How to Delete Time Machine Backups & Snapshots on Mac (2026 Full Guide)

Part 1. When and Why You Should Delete Time Machine Backups on Mac

Time Machine is designed to manage backups automatically, but there are situations where manual cleanup becomes necessary. Understanding the right timing and reasons helps avoid accidental data loss.

1. Is It Safe to Delete Old Time Machine Backups?

Yes, it is safe to delete old Time Machine backups in most cases. Time Machine creates backups over time, keeping older versions of your files so you can restore them if needed. When you delete old backups, you are only removing those older versions, not your current files or system.

What happens after deleting old backups:

• You won't be able to restore very old versions of files
• Your latest backup stays safe
• Time Machine will continue creating new backups normally

Your data remains protected as long as you keep at least one recent backup.

2. Benefits of Removing Old Backups

Deleting old Time Machine backups provides several benefits:

• Free up valuable disk space on your external Time Machine drive or internal Mac storage
• Prevent backup failures caused by a full or nearly full backup disk
• Improve Time Machine performance, allowing backups to complete faster
• Reduce system clutter and junk by eliminating outdated and unnecessary backup versions
• Avoid storage warnings such as "Your Time Machine disk is almost full".
• Make backup management easier, so important restore points are easier to identify

Regularly deleting old backups from Time Machine helps maintain a healthy backup system while keeping your Mac running smoothly.

3. Which Backups Should I Keep?

Follow these best practices when deciding which backups to keep to stay protected while still reclaiming storage:

• Always keep at least one recent full backup
• Keep backups created before major macOS updates
• Retain backups that include important projects or personal data
• Delete very old backups that you know you'll never need
• Remove backups from Macs you no longer use or recognize.

This balanced approach ensures you can safely clear Time Machine backups without compromising data security.

Part 2. How to Delete Time Machine Local Snapshots on Mac

Local snapshots are temporary backups stored on your Mac when your Time Machine drive isn't connected. They can silently take up a lot of storage. The following methods help you safely remove them and free up space.

1. Disable & Re-enable Automatic Backups in Time Machine Settings

The easiest way to remove Time Machine local snapshots is by restarting the backup service. Turning the Time Machine off and back on forces macOS to automatically clear unnecessary local snapshots without using Terminal or advanced tools.

Steps:

• Click the top-left Apple logo, then open "System Settings".

• Open "General", then open "Time Machine".

• Toggle off or uncheck "Back Up Automatically" the box (or set Backup Frequency to Manually in Ventura or later).



• Wait 5 to 10 minutes so macOS can clear local snapshots in the background.

• Turn "Back Up Automatically" back on.

Note:

This doesn't always remove all snapshots immediately, especially if disk pressure is low.

2. Delete Specific or Old Snapshots Using Disk Utility

Disk Utility allows you to view storage usage and, in some macOS versions, manage APFS snapshots. While it doesn't always allow direct deletion, it helps identify snapshot-related space usage and confirm whether snapshots exist on your Mac.

Steps:

• Open "Disk Utility" from Applications > Utilities.

• Select your main volume such as "Macintosh HD" from the sidebar.

• From the menu bar, choose "View" > "Show APFS Snapshots" to display all volumes and snapshots.



• Select the snapshots you want to remove (hold Command for multiple).

• Then click the Delete button (minus sign –) in the toolbar, or right-click and choose "Delete APFS Snapshot".

• Confirm the deletion when prompted by clicking "Delete".

• Restart your Mac to allow macOS to remove unnecessary local snapshots.

This method works best when disk space is constrained.

3. Delete Time Machine Snapshots in Terminal

Using Terminal is the most reliable and effective way to delete Time Machine local snapshots. This method gives you full control to remove specific snapshots and instantly free up disk space when other options don't work.

Steps:

• Open "Terminal" from Applications, then Utilities.

• List all local snapshots by typing: tmutil listlocalsnapshots /

• Note the snapshot date you want to remove.

• Delete the snapshot using: sudo tmutil deletelocalsnapshots YYYY-MM-DD-HHMMSS (e.g., sudo tmutil deletelocalsnapshots 2026-01-30-123456).



• Enter your administrator password and wait for confirmation.

Warning:

Deleted snapshots cannot be recovered once removed.

Part 3. How to Delete Time Machine Backups from External Hard Drive

If your Time Machine backup disk is full, you'll need to remove old backups manually. Below are three proven methods.

1. Manually Delete Old Backups via Time Machine Interface

Using the Time Machine interface is the safest and most Apple-recommended way to erase a Time Machine backup. This method lets you delete specific backups directly from Time Machine while preserving the integrity of your external backup drive.

Steps: Steps:

• Connect your Time Machine external hard drive to your Mac.

• Select the "Time Machine" icon from the menu bar and choose "Enter Time Machine".



• Go to the "backup data" you want to delete.

• Click the gear icon (⋯) or "Action menu".

• Choose "Delete Backup" and confirm.

2. Remove Time Machine Backups Using Finder

Finder gives you direct access to your backup drive, allowing you to clear Time Machine backups manually. This method works well when Time Machine won't load properly but you still need to remove old backups from Time Machine to free storage.

• Plug in your Time Machine backup drive.

• Open "Finder" and select the external drive.

• Select the backup drive from the sidebar.

• Open the "Backups.backupdb" folder.



• Open the folder named after your Mac.

• Right-click the dated backup you want to remove.

• Select "Move to Trash", then empty "Trash".

Note:

You may be asked to enter your administrator password to erase a Time Machine backup.

3. Delete Old Time Machine Backups Using Terminal

Terminal offers the most powerful way to delete old Time Machine backups, especially when Finder or Time Machine fails. This advanced method is ideal for users who need full control when safely deleting old backups from Time Machine.

Steps:

• Connect your Time Machine backup disk.

• Open Terminal from "Applications", then "Utilities".

• List all backups by typing: tmutil listbackups.

• Copy the full path of the backup you want to remove.

• Run the command: sudo tmutil delete /path/to/backup (e.g., sudo tmutil delete /Volumes/YourDriveName/Backups.backupdb/YourMacName/2025-01-01-120000).



• Enter your "Mac password" and wait for completion.

Warning:

This action permanently removes the selected backup and cannot be undone.
