Hi not sure if this is in the right place but here goes

At the moment I have an Iomega Zipdrive but the storage capacity is nolonger large enough.
The software I run to suport automatic back-up is Quiksync

If I buy an Iomega external hard drive will I be able to use this same program or do I need something else, if so what?

Their retrospect software is too pricy for me and I'm not sure it's what I'm looking for.
