Why Time Machine Backups are Stored in External Storage Not Internal?

For most purposes, backups from the Time machine are typically not saved on the Mac’s internal drive. Rather, they are kept on an external drive, network drive, or a Time Capsule. This is done for a few reasons:

  • Avoiding Information Destruction: In the event of an internal hard drive being faulty, it would be pointless to keep any backups on that same hard drive. Backing up data to a different and external storage device means even when the primary hard disk fails, you still have backups intact.
  • Available Memory: Time Machine saves very many backups over time, and that is quite a lot of space used up. Should the internal hard drive be utilized in that manner, it would not be long before the space runs out, which would in turn lower the operational efficiency of the computer.
  • Concentrated Backup Maintenance: Any information stored in the backups does not interfere with how the internal drive operates. Therefore, the user can better control how full the backups are by removing the backup storage device, removing the backup storage device and replacing it, and so on.

Nonetheless, there is a functionality present in macOS known as local snapshots, which saves temporary copies of backups to the internal hard disk only when the external Time Machine drives are not available. This feature offers the additional benefit of keeping the internal storage free, although the recovery files are still kept, but they are cleaned up periodically when space becomes a necessity.

How to Delete Time Machine Backups?

Several methods can be used to delete Time Machine backups. We will discuss them accordingly with their respective step-by-step guide.

1. How to Delete Backups on Time Machine​ Using the Instant Solution

sudo tmutil deletelocalsnapshots /

Step 5. You will be prompted to provide your password for verification before proceeding.

This method is useful when you have all the local snapshots stored in your Mac’s internal storage system.

5. Disable and Delete Local Snapshots in Mac

If you prefer not to manage local snapshots at all, you can disable them to stop macOS from creating future local backups. Here are the steps to perform:

Step 1.  Again, launch the Terminal app from Applications > Utilities.

Step 2. Use the following command to turn off local snapshots:

sudo tmutil disablelocal

Step 3. If you want to turn the feature back on later, use:

sudo tmutil enablelocal

This option is useful if you don’t need local snapshots and want to free up space by preventing them from being created.

6. How to Delete Time Machine Backups via Disk Utility

If you want to erase all the drive backups, you can use Disk Utility to wipe the disk on which your Time Machine backs up all data. Let’s observe the steps:

Step 1. Click Applications → Utilities → Disk Utility.

Step 2. In the left panel, choose the external disk you configured for the Time Machine backups.

Step 3. At the Erase window’s upper section, click on the Erase icon. A window will launch requesting the desired format and name for the drive. Select a format such as APFS or Mac OS Extended (Journaled) based on your choice.

Step 4. Click on the Erase button to finish the task. This action will erase all the data or backups that are contained in the external hard drive.
