One could argue that rsync has a design flaw, since (as mentioned in
the article about dump) it will set the atime of each file that is
opened for reading. Besides, any tool that takes time to read files
from a file system, while that file system is being modified, has
either a design flaw or a paradigm flaw.

As mentioned in the article: use LVM, take a snapshot (meaning the
file system you're will be coherent during the time from reading the
first byte to the last), then dump or rsync that snapshot. I haven't
done this myself though - but if (any of) you want to demonstrate the
process at CLUG, I'll be there eagerly awaiting the meme transfer =)
