NetBSD - Live Network Backup
dvl writes "It is possible but inconvenient to manually clone a hard disk
drive remotely, using dd and netcat. der Mouse, a Montreal-based NetBSD
developer, has developed tools
that allow for automated, remote partition-level cloning to occur
automatically on an opportunistic basis. A high-level description of the system has been posted at KernelTrap. This facility can be used to
maintain complete duplicates of remote client laptop drives to a server
system. This network mirroring facility will be presented at BSDCAN 2005 in Ottawa, ON on May 13-15."
I've been using der Mouse to copy files for years. First I user der Mouse to click on the file, then I use der Mouse to drag it to a new location!
Unfortunately the user interface for the relevant hardware has a very intuitive point and shoot interface.
