AvatarByHarold Trujillo Apple Devices & MacOS

Backing up your MacBook is an essential practice to safeguard your valuable data, but over time, these backups can accumulate and consume significant storage space. Whether you’re running low on disk space or simply want to tidy up old backups that are no longer needed, knowing how to delete backups on your MacBook can help you maintain optimal performance and organization. Understanding the process ensures you manage your storage efficiently without risking the loss of important files.

Many Mac users rely on Time Machine or other backup solutions to protect their data, but these backups can sometimes become outdated or redundant. Deleting backups thoughtfully allows you to reclaim precious disk space and keep your system running smoothly. However, it’s important to approach this task with care to avoid accidentally removing backups that you might need later.

In the following sections, we’ll explore the different types of backups stored on your MacBook and outline safe, effective methods to delete them. Whether you’re a casual user or a tech-savvy individual, this guide will equip you with the knowledge to manage your backups confidently and keep your MacBook’s storage in check.

Deleting Time Machine Backups

To delete backups created by Time Machine on your MacBook, you need to access the backup storage and remove the unwanted backup files. Time Machine stores its backups on an external drive or a network-attached storage (NAS) device. Deleting backups manually requires caution to avoid corrupting the backup history.

To safely delete Time Machine backups:

  • Connect the Time Machine backup drive to your MacBook.
  • Open Finder and navigate to the backup drive.
  • Locate the folder named Backups.backupdb.
  • Inside this folder, you will find subfolders named by your Mac’s hostname.
  • Open the folder and identify the backup dates you wish to delete.
  • Instead of deleting files manually, use the Time Machine interface or Terminal commands to ensure backup integrity.

Using the Time Machine interface:

  • Click the Time Machine icon in the menu bar and select Enter Time Machine.
  • Navigate to the date of the backup you want to delete.
  • Right-click on the backup and select Delete Backup.
  • Enter your administrator password to confirm.

Alternatively, you can use Terminal commands for deleting backups with administrator rights:

“`bash
sudo tmutil delete /Volumes/YourBackupDrive/Backups.backupdb/YourMacName/YYYY-MM-DD-HHMMSS
“`

Replace `YourBackupDrive`, `YourMacName`, and the date/time string with appropriate values.

Removing iCloud Backups on MacBook

If you use iCloud to back up your iOS devices or store data, you may want to manage or delete these backups to free up iCloud storage. Managing iCloud backups on a MacBook involves accessing system settings and iCloud preferences.

To delete iCloud backups from your MacBook:

  • Open System Settings (or System Preferences on older macOS versions).
  • Click on your Apple ID at the top.
  • Select iCloud from the sidebar.
  • Click Manage next to iCloud storage.
  • Choose Backups from the list of apps using storage.
  • Select the device backup you want to delete.
  • Click Delete Backup and confirm.

This process removes the backup from iCloud, freeing storage space but does not affect the data on the device itself.

Deleting Local Snapshots of Backups

macOS automatically creates local snapshots of Time Machine backups on your internal drive when the backup disk is unavailable. These snapshots can consume significant disk space over time.

To delete local snapshots manually:

  • Open Terminal.
  • List all local snapshots using:

“`bash
tmutil listlocalsnapshots /
“`

  • Delete specific snapshots with:

“`bash
sudo tmutil deletelocalsnapshots
“`

Replace `` with the snapshot identifier from the list.

Note that macOS also automatically manages these snapshots, deleting older ones as space is needed.

Comparison of Backup Deletion Methods

Backup Type Deletion Method Effect Requirements
Time Machine Backups Time Machine interface or Terminal (tmutil delete) Removes selected backup snapshots from external drive Backup drive connected, admin rights for Terminal
iCloud Backups System Settings > Apple ID > iCloud > Manage > Backups Deletes device backups stored in iCloud Apple ID credentials
Local Snapshots Terminal command (tmutil deletelocalsnapshots) Frees up internal disk space by deleting local snapshots Admin rights, Terminal access

Precautions When Deleting Backups

Deleting backup files can lead to permanent data loss if done incorrectly. Always consider these precautions:

  • Verify that the backup you are deleting is no longer needed.
  • Avoid manually deleting backup files in Finder without using Time Machine or Terminal tools.
  • Ensure you have an alternative backup before deleting any backups.
  • Use administrator privileges responsibly to avoid system damage.
  • For iCloud backups, understand that deleting a backup only removes stored data on iCloud and does not impact the device’s current data.

By following these guidelines, you can safely manage and delete backups on your MacBook to optimize storage space.

Deleting Time Machine Backups on Your MacBook

Time Machine is the default backup system on macOS, automatically creating backups of your files and system data. Over time, these backups can consume significant disk space, prompting users to delete older or unwanted backups. The process for deleting Time Machine backups depends on whether the backups are stored on an external drive or the local snapshot on your MacBook’s internal storage.

To safely delete Time Machine backups, follow these steps carefully to avoid corrupting backup data or losing essential files.

Deleting Backups Stored on an External Drive

If your Time Machine backups reside on an external hard drive or network-attached storage (NAS), use the following method:

  • Connect the Backup Drive: Ensure the external backup drive is connected and mounted on your MacBook.
  • Enter Time Machine: Click the Time Machine icon in the menu bar and select “Enter Time Machine.”
  • Locate the Backup to Delete: Navigate through the timeline to find the specific backup snapshot you want to remove.
  • Delete the Backup: Right-click (or Control-click) on the backup folder or file and select “Delete Backup.” You may be prompted to enter your administrator password.
  • Confirm Deletion: Confirm the deletion when prompted. Time Machine will safely remove the selected backup from the drive.

Note that direct manual deletion of Time Machine backups via Finder is not recommended, as it can cause backup corruption.

Removing Local Snapshots on MacBook Internal Storage

macOS also creates local snapshots of your backups on your internal drive when the external Time Machine disk is unavailable. These snapshots can occupy substantial disk space but are automatically managed by the system. To manually delete these local snapshots, use Terminal commands:

Command Description
tmutil listlocalsnapshots / Lists all local Time Machine snapshots on the startup disk.
sudo tmutil deletelocalsnapshots <snapshot_date> Deletes a specific local snapshot by its date (format: YYYY-MM-DD-HHMMSS). 
Example sequence:
tmutil listlocalsnapshots /
sudo tmutil deletelocalsnapshots 2024-06-15-123456

Be sure to replace <snapshot_date> with the exact timestamp of the snapshot you wish to remove. Administrator privileges are required to execute the deletion command.

Freeing Up Space by Deleting Backups from iCloud

If your backup includes iCloud data or you use iCloud Drive for backups, managing storage is different:

  • Open System Settings (or System Preferences on older macOS versions).
  • Go to Apple ID > iCloud > Manage or Manage Storage.
  • Select Backups in the list of applications using iCloud storage.
  • Choose the device backup you want to delete and click Delete Backup.
  • Confirm your choice to permanently remove the backup from iCloud.

This process helps reclaim iCloud storage space but does not affect local Time Machine backups on your MacBook or external drives.

Best Practices When Deleting Backups

  • Verify Backup Importance: Always confirm that the backup you intend to delete is no longer needed to avoid accidental data loss.
  • Use Time Machine Interface or Terminal: Avoid deleting backup files directly through Finder or other file management tools.
  • Maintain Regular Backups: Ensure you have a current backup before deleting older ones to safeguard your data.
  • Check Available Storage: Use About This Mac > Storage to monitor free space before and after deletion.
