Backing up your dental clinic's patient data

Ask any clinic that has lost a hard drive full of patient records how it felt, and you will understand why backups matter. Patient data is both irreplaceable and confidential, which means protecting it has two jobs: making sure you never lose it, and making sure the wrong person never reads it. This guide covers both, in plain terms.

It applies whether your records are on paper being scanned, in a cloud tool, or in a local-first app on your own computers. The principles are the same.

Why a single copy is a single point of failure

If your patient records live in one place, on one computer, then that computer is a single point of failure. Drives fail, laptops are stolen, and ransomware encrypts whatever it can reach. None of these are rare. A record you cannot recover is, for practical purposes, a record you have lost, so the goal is simple: never have just one copy.

The 3-2-1 rule

The most widely recommended backup principle is 3-2-1: keep three copies of your data, on two different kinds of media, with one copy kept off site. For a small clinic that can be as simple as the working copy on your computer, a scheduled backup to an external drive, and a second backup kept somewhere else. The exact tools matter less than the habit of having more than one copy in more than one place.

Encryption at rest: the confidentiality half

Backups solve availability, but not confidentiality. A backup drive that anyone can plug in and read is a data breach waiting to happen. Encryption at rest means the data is stored scrambled, so a lost or stolen drive is useless without the key. Any patient data you keep, and every backup of it, should be encrypted at rest as a matter of course.

Local-first means the responsibility is yours

With a cloud tool, backups are the vendor's job, but so is access to your data and its privacy. With a local-first tool, your records stay on your own machines, which is exactly the control many clinics want, but it also means backups are your responsibility. That is a fair trade only if the software makes backups easy, ideally automatic, so the responsibility does not depend on you remembering.

What good looks like

A healthy setup for a small clinic looks like this: patient records encrypted at rest on the working machine, automatic scheduled backups so you are never relying on memory, at least one backup kept off the premises, and a periodic test that a backup actually restores. That last step is the one everyone skips and the one that matters, because a backup you have never restored is only a hopeful guess.

A note on syncing between machines

If several computers in the clinic share patient data, that sync is not a backup, but it does add resilience: the same records exist on more than one machine, so a single failure is less catastrophic. Treat it as one layer, and still keep real backups. Sync keeps the team current; backups let you recover.

The backup checklist

For a small dental clinic, aim to be able to say yes to all of these:

  • Do patient records exist in more than one place?
  • Do backups run automatically, not only when someone remembers?
  • Is at least one copy kept off the premises?
  • Is the data encrypted at rest, including the backups?
  • Have you actually restored a backup to confirm it works?
  • Do you control the data, so you can back it up on your own terms?

How HM Praxis handles it

HM Praxis stores patient records locally and encrypted at rest with SQLCipher. A manual backup is always one click away, and the backup scheduler (a Pro feature) lets you set it up once: choose a destination folder, a frequency, and how many copies to keep, and it takes care of the routine from then on. To be clear about the boundaries: nothing is ever backed up to our servers, the scheduler is something you enable rather than something that runs out of the box, and the off-site copy in the 3-2-1 rule stays in your hands, for example by copying the backup file to a drive or storage you keep elsewhere. On the Pro plan, local-network sync also keeps the same records on more than one machine in the clinic, one more layer on top of real backups. And because the database is a file you hold, you can always keep your own copy.
