There are at most three backup tools appearing on the Acer Upgrade Wizard. How should I choose from them?
Each of the backup tools has its functional scope. For example, Acer eRecovery Management can backup and your whole system volume, whereas NTI Backup NOW! and Backup Utility for Windows can backup your individual data files and settings. I recommend you to use all of them to backup your system before upgrading it. At least, you are highly recommended to backup your full system volume to CD/DVD with Acer eRecovery Management.
