Learn how to properly Delete Time Machine Backups on MacOS!

Optimizing your macOS experience goes beyond performance—it’s about mastering storage. In this guide, we will learn how to delete Time Machine backups on macOS.

Discover steps to free up disk space without compromising data integrity. Explore the intricacies of backup deletion, empowering you to streamline storage and enhance macOS efficiency.

As you manage your Time Machine backups, remember that this process isn’t just about reclaiming disk space. It’s about striking a harmonious balance between data protection and storage efficiency.

By following the outlined steps, you can selectively delete backups, systematically free up space, and tailor your backup strategy to suit your preferences.

What is Time Machine Backup on macOS?

Before delving into the deletion process, it’s crucial to understand how Time Machine works.

Time Machine creates incremental backups, preserving multiple versions of your files over time. These backups are stored on an external drive, a Time Capsule, or a network-attached storage (NAS) device.

Meanwhile, the backup process is automatic and usually requires minimal user intervention. However, it is essential to manage the storage space as backups accumulate over time.

1) Using System Preferences to Delete Time Machine Backups

Now, let’s explore the step-by-step process to delete Time Machine backups on macOS.

A) Open Time Machine Preferences

The first step is to access Time Machine preferences. Follow these steps.

• Click on the Apple logo in the top-left corner of your screen.

• Select “System Settings” from the drop-down menu.
• Click on “Time Machine” to open its preferences pane.

B) Select Backup Disk

In the Time Machine preferences pane, you’ll see a list of backup disks.

Select the disk you want to manage and click the “Options” button.

C) Exclude Items from Backup (Optional Step)

In the Options window, you can exclude specific items from future backups:

• Click the “+” button.
• Navigate to the items you want to exclude and add them to the exclusion list.

This step won’t delete existing backups but prevents those items from being included in future backups.

D) Delete Backups

To delete specific backups or entire backup snapshots, follow these steps.

To delete the entire Time Machine backup on a specific disk, try the steps below.

• Close the Time Machine preferences pane.
• Open a Finder window and navigate to the root level of your backup drive.
• Locate the “Backups.backupdb” folder. This folder contains all your Time Machine backups.
• Warning: Deleting items from this folder will permanently remove them from your backup. Ensure you’re deleting the correct backups.
• To delete the entire backup, you can move the “Backups.backupdb” folder to the Trash. Right-click on the folder and choose “Move to Trash” or press Command + Delete.

When you attempt to delete a backup, macOS will prompt you to enter your administrator password for confirmation. This adds an extra layer of security to prevent accidental deletion.

Method 2: Use Finder to Delete Time Machine Backups

Deleting Time Machine backups using Finder involves navigating to the root level of your backup drive and manually removing the backup snapshots.

However, it’s essential to approach this cautiously, as deleting the wrong files could result in data loss. Here are the steps.

A) Open Finder

Open a Finder window by clicking the Finder icon in your Dock or pressing Command + N to open a new Finder window.

B) Navigate to Backup Drive

Navigate to the root level of your Time Machine backup drive. This is the external drive where your Time Machine backups are stored.

Example:

• If your backup drive is named “BackupDrive,” you would typically find your backups in a folder named “Backups.backupdb” at the root level.

C) Locate Time Machine Backups

Inside the “Backups. backupdb” folder, you’ll see subfolders named with the date and time of each backup.

Example:

• Folders might be named like “2023-11-28-120000” representing the backup created on November 28, 2023, at 12:00:00 PM.

D) Select and Delete Specific Backups

To delete specific backups, select the folder corresponding to the date and time you want to remove.

Right-click on the selected folder and choose “Move to Trash” or Command + Delete.

E) Confirm Deletion

Confirm the action by clicking “Move to Trash” when prompted.

Method 3: Use Terminal to Delete Time Machine Backups

Follow these simple steps to delete old time machine snapshots using terminal.

Be careful while executing these commands. Furthermore, I recommend using the above two methods if you are not comfortable using terminal.

A) Open Terminal

1. Press Command + Space to open Spotlight Search.
2. Type “Terminal” and press Return to open the Terminal application.

B) Navigate to the Backup Drive

In the Terminal window, use the cd command to navigate to the root level of your backup drive. For example:

Verify that you are in the correct directory by using the ls command to list the contents of the current directory.

C) L ist Time Machine Snapshots

Use the tmutil command to list available Time Machine snapshots. The snapshots are identified by their date and time.

D) Delete Specific Backup Snapshot

Choose the specific backup snapshot you want to delete from the list generated in the previous step. Use the sudo tmutil deletelocalsnapshots

command followed by the path to the snapshot.

Replace “YourBackupDriveName” with the name of your Time Machine backup drive and “YourMacName” with the name of your Mac. Replace “YYYY-MM-DD-HHMMSS” with the specific date and time of the snapshot you want to delete.

E) Confirm and Verify Deletion

Terminal will ask for your administrator password to execute the sudo command. Enter your password and press Return.

Use the tmutil listbackups command again to verify that the specific backup snapshot has been deleted.

How to convert time machine drive to a normal drive?

Here is how to remove an external hard drive from time machine backup to use it as a normal drive.

1) Open Disk Utility

The first step is to open disk utility by either using:

• Spotlight Search
• Dock Utility

2) Navigate to External Hard Disk

Once you have opened the disk utility, click on the external hard drive name.

As you can see in the image, I have connected my hard drive and its name popped up in the disk utility.

3) Erase External Hard Drive

Now, left click on the external disk and select the “Erase” option from the dropdown menu.

After few moments, your time machine backup hard drive will revert back to Ordinary disk on which you can store regular files.

Reasons to Delete Time Machine Backups on macOS

You might consider deleting Time Machine backups on your Mac Devices for several reasons. These are as follows.

1) Storage Management

Time Machine backups can consume a significant amount of storage space over time. If you’re using an external drive for backups and running out of reach, deleting older backups can free up room for new ones.

2) Backup Drive Replacement

If you decide to change your backup drive (for example, upgrading to a larger capacity drive or replacing a malfunctioning one), you might want to start fresh on the new drive and remove the old backups from the previous drive.

3) Data Privacy and Security

Deleting backups becomes a security measure, particularly when disposing of or repurposing a drive.

It ensures that any sensitive or personal information stored in previous backups is inaccessible on the old backup drive.

If you have backed up confidential information that is no longer needed, deleting the backups is a prudent step to prevent unauthorized access.

4) Organizational Needs

Keeping unnecessary backups on your drive can clutter the storage space and make navigating through your backup history challenging.

Therefore, once in a while, you should de-clutter all the previous backups and delete the non-useful ones.

5) Performance Considerations

As the number of backups increases, creating new backups may slow down. Deleting old backups can contribute to a smoother and faster backup experience.

This might be one of the reasons why you are reading this article.
