If you’re using a Mac, backing up your files is essential for peace of mind. With macOS’ built-in Time Machine, you can back up system files and apps, as well as your personal data, including music, photos, movies, emails, documents and more. This backup process is automatic and keeps multiple copies of your files, so you can always recover a file from an earlier point in time.
This is an excellent way to save all your data and prevent it from being lost in case of a crash or other problem with your computer. However, some users have reported that they can’t use their external hard drive for Time Machine backups, which is a bit frustrating. There are several solutions to this issue, but the most effective one is to clean your hard drive using a tool like Disk Utility. If this doesn’t help, you can also try reinstalling macOS or turning off the feature in the system preferences menu.
To get started, connect your external hard drive to your Mac. Open Finder and select the drive from the sidebar on the left. Right-click and click on “Get Info”. If the drive hasn’t been partitioned, you can do so in the Disk Utility application. If the drive has already been partitioned, make sure to create a partition that is at least 2-3 times larger than your Mac data.
Once the partition is created, you can start using the drive for Time Machine backups. You can check the status of your backups by clicking on the Time Machine icon in the menu bar or clicking on “Enter Time Machine” when you’re using your Mac. If you’re using the drive for other purposes, you can uncheck the option to show Time Machine in the menu bar.
If you want to change the default destination for your backups, click on the Options button in the Time Machine preference pane and select a new location. In the same pane, you can choose to exclude specific folders and applications from your backups.
When you need to restore a file from the backup, click on the Restore button in the menu bar or click on “Enter Time Machine” when you’re on your Mac. You will be asked to choose the disk where you want to restore the file and then confirm the selection.
You can also restore files from a previous date by selecting the Date & Time tab in the menu bar and choosing a different date. If you’re restoring the entire Mac, you can also choose to erase the current contents of your Mac and reinstall macOS.
If you’ve used an external hard drive with Time Machine before, you might need to reclaim it after moving libraries such as the Photos or iTunes library to another location. This is because Time Machine is configured to only backup internal drives by default. If you need to claim an external hard drive that was previously backed up by Time Machine, select the option to “claim existing backups” in the Time Machine preferences pane and follow the on-screen instructions.
