What Is PC Backup and How Do You Back Up Your Computer?
Updated
PC backup means keeping a second copy of your important files somewhere other than the drive they normally live on, so you can restore them if the original is lost, corrupted, or deleted. On Windows, the simplest reliable routine is: pick the folders that matter, copy them to a separate destination (external drive, NAS, or cloud folder), let a tool repeat that copy automatically on a schedule, and then confirm you can actually restore a file. FolderClone is one example of a Windows tool built around this "set it and forget it" copy-and-sync approach, and it offers a 30-day free trial per the vendor's site.
What "backup" actually means here
People use "backup" loosely, but three different things get called by that name, and they behave differently when you need to recover.
| Approach | What it does | Good for | Limitation |
|---|---|---|---|
| Full copy | Makes a one-time duplicate of files to another location | Archiving a snapshot, moving data to a new drive | Goes stale the moment you change a file |
| Synchronization | Keeps the target folder matching the source, updating new and changed files | Ongoing protection of working files with minimal effort | A deletion or corruption can propagate to the copy |
| Versioned backup | Stores multiple historical versions of each file | Recovering from accidental edits, ransomware, or bad saves | Uses more space; needs software that supports versions |
FolderClone sits in the synchronization category. Per the vendor, it "lets you make an identical copy of a folder from one drive to another" and "runs in the background, periodically checking the source folder and updating the target folder with new or changed files." That makes it strong for keeping a live duplicate, but it is not a versioned archive — if you need to roll back to last Tuesday's version of a file, you need a tool that keeps history.
Decide what to back up
You do not have to choose between "everything" and "nothing." Match the scope to how much you'd suffer losing it.
- Important folders — documents, photos, project files, financial records. This is the highest-value, lowest-effort target and where most people should start.
- Entire drive — useful when you want a complete duplicate of a data drive, but it includes junk you don't need and takes longer.
- System image — a full snapshot that can restore Windows itself, not just files. This is a different job from file backup and usually needs separate tooling.
FolderClone's model is folder-to-folder: you point it at a source folder and a target folder. That fits the "important folders" case directly, and it can also replicate between machines — the vendor notes it can "copy files between a desktop computer and a laptop, or replicate data between a workstation and a server."
Pick a destination
The copy has to live somewhere the original failure can't reach.
- External drive — fast, cheap, works offline. Keep it disconnected between runs if you want protection from ransomware and surges.
- NAS — good for multiple computers on one network, always available, but it's still on-site.
- Cloud storage — off-site protection. FolderClone's site states it can copy files "to cloud storage providers such as OneDrive, Google Drive, etc.," typically by syncing to a local folder that the cloud client then uploads.
A practical pattern is two destinations: a local external drive for fast, frequent restores, plus a cloud or off-site copy for the disaster case. One copy is a single point of failure.
Set up an automatic schedule
The whole point of automation is that you stop thinking about it. The general flow with a sync tool like FolderClone:
- Install and open the tool. FolderClone offers a 30-day free trial; the site lists Download and Purchase options, so treat continued use beyond the trial as a paid decision rather than assuming it's free.
- Create a task or job and set the source folder — the one holding your important files.
- Set the target folder — the external drive, NAS share, or cloud-synced folder.
- Choose the schedule. "Periodically" is the vendor's wording; pick an interval that matches how often your files change (hourly for active work, daily for most people).
- Run it once manually and watch it complete, so you catch permission or path errors before trusting it unattended.
- Leave it running in the background. FolderClone is designed to check the source and update the target without further input.
The vendor frames the payoff plainly: "if something ever happens to your source files, the program can easily restore them from the copies on the target folder." A user quoted on the site, R. Kilburn, described a server failure where the machine receiving FolderClone's copies "merely needed its name changed on the network and immediately became my server" — a real example of a synchronized copy doubling as a replacement.
Verify the backup and test a restore
An unverified backup is a guess. Do this once, then spot-check occasionally.
- Compare counts and sizes. Confirm the target folder holds the files you expect, not an empty or partial copy.
- Restore a real file. Delete or rename one unimportant file in the source, then restore it from the target. If you can't get it back, the backup isn't working.
- Check the log or status. Most tools report the last run time and any errors. A job that silently stopped three weeks ago is worse than no job, because you think you're covered.
- Re-test after changes. New drive letters, renamed folders, or a moved NAS can break a scheduled task without obvious warning.
Common sticking points
- Sync isn't versioning. If a file is corrupted or deleted at the source, a pure sync can mirror that loss. Keep a versioned or offline copy for anything irreplaceable.
- Cloud folders need the client running. Copying into a OneDrive or Google Drive folder only reaches the cloud if that app is signed in and syncing.
- Permissions and locked files. System folders and open files may be skipped; back up user data rather than trying to grab everything.
- The trial is a trial. FolderClone's free period is 30 days; plan for the purchase decision if you keep using it.
The short version: define your important folders, send copies to at least one separate location, automate the copy so it runs without you, and prove you can restore before you need to.
