Well so far the only requirement for me has been a >= drive, no
problem, negligible loss (depends on how you define it, 17megs
max in my case), very simple and 0 cost.
I just did a copy at aprox. 104mb/m and switched to running on the
backup drive (shutdown, swap drives, boot, fsck) in aprox. 10min. The
dd process used almost no memory and cpu usage seemed to run 11-16%.
There may be limitations/problems that I haven't run up against yet
but I don't know of any harm that could come from trying it.
