How to back up your files before a repair (or before anything goes wrong)

Nobody thinks about backing up until the moment they wish they had. A machine starts misbehaving, or a repair is booked in, and suddenly the worry is not the computer at all, it is the ten years of photos and the documents that live nowhere else.

Here is the reassuring part first: for most repairs your files are never in danger, and any careful technician guards your data as the most important thing on the machine. But a backup means you never have to depend on that, and it takes far less time than most people expect. This guide walks through how to do it simply, whether you are handing a machine in or just being sensible before something goes wrong.

Why back up before a repair

Most repairs do not touch your files. A screen, a battery, a charging port, a memory top-up: none of these go near your photos. So why bother?

Because a few jobs do carry risk, and because a backup costs you almost nothing to have and everything to lack. A failing drive that has to be worked on, a serious infection, or a full Windows reinstall all involve the part of the machine your files live on. And no honest technician will ever promise a perfect outcome on a drive that is already unwell, because the drive may not survive being read. A backup turns “I hope this goes smoothly” into “it does not matter if it does not”.

There is a wider point too. A drive can fail with no warning at all, a laptop can be lost or stolen, and a spilled drink does not check whether you backed up first. The habit that protects you before a repair is the same habit that protects you every other day.

What to back up first

If you did nothing else, do this: back up the things money cannot buy back first, because Windows and your programs can always be reinstalled, and your photographs cannot.

Work in this order of priority:

1. Photos and videos. The single most irreplaceable thing on most people’s machines. Start here.
2. Documents you have made. Letters, spreadsheets, that thing you have been writing, anything you created rather than downloaded.
3. Financial and official records. Tax paperwork, statements, receipts, anything you might need to prove or refer back to.
4. Work files. Anything job-related that exists only on this machine.
5. Everything else, if there is time. Downloads, installers and programs come last, because they can nearly always be fetched again.

The reason for the order is simple. If time or the machine runs out halfway through, you will have saved the things that truly matter and lost only the things you can replace.

Where to put the backup

A backup has to live somewhere separate from the computer, because a copy on the same machine is no protection if that machine is the problem. You have three good options:

• An external hard drive. The workhorse for a full backup. Plenty of room for everything, quick to copy to and quick to restore from later. Keep it somewhere safe once done.
• A USB memory stick. Perfect for the small, precious stuff, the folder of photos and key documents, when you do not need to copy the whole machine. Cheap and pocket-sized.
• Cloud storage. A copy kept safely online, which survives anything happening to your home or your hardware. Slower for very large amounts, and it depends on your internet, but wonderfully safe.

The strongest approach is not choosing between them but doubling up: a local copy on a drive for speed, and a cloud copy for safety. Two copies in two places is what turns a backup from “probably fine” into “genuinely safe”.

How to actually copy it across

You do not need special software for a basic backup. The everyday way works.

• Plug in your external drive or USB stick.
• Open your files, and find your main folders: your Pictures, your Documents, your Desktop, and anywhere else you keep things.
• Select what you want, then copy it, and paste it onto the external drive. Dragging the folders across does the same job.
• Wait for it to finish properly. A big folder of photos can take a while, and pulling the drive out early leaves you with a half-copied, useless backup.

Then the step everyone skips and nobody should: open the backup and check it. A backup you have not opened is a hope, not a backup. Browse into the copied folders on the drive, open a photo, open a document, and make sure they are really there and really work. It takes two minutes and it is the difference between a backup and a false sense of security.

If the machine will barely start

This is where care matters most, because the wrong move can turn a recoverable situation into a lost one.

If the computer is slow and struggling because the drive is failing, every extra hour of use is wear it cannot afford. If it does start, copy the small irreplaceable things first, quickly, while you still can, and do not sit it through a marathon copy of everything. And if the drive is making mechanical noises, clicking, grinding or repeatedly spinning up and down, stop. Power it down and get help, because heavy copying can be the thing that finishes a dying drive.

This is exactly the judgement call where a quick conversation helps, and the diagnosis is always free. If the files really matter and the machine is unwell, it is better to let someone recover them properly than to risk them chasing a backup that the drive may not survive.

The honest bottom line

A backup is the cheapest insurance in computing, and the only one you can take out yourself in half an hour.

Do it before a repair, and you hand the machine over with nothing to fear. Do it as a habit, and a failed drive or a stolen laptop becomes an inconvenience instead of a heartbreak. And if the worst has already happened, the machine will not start and there was no backup, that is what data recovery is for. We will tell you honestly what is realistic, the diagnosis costs nothing, and if we cannot get your files back there is nothing to pay. That is no fix, no fee, applied to the thing you actually care about.
