Greg:
I wonder how many guys store their backups in the 'clouds'??
John,
An interesting question you ask.
This "cloud" based storage thing has been marketed by everyone's favourite company, Google.
You'll never see me using it, I mean, for the time being it is free to everyone that uses it.
There will be an on-line riot the day that Google starts charging for this service and by then, they have you by the short and curlies.
