Sounds like journaling at the sector level. How does all that change get replayed after the snapshot is done? I'm starting to think it might be better to go back to using rsync on mounted filesystems. -- ----------------------------------------------------------------- | Phil Howard - KA9WGN | Dallas | http://linuxhomepage.com/ | | [EMAIL PROTECTED] | Texas, USA | http://phil.ipal.org/ | -----------------------------------------------------------------
