- Selectively back up the content on your Mac - With Time Machine, you have to make a backup of all the supported content
- Save more space on the target device - You can compress the backup to free up space on your disk.
Based on these features, I recommend you choose EaseUS Todo Backup for Mac as your backup option, which is easier and more flexible. If you prefer Time Machine, jump to the corresponding guide here.
