Whilst the whole rsync or other on-line solution is fine for those who
want that, my solution was a little more direct: use dump (ufsdump on
Solaris). Don't use dump on Linux, it won't work (so says Linus:
http://dump.sourceforge.net/isdumpdeprecated.html, except the links
don't work. Sigh. I can't find the direct link.). At least not on
live filesystems.

curious... I've been using dump for decades (unix and linux) without any
problems on mounted filesystems. And yes, I have restored successfully
from those dumps. Perhaps I'm just one of the lucky ones. Anyone with
half an ounce of common sense will use due caution backing up "live"
data, regardless of the tool used, and will prefer to work with umounted
filesystems when possible, but it isn't an imperative, nor always practical.
There are plenty of choices for all manner of backup and restore needs.
It's always best to consider all options first and find your way to
the one that works for you. And just because something doesn't work for
you (or for someone else) doesn't mean it won't work for the next sys
admin to come along. Simply present the options that worked for you and
let the OP decide what works best for them.
A good reference for back and restore is:
