Clone will copy one disk to another or one partition to another (unallocated space is also supported). Usually, this option is used to upgrade the current disk by creating an identical copy.

As a computer newbie, what features should I use to protect my computer?

You can use System Backup to back up the system and boot partitions, use Disk/Partition backup to back up the data partition and add plans to run an automatic backup. If you use the computer frequently or have software that may cause boot failure of the computer, we would suggest you back up the computer every 1 to 2 days. For other situations, you can backup the computer once a week. In addition, you can schedule File Backup to back up the files which are changed frequently.

What kind of storage service should I use to save my backup images?

EaseUS Todo Backup can save backup images to internal disks, external disks, network drives, or free cloud(Google Drive, Dropbox, and OneDrive) and CD/DVD.
