Our family's desktop is used by myself, my wife and 3 teenagers I want to do my best to protect its current state...assuming the state is (relatively) problem free. My hope is that as an inexperienced user that I can easily *exactly* backup the drive so that if there was a serious problem say...virus/bad software installation/teenager 'stuff' that I could quickly and easily restore the drive to its 'perfect' state ie OS, software and data just as it was. Is this known as imaging? After some web researching I dloaded the trial version of TI 10 and bought a WD 2.5" external 160 gig HD. (The desktop in question has an 80 gig HD with about 50 gigs used). The other night I thought I did what I described above but now I think all I did was a backup the entire HD, using the Acronis "Create Backup Wizard" . That is I selected "My computer" checked off the desktop's HD and directed the backup to the external USB WD HD. Instead it is "Clone Disk" I am wanting under "Manage Hard Disks...right? Can I do the clone on my same 2.5" drove that I have mistakenly backed up "my computer"? I have created the "bootable rescue media" dvd. Am I missing something in my description? Btw, if one does a clone rather than a backup is it still a simple matter to obtain *just* certain data files...say my digital picture files?
