That's what I suspected - the app is in an I/O wait (technically,
"uninterruptible sleep"). Usually this is due to an NFS hang, although
it can be caused by other media which has wedged but not timed out. One
trick which sometimes works is to unmount the mount point it's stuck
on.. if that doesn't work you're pretty much stuck.
Are you running a
script that kicks off more than one backup operation?
Such as one for each file system?
In that case you need to kill the parent process first. Otherwise the
parent will just kick off the next child process in line.
