Good Grief, Charlie Brown, you're such a nice guy.
I don't do anyone's backups. When something fails and I ask, "Where's your backups?"
If they say, "What Backups?????" I laugh (to myself) while watching them cry.

If I were in total data and system support it would be different.
But I don't charge for it and they don't want to pay for it.

Way to go and thanks for the info.
