My local linux users group in Colorado is having a very interesting
conversation about disaster recovery on their mailing list.
Let's assume someone types fdisk on my windows boot partition and I need to
I'm told I can network boot windows across the public internet if I can open
up enough ports on the intervening firewalls. Can I use the cygwin ports of
rsync or rdiff-backup initial create a remote repository and later restore a
bootable windows partition and then boot locally?
