A well-organised filing system, covered in our guide on building a simple digital filing system, solves the problem of finding a document when you need it. It does not, on its own, protect against losing everything if a device fails, an account is compromised, or a file is accidentally deleted. A backup routine addresses that separate, equally important concern.
The core principle: more than one copy, in more than one place
The fundamental idea behind any reliable backup approach is simple: keep important documents in at least two genuinely separate locations, so that whatever might cause you to lose one copy — a broken device, a deleted account, a corrupted drive — is unlikely to also affect the other at the same time.
A simple two-location routine most people can maintain
- Your primary, organised filing location — wherever you normally keep and access your documents day to day.
- A separate backup location, genuinely independent of the first — a different cloud service, an external drive kept separately, or both.
- A regular, simple habit of copying new or updated documents to the backup location, ideally as part of the same routine you already use for filing them in the first place.
Why "genuinely separate" matters more than people initially assume
Two folders on the same physical device, or two accounts with the same cloud provider tied to the same login, do not provide the same protection as two truly independent locations — a device failure or an account compromise can affect both simultaneously if they are not genuinely separate. A real backup should be able to survive whatever specific problem might affect your primary copy.
Making the backup step effortless enough to actually happen
A backup routine that requires significant manual effort each time is one that tends to be skipped once life gets busy. Where possible, use a cloud storage service with automatic syncing, so files are backed up continuously without requiring an active, separate step every time, rather than relying entirely on remembering to manually copy files on some regular schedule.
What specifically deserves backup priority
- Identity and legal documents — ID scans, contracts, certificates — which can be genuinely difficult or impossible to replace.
- Financial records needed for tax or accounting purposes.
- Irreplaceable personal items, like digitized old family photos, covered in our guide to digitizing old family photos the right way.
- Active business records, if you run a small business, following the approach in our guide to keeping customer documents organised.
Testing that your backup actually works
A backup you have never actually tried to restore from is an assumption, not a verified safety net. Periodically, pick a file from your backup location and confirm you can genuinely open and use it, rather than only discovering a problem with the backup itself at the exact moment you actually need it.
Keeping the routine simple enough to maintain long-term
An elaborate, multi-step backup system that is technically more thorough but genuinely tedious to maintain often ends up abandoned after the first few months. A simple, mostly automatic two-location approach that you will actually keep following consistently protects you better in practice than a more sophisticated system that quietly stops being maintained.
Testing that a backup actually restores correctly
A backup you've never tested restoring from is only a backup in theory. Periodically pick a file from your backup and confirm you can actually open it successfully, rather than assuming the backup process is working correctly just because it appears to run without an error message. A backup that silently fails partway through, or that saves a corrupted copy, only becomes apparent at the worst possible moment if it's never actually tested.
Keeping more than one copy in more than one place
A single backup location, even a reliable one, is still a single point of failure — a backup drive can fail at the same time as your main computer, or a cloud account can be locked out. Keeping at least two separate backup copies, ideally in genuinely different locations or systems, gives you a meaningfully better safety margin than relying on just one backup, however well-maintained that one backup is.
Setting a reminder rather than relying on memory
A backup routine that depends purely on remembering to do it tends to lapse over time, especially once the habit feels established and less urgent. A simple recurring calendar reminder, even a monthly one, is a low-effort way to keep the routine genuinely consistent rather than gradually drifting into irregular, ad hoc backups.
Frequently asked questions
Is one backup location enough, or do I need more?
Two genuinely separate locations is a reasonable, practical standard for most personal and small business needs; more locations add further protection but also more complexity to maintain.
Should I back up everything, or just the most important documents?
Prioritising genuinely important, hard-to-replace documents is a reasonable starting point if backing up everything feels overwhelming; expand from there as the routine becomes established.
How often should I update my backup?
As often as practical; automatic, continuous syncing removes the need to think about frequency at all, which is why it is the more reliable option where available.
Is a physical external drive better than a cloud backup?
Each has different trade-offs; a physical drive is not affected by an internet outage or account issue, while a cloud backup is protected against physical damage to your location. Using both provides the most comprehensive protection.
How do I know my backup is actually working?
Periodically test it by actually opening and using a file from the backup location, rather than assuming it is working without checking.
What if I have not backed up anything yet and it feels overwhelming to start?
Start with just your most important documents and build the habit gradually, rather than trying to back up everything at once.
Are the tools used to prepare documents for backup free?
Yes. No sign-up, no watermark, and files are removed from the server automatically about an hour after processing.
