</div>It seems dump is not available for ext4 at present anyway, so I'm stuck<br>

is. I saw some vague references to speed improvements (meh, it runs at<br>

there doesn't seem to be much info on why it is a better choice, just<br>
that it works differently.<br></blockquote><div><br>The fact that it does incremental backup natively, understanding the <br>difference between a full and an incremental. It also does many levels<br>of incremental if you need that (Tower of Hanoi scheme).<br>
<br>The fact that it works on the file system level also has advantages. You<br>can restore a partition EXACTLY to what it was before.
