How to move an old computer's files to the cloud

Moving files from an old computer to Google Drive, OneDrive or iCloud is simple but easy to get wrong. Here is how to do it carefully and check the result.

Putting your old computer's files in the cloud is a sensible step. It protects you if the machine fails, and it makes photos and documents reachable from your phone. But it is also easy to start in the wrong way, with half-uploaded folders, a full storage plan, or a computer that is too slow to finish the job.

Here is a calm approach.

Step 1: Choose the right service for your family

  • Google Drive and Google Photos work well if the family already uses Gmail and Android.
  • OneDrive is a natural fit for Windows and Microsoft 365 users.
  • iCloud suits families with iPhones and Macs.

There is no single best choice. Pick the one that the person who will look after it can actually manage. Make sure the account belongs to you, uses a strong password, has two-step verification on, and has recovery details that still work.

Step 2: Check how much space you need

Right-click the folders you want to upload and look at their total size. Then check how much room you have in your plan. Free plans are small, and the space is shared across email, documents and photos. If you need more, a paid plan may be worth it, but remember it is an ongoing cost. Prices and storage limits change, so check the current offers on the provider's own site.

Step 3: Tidy only a little first

You do not need to sort everything before uploading. But do remove obvious junk such as installer files and temporary folders. If the machine is old, do not run a big clean-up that deletes files you might need. When in doubt, keep it.

Step 4: Make sure the connection is reliable

Uploading tens of gigabytes can take many hours or even days on a typical home connection. To avoid trouble:

  • Use a wired or strong Wi-Fi connection, and do not rely on mobile data unless you have a generous plan.
  • Plug the computer into a stable power supply, ideally with a UPS.
  • Turn off sleep mode so the upload is not interrupted.
  • Start with the most important folders so that, if the old computer fails, the vital things are already safe.

Step 5: Upload in a sensible way

You can use the provider's desktop app, which syncs a chosen folder, or upload through the browser. For a large first upload, the desktop app is usually more dependable, because it can resume after interruptions. If the old computer cannot run a modern app, copy the files first to an external drive and upload from a newer computer.

Be careful with "sync" folders. If you move a folder into the cloud folder and later delete it from the computer, the cloud copy may be removed too. Use copy rather than move, and keep the original until you have verified the upload.

Step 6: Check that everything arrived

  1. Wait until the upload shows as finished, with no errors or paused files.
  2. Sign in on a different device, such as your phone or another computer, and look at the folders.
  3. Compare the number of files and the total size with the original folders.
  4. Open a sample of photos, documents and videos from the cloud, not from your computer.
  5. Look for any "could not upload" messages. Long file names and unusual characters can cause failures.

The cloud is one copy, not the whole plan

A cloud copy is excellent, but it should not be the only one. If the account is locked, or storage runs out and uploads quietly stop, you could be exposed. Think about the simple 3-2-1 idea: three copies, on two kinds of storage, with one somewhere else. The cloud can be the "somewhere else". Keep another copy on a drive you own.

A note on privacy

Once your files are in the cloud, they sit on a company's servers. For most family files this is fine, but think about very sensitive documents. You can keep those in an encrypted folder, or on an offline drive only.

If you would rather not do it yourself

If the old computer is slow, the upload keeps failing, or there are several computers involved, you may prefer help. Our risk assessment is a good starting point, or contact us directly.

Questions

Short answers.

How long will it take to upload my files to the cloud?

It depends on the amount of data and your internet speed. Tens of gigabytes can take many hours or days on a home connection, so start with the most important folders and let the upload run uninterrupted.

Can I delete the files from my computer after uploading?

Only after you have checked the cloud copy from another device, and ideally made a second copy elsewhere. Be careful with sync folders, where deleting locally can delete in the cloud.

Which cloud service should I use?

Choose the one your family can manage easily: Google for Gmail and Android users, OneDrive for Windows users, iCloud for Apple users. Secure the account with two-step verification and keep recovery details updated.
