Preventing Accidental File Deletion and Making Backups

Why Backups Matter More Than You Think

Everyone knows they should back up their files, but most people don't until it's too late. Hard drives fail. Ransomware encrypts files. People accidentally delete entire folders. Windows Updates occasionally corrupt systems.

The question isn't whether you'll lose data—it's when, and whether you'll have a backup when it happens. Let's make sure you do.

Quick Fix: Enable File History Right Now

Windows has built-in backup called File History. It takes 5 minutes to set up:

1. Connect an external hard drive (or use a network drive)
2. Open Settings > Update & Security > Backup
3. Click Add a drive under "Back up using File History"
4. Select your external drive
5. Toggle Automatically back up my files to ON

That's it. Windows now backs up your Documents, Desktop, Downloads, Pictures, Videos, and Music every hour. If you accidentally delete something, you can restore previous versions.

Preventing Accidental Deletion

Before we talk about recovering files, let's prevent accidents in the first place.

Use the Recycle Bin Properly

The Recycle Bin is your first line of defense. When you delete a file, it goes to the Recycle Bin for 30 days (by default). To configure it:

1. Right-click Recycle Bin on desktop
2. Choose Properties
3. Set Maximum size to at least 5000 MB (5GB)
4. Ensure "Display delete confirmation dialog" is CHECKED

That confirmation dialog prevents accidental deletions when you press Delete.

Be Careful with Shift + Delete

When you press Shift + Delete, files bypass the Recycle Bin and are deleted immediately. Only use this when you're absolutely certain. If you have the habit of using Shift + Delete, stop—the Recycle Bin exists for a reason.

Enable "Show file extensions"

This prevents accidentally renaming files incorrectly:

1. Open File Explorer
2. Click View > Show > check File name extensions

Now you'll see "document.docx" instead of just "document," making it obvious what file type you're working with.

Setting Up File History (Complete Guide)

File History is Windows' automatic backup for your personal files. Here's how to configure it properly:

Step 1: Choose Your Backup Drive

You need an external drive or network location. Options:

• External USB hard drive: Cheapest option, 1-2TB drives cost $50-80
• Network drive (NAS): More expensive but backs up multiple PCs
• Second internal drive: Works but doesn't protect against theft or fire

Do NOT use the same drive where Windows is installed. If that drive fails, your backup is gone too.

Step 2: Enable File History

1. Connect your backup drive
2. Settings > Update & Security > Backup
3. Click Add a drive and select your backup drive

Step 3: Configure Backup Frequency

1. Click More options under File History
2. Set "Back up my files" to Every hour (or more frequently if you work on critical files)
3. Set "Keep my backups" to Until space is needed (or Forever if you have a large drive)

Step 4: Choose What to Back Up

By default, File History backs up:

• Desktop
• Documents
• Downloads
• Music
• Pictures
• Videos
• OneDrive (if synced locally)

To add folders:

1. In File History options, scroll down to "Back up these folders"
2. Click Add a folder and choose additional locations

To exclude folders (like Downloads if you don't need those backed up):

1. Scroll to "Exclude these folders"
2. Click Add a folder and select what to skip

Restoring Files from File History

When you need to recover a deleted or changed file:

Method 1: Previous Versions

1. Navigate to the folder that contained the file (or the file itself if it still exists)
2. Right-click and choose Restore previous versions
3. Select a version from before you deleted/changed it
4. Click Restore

Method 2: File History Interface

1. Type file history in Start menu
2. Click Restore your files with File History
3. Browse through backup snapshots using the arrows
4. Select the file you need and click the green Restore button

Cloud Backup: OneDrive

File History backs up locally. For protection against theft, fire, or complete PC failure, you also need cloud backup.

Setting Up OneDrive

Windows includes OneDrive with 5GB free (or 1TB with Microsoft 365):

1. Click the OneDrive cloud icon in the system tray
2. Sign in with your Microsoft account
3. Choose which folders to sync
4. Check Back up important folders to automatically backup Desktop, Documents, Pictures

Now your important files are protected both locally (File History) and in the cloud (OneDrive).

Alternatives to OneDrive

• Google Drive: 15GB free, works across platforms
• Dropbox: 2GB free, very reliable
• Backblaze: $99/year for unlimited backup, great for large libraries

The 3-2-1 Backup Rule

For critical files, follow this rule:

• 3 copies: Original + 2 backups
• 2 different media types: Internal drive, external drive, cloud
• 1 offsite copy: Cloud or drive at another location

Example setup:

1. Original files on your PC's SSD
2. File History backup to external USB drive
3. OneDrive or Google Drive for cloud copy

This protects against drive failure, theft, fire, ransomware, and user error.

Creating a System Image (Full PC Backup)

File History only backs up your files, not Windows itself or installed programs. For complete protection:

1. Connect a large external drive (needs space for your entire C: drive)
2. Type backup settings in Start
3. Scroll down and click Go to Backup and Restore (Windows 7)
4. Click Create a system image
5. Choose your backup drive and follow the wizard

System images let you restore your entire PC to a working state after catastrophic failure. Create one after you get Windows set up perfectly, then update it every few months.

Recovering Permanently Deleted Files

If you deleted something that bypassed the Recycle Bin, or emptied the Recycle Bin, you have options:

Check File History First

If File History was enabled, restore from there (see above).

Check OneDrive Recycle Bin

If the file was in OneDrive:

1. Go to onedrive.com
2. Click Recycle bin in the left sidebar
3. Files stay there for 30 days

Use File Recovery Software

If no backup exists, try recovery software IMMEDIATELY (the longer you wait, the more likely the file is overwritten):

• Windows File Recovery: Free from Microsoft Store, command-line based
• Recuva: Free, easier to use, good success rate
• EaseUS Data Recovery: Free for 2GB, professional features

Success isn't guaranteed, but it's worth trying.

Testing Your Backups

Having a backup isn't enough—you need to know it works. Every 3-6 months:

1. Open File History and try restoring a random file
2. Check that your external backup drive is still working
3. Verify OneDrive is actually syncing (check online at onedrive.com)
4. If you created a System Image, verify the file exists and isn't corrupted

A backup you've never tested is just wishful thinking.

What to Back Up (and What to Skip)

Always Back Up

• Documents, spreadsheets, presentations
• Photos and videos
• Email archives (PST files)
• Browser bookmarks and passwords
• Financial records and tax documents
• Creative projects (music, videos, designs)

Optional

• Downloads (usually replaceable)
• Temp files (waste of space)
• Installed programs (reinstall from internet)
• Windows itself (unless doing System Image)
