Therefore, if you would like to backup external hard drive with it, first you need to format your external hard drive. Then remove the external drives from the excluded list.

How to Configure and Customize Time Machine backups

Exclude items you don't need: If you don't need to save some items, you can select items to omit from your system's regular backups. Go to Time Machine preferences pane and click "Options". Then click the plus-sign (+) button under the list labeled "Exclude these items from backups". From there, pick and choose the items you'd like to leave out, and click "Exclude" when you're finished. In the large Exclude list, you'll see the folders or individual files that you selected. You can change your mind about these at any time by selecting a file and clicking the minus-sign (-) button.

Erase older backups without interruption: When your external drive gets full, Time Machine will automatically erase older backups to make room for new ones. The default setting is for the program to notify you when it has deleted an older backup, but if you don't need this information, uncheck the box next to "Notify after old backups" are deleted in Time Machine's preferences.

Backup on battery power: If you're a MacBook user, you can also choose to back up while using battery power. Go to Time Machine's preferences, click "Options", and select the "Back up while on battery power" option. By default, Time Machine will back up only when your laptop is connected to AC power, to ensure that your MacBook stays powered during the backup process. If the battery drains completely during a backup, the backup won't be complete and may get corrupted.
