What online backup tool allows you to: A) Back up Windows, Linux and optionally Mac desktops and servers to the cloud B) Do so by first backing up to a central server or appliance C) Allow restoring from that appliance when possible and if not go to the cloud For now the best option I have seen is i365 by seagate with an appliance between the local computers and the cloud. I know Microsoft also has an i365 plugin for DPM, as well as an Iron Mountain plugin. However, I feel that there must be a simpler way to do this. Can any of the "simpler" solutions like Jungle Disk or anything else going to s3, Mozy, Carbonite, Crashplan, etc do this? Thank you
