Hi Dave, Chaps,
Thanks for the feedback! In response to Dave's comments I will respond with a few in-line comments if I may.
Both of you have second internal drives that you could be using if they have enough available space.
I cannot vouch for Mr.Frisbee, but as mentioned previously I have always done backups to an external drive because of what happened to my neighbours computer when his house was struck by lightening, it's peace of mind thing!
I agree with you that it's safer to hold images "outside" the system but "Offsite Copies" are Copies and should not be the only source of a backup.
Why not? An inernal backup is only any good if you machine hasn't just gone bang!
The biggest advantage of an offisite copy is actually redundancy, the second advantage is being able to store that copy "outside" the computer or in a totally different location to protect against things like lighting, fire, flood, or theft of the entire computer.
You hit the nail right on the head there Dave.., "to protect from things like lightening" Very True!
But the "main" location of the images should be on an internal drive because the majority of the time you need to use an image is because of software problems, windows errors, virus infections or hard drive problems.
This seems a rather pointless comment, what happens when a virus attaches itself to your backups? What happens if something malfunctions in your computer and sends a surge though all your hard drives? I think perhaps you're assuming that most people are like you and maybe do a lot of bench work and testing with their computers. Maybe not everyone does that sort of thing and so it's unlikely you need the backup available 24/7.
If I need to restore my system because of the problems you mention I simply slide my SATA drive back into the front of my machine. It takes less than 10 seconds to do this! At all other times my SATA drive is stored in a fire safe near my front door away from harm.
You can't be running off to the bank to get your external drive out of a safety deposit box every time you have a problem with windows. Likewise, most people will have a hard time keeping an external drive updated with current images unless that external drive is plugged into the system every day to update the image. If you need to have the external connected to your system every day your defeating the purpose of an offsite copy.
I think that would be taking it to the extreme to store your hard drive in a safety deposit box, like any of us could afford to do that! You do however make a somewhat contradictory statement,
"Likewise, most people will have a hard time keeping an external drive updated with current images unless that external drive is plugged into the system every day to update the image. If you need to have the external connected to your system every day your defeating the purpose of an offsite copy".
I think we need a reality check here, how many ordinary ghost users really backup their computer every day?! Your last paragraph suggests that because "most people would have a hard time keeping an external drive updated" your words, not mine! It is unlikely they would bother to keep an off-site copy as well. More fool you then, that's all I can say. Did I hear a thunder storm brewing?
If you have the available space, try scheduling images onto an internal drive and use the external drives for offsite copies like they were designed for.
Assuming you're referring to external USB drives, I wasted almost two years trying to get Ghost to work with those as mentioned earlier in this post. I bought three new USB devices for that purpose and ghost failed to work correctly on all three! I even have a new machine now and the problem still existed on this machine too! I also spent nearly a whole week with your tech support team and they failed to locate the problem either. Eventually they upgraded me to Ghost 15.0 and even that failed to resolve the problem.
The SATA drive option I now use has none of the problems I suffered before and as it is my only workable option there's not much I can do either way. I can tell you that it is much more practical than having to plug something in externally, I just slide it into a 'hot swap' SATA Caddy which is occupying a spare 5.25" bay port on the front of my machine. Job done!
To round things off, I'm sure none of us mind being offered words of advice from other forum users but surely it is for the customer to decide how they do their backups? The important thing surely is that we do do them?! 
Dave
All the best
Tyler
