Yeah, Seagate and Acronis are in bed together with making a custom, but less feature packed version of their titled Acronis software that does the job any typical user backing up their own system would find to be useful.
That's pretty cool and a way for Seagate to drag in a couple more sales since it's very enticing to customers, but I'm just too stuck in my open source uniform ways to even consider trying it - and I even run Seagate drives.
I use a bunch of different programs for different things.
Clonezilla Live - to back up my dual boot system.
FOG - to mass image Windows machines. (I've heard rumors mac and linux support is projected for the future)
If I had to mass clone Linux machines, I'd probably look into Ghost 4 Linux, but so far being in a Windows environment at work I haven't had need to look at anything else since the 2 needs I have for imaging are answered with the 2 programs above.
Glad to hear you're utilizing some sort of imaging software though. I can't tell you how helpful it was when my system crashed and I was able to at LEAST push my Vista image back to my computer via Clonezilla Live.
