How Often Should You Really Back Up Your Business Data?

"How often should we back up?" is one of those questions that sounds like it should have a single correct answer, but the honest reply is: it depends on how much work you could stand to lose and still recover without serious pain. The right frequency for an accountancy practice handling client data all day is different from the right frequency for a business whose records barely change week to week.

The real question underneath it

A more useful way to frame it is: if your systems failed right now, how much data would you be comfortable losing permanently? If the honest answer is "none, we can't lose even an hour of today's work," your backup frequency needs to reflect that. If it's "we could recreate anything from the last day fairly easily," a daily backup might genuinely be fine. This gap between "how much data could you lose" and "how often do you currently back up" has a name — recovery point objective — but the concept matters far more than the term.

What this looks like for a typical small business

For most small businesses, a daily backup of core systems — files, email, and any line-of-business software or database — is a sensible baseline. Businesses that handle a high volume of transactions, bookings, or client updates throughout the day sometimes need more frequent backups, sometimes running continuously in the background, so that a failure mid-afternoon doesn't mean redoing a full day's work from scratch.

Frequency isn't the only thing that matters

A backup that runs every hour is still worthless if it's never actually been tested and turns out not to restore properly, or if it's stored in the same place as the data it's protecting and gets wiped out alongside it. Three things matter roughly equally: how often it runs, where it's stored (ideally with at least one copy genuinely separate from your main systems, sometimes summarised as the "3-2-1" approach — three copies, on two different types of storage, with one kept offsite), and whether it's actually been tested with a real restore, not just checked for a green tick saying it "completed successfully."

Don't forget retention, not just frequency

It's also worth thinking about how far back your backups go, not just how often they run. If a problem — accidental deletion, corrupted data, or ransomware — isn't noticed for a few days or weeks, you need a backup from before it happened still available to restore from, not just last night's copy of an already-corrupted file.

Worth reviewing properly, not guessing at

If you're not entirely sure how often your current systems actually back up, where those backups are stored, or when they were last tested with a real restore, that's worth finding out properly rather than assuming it's fine.
