Before You Move or Delete That File: Understand Sync and Backup

10 August, 2026

FILE BASICS

Your files may look like they are all in one place. They are not.

A file may live on your computer, in OneDrive, in Google Drive, or in SharePoint. It may also appear in several places at once because it is being synced.

Common questions

Where is this file actually stored?

If I delete it here, does it disappear everywhere?

Is sync the same as backup?

Four ideas make the rest much easier

These terms often get mixed together, but each one does a different job.

Storage

Where the file lives.

Sync

Keeps connected files up to date.

Recovery

Helps get deleted or changed files back.

Backup

Adds another layer of protection.

Where your files can live

Your computer

Files may live in Desktop, Documents, Downloads, Pictures, or other local folders.

But some of these folders may also be connected to cloud storage.

OneDrive & Google Drive

Personal cloud storage for files you want to open, share, or use across different devices.

Cloud storage is not the same as backup.

SharePoint

Shared files for teams, departments, labs, projects, and Microsoft Teams channels.

A file here may matter to many people, not just you.

Sync means changes travel with the file

Think of synced files as connected. If you change something in one place, that change is designed to appear in the other.

Create

The new file can appear elsewhere.

Edit

Changes can appear on other devices.

Rename

The new name can appear everywhere.

Delete

The deletion can also sync.

Sync does not create a separate safety copy.

When cloud files show up on your computer

OneDrive, Google Drive, and SharePoint can all make cloud files appear inside File Explorer on Windows or Finder on macOS.

They may look local, but if they are synced, changes made on your computer can also affect the cloud version.

Seeing a file on your computer does not mean it exists only there.

Take extra care with SharePoint

SharePoint files often belong to a team. You may connect a whole document library, a specific folder, or several SharePoint locations to your computer.

If you delete a synced SharePoint file from File Explorer or Finder, the deletion can also be sent back to SharePoint and affect everyone using that location.

Before deleting, ask: Do I no longer need this file, or does the team no longer need this file?

Avoid connecting the same SharePoint files twice

Problems can happen when the same SharePoint content is connected in more than one way.

Avoid connecting a specific folder and then also connecting the larger library that contains it. Also avoid adding a OneDrive shortcut to content that is already connected another way.

One method per SharePoint location

Working on more than one computer

OneDrive and Google Drive can keep the same files available across several computers.

That means you can work on a desktop in your office, then continue from your laptop without copying files back and forth yourself.

Connected files stay in sync. They are not separate backup copies.

Not everything you see is a real folder

Some areas in File Explorer and Finder simply help you find files faster.

Recents Recent Files Quick Access Favorites Search Results

These views usually point to the original file. Deleting something from Recents, for example, may delete the real file wherever it is stored.

If you delete something by mistake

OneDrive

Deleted files usually go to the Recycle Bin.

Normally kept for up to 93 days.

Google Drive

Deleted files go to Trash.

Normally kept for 30 days.

SharePoint

Files first go to the Recycle Bin, then may move to the second-stage Recycle Bin.

Total retention is normally 93 days from the original deletion.

Where Atempo Lina fits

Atempo Lina is KAUST's backup service for files stored locally on your computer.

OneDrive, Google Drive, and SharePoint focus on cloud storage and sync. Lina protects selected local folders so they can be restored if something goes wrong.

Installed does not mean protected

You still need to choose which local folders Lina should back up.

General rule: use Lina for important files that stay local to your computer. Files already synced with OneDrive, Google Drive, or SharePoint usually do not need to be added again.

A quick way to decide

Mainly for me?

Use OneDrive or Google Drive.

For a team?

Use the appropriate shared location, such as SharePoint.

Need it on several computers?

Use sync.

Only on this computer?

Consider protecting it with Atempo Lina.

The key thing to remember

A file appearing in File Explorer or Finder does not necessarily mean it exists only on your computer.

Before moving, renaming, or deleting a file, know where it really lives.
