just i've started dump on my / (19GB) filesystem with 1.7GB data to be
backed up (and about 5GB with nodump flag set)

it got into 93.39% done and now (at least 40 minutes) it's constantly
accessing disk and does not backup anything...

whats going wrong?!

dump -h 0 -0 -B 5000000 -k 64 -L "root-backup" -u /
