It's normal to take several hours to finish a restore from Time Machine, however, if Time Machine shows 'searching for Time Machine backups' for more than 30 minutes or even an hour, obviously your Mac is getting stuck at the process and it will take forever to finish unless you apply some measures to tackle it.

Time Machine is the part of macOS that allows you to easily back up your Mac to an external or networked hard drive. Here are some of the most asked questions about Time Machine, such as what size hard drive do you need, can you exclude files from the backup, and how do. Time Machine works with your Mac and an external hard drive (sold separately) to automatically back up your entire Mac, including system files, applications, accounts, preferences, music, photos, movies, and documents. Time Machine automatically makes backups every hour, every day, copying just the files that have changed since your last backup.

How to Fix a Time Machine Backup Failed?

Unfortunately, several Mac users, after updating their Mac, face Time Machine backup failed error. If you are one of those unlucky users, here are some troubleshooting tips to fix the problem.

1. Check External hard drive’s file system.

If your external drive doesn’t have enough storage space or is formatted wrongly, you might face Time Backup error. Therefore, you need to make sure the external drive you are using has a native macOS format. The FAT or NTFS file system doesn’t work with Time Machine.

Besides, if the external hard drive is in APFS macOS format then also it won’t work with Time Machine backup.

To check the format of the drive you are using, follow the steps explained below:

1. Attach the external drive to your Mac.

2. Now, launch Finder.

3. Here, look for drive> select it > right-click Get Info.

4. This will show drives format under General information.

If the external drive you are using is having one of the incompatible formats, you’ll need to reformat it to Mac OS Extended (Journaled) with a GUID Partition Table (GPT).

To do so, you can use Disk Utility. Follow the steps to format the external drive:

1. Attach the external drive to Mac.

2. Open Finder > Go > Applications > Utilities > Disk Utility

3. Open Disk Utility and choose the attached drive (external) from the left pane.

4. Click Erase present at the top of the Disk Utility window. As shown in the screenshot below:

5. In the new pop-up window that opens rename the drive if you want and alters and drive format to the supported one (Mac OS Extended (Journaled) > Erase.

This will change the format of your external drive and will make it compatible with Time Machine. Now you can take backup using Time Machine.

2. Check free disk space on external drive

If you still face any problem check for the available space on external drive. There should be enough room to back up the Time Machine. If that’s not the case get rid of unwanted files stored on it and free up space for Time Machine backup. Alternatively, you can use a new external hard drive or one with enough available space.
