Currently I use partimage to make full system backups.  That's fine to
restore an entire system to its condition at the time of the last
backup, say in case of a catastrophic hard drive failure.  

But any changes since the last backup are of course lost, and with
partimage, I can't restore just a file or part of a filesystem, I can
only restore entire partitions.  

So I was wondering if rsync could be used to do a full backup of a live,
running filesystem, from within that filesystem (Or does that need to be
done from outside the filesystem, say from a rescue "live cd").  

Or would I still have to use both partimage for full partition restores,
and rsync for partial filesystem restores and incremental backups?
