lose, a copy kept somewhere safe and separate, backups that run without anyone remembering, and a habit of testing that they actually restore. Get those four right and a failed drive or a ransomware scare becomes an annoyance rather than a crisis.
If you’re not sure what your backups actually cover, or how far back a bad day would set you, we’re happy to take a look and give you a straight answer. It’s a short conversation that tends to be a lot cheaper than finding out the hard way — get in touch and we’ll talk it through.
Frequently asked questions
What is a recovery point objective (RPO)?
Your RPO is the most data you can afford to lose, measured in time. If you back up every hour, your RPO is one hour — a failure could cost you up to an hour of work. It's the honest way to talk about backup frequency, because it starts from the impact on your business rather than from an arbitrary schedule.
Is a backup the same as sync in Microsoft 365 or Google Workspace?
No, and this trips a lot of people up. Sync copies your current files between devices and the cloud — including your mistakes. If a file is deleted, corrupted or encrypted by ransomware, that change syncs everywhere. A proper backup keeps separate, dated copies you can roll back to, which is why we recommend a third-party backup on top of Microsoft 365 or Google Workspace.
How long should we keep old backups?
Longer than most people expect. Some problems — a quiet corruption, a deletion nobody noticed, a compliance request — only surface weeks or months later. A common pattern is frequent recent backups kept short-term, plus periodic snapshots retained for months or years. The right retention depends on your sector and any rules you work under.
