In this step-by-step tutorial, we will help you clean up your disk and regain storage space on it by deleting old Time Machine backups.
How to delete old Time machine backups
Step 1: First off, you need to enter Time Machine by clicking the Time Machine icon in your Menu Bar.
Step 2: Next up, you have to navigate through the interface to the desired date.
Step 3: Here, you can click on the gear icon and select Delete Backup after locating the day you wish to delete from your backup
Step 4: Now, you will be required to confirm you really wish to delete the backup as well as you may be required to enter your administrator password. Finally, your device will delete the backup for that specific day once done.
How to remove old Time Machine backups using Finder
Step 1: First off, you need to click the desktop and select New Finder Window from the File menu, or press the Command (⌘)—N keys on your keyboard to open a new window.
Step 2: Then, you have to connect the disk containing your Time Machine backups to the computer and click on its name, which will appear underneath the Devices section in the Finder sidebar later.
If you want to continue, you have to enter your administrator name and password. You can also access the backup disk by entering a password in case you use AirPort Time Capsule.
Step 3: Now, you continue to navigate to the “Backups.backupdb” folder on your Time Machine backup disk as you would other folders. Make sure that, it is a top-level folder of your backup drive.
Step 4: Now, you have to navigate to the sub-folder called with your Mac computer’s name once inside the “Backups.backupdb” folder. For example, Time Machine will store backups inside the “iMac Retina” sub-folder in case your Mac is called “iMac Retina” in System Preferences.
Step 5: Here, a bunch of sub-folders will be appeared, each prefixed with the date of the backup in the YYYY-MM-DD format. You can also delete a desired backup sub-folder by right-clicking or Control (⌃)- clicking it and from the popup menu, you continue to choose Move to Trash.
This allows you to delete all copies of a backed-up file or folder from your Time Machine backup disk.
Step 6: Finally, you have to repeat the process for other full-day backups you want to remove. Once done, you can select the disk’s icon on the desktop to disconnect it, then, you simply need to choose Eject from Finder’s File menu.
