Most repairs — a new battery, a thermal paste change, a GPU swap — never go near your files. But any job involving storage, the operating system, or a computer that's already misbehaving carries some risk. A ten-minute backup removes it.
1. Find what actually matters
Ask yourself what you'd be upset to lose. For most people it's:
- Photos and videos (often in Pictures, Desktop, or a phone-sync folder)
- Documents — school work, taxes, business files
- Anything on the Desktop — people keep a surprising amount there
- Game saves that aren't synced to the cloud
Programs themselves don't need backing up; they can be reinstalled.
2. Copy it somewhere else
Pick whichever is easiest:
- An external drive or USB stick. Drag the folders across. Simple and fast.
- Cloud storage — OneDrive, iCloud, Google Drive. Check that it has actually finished syncing before you hand over the computer.
3. Check the copy
Open two or three files from the backup — a photo, a document. A backup you haven't checked is a guess.
4. Write down what you'll need afterward
Make a short list of the things that are annoying to set up again: Wi-Fi password, email accounts, software license keys, and where your important files live. Keep passwords in a password manager, not a sticky note in the box.
5. Tell the technician
Mention if there's something especially important on the machine, or if you'd rather it isn't accessed beyond what the repair needs. A good shop will note that on the intake form.
No time, or not sure you got everything? A pre-service data backup can be added to any job.
