Warren's (fabulously lucid) page brings up a question for me. For years 
I have used a 'pull' strategy for across-the-LAN backups, w/ my 'backup 
servers' using tar or rsync to access data for backup on NFS-mounted (or 
automounted) directories that I want backed up. This all happens 
automatically overnight under cron. I am usually *not* backing up system 
files, but rather user data, although I have recently started backing up 
system stuff as well. Warren's page consistently illustrates a 'push'-ed 
backup, & involves system files. I am *dead* serious about automated 
backups, no possibility of forgetting to do it that way, but I always 
thought that trying to backup 'live' system files was a bad idea 
(right/wrong ?). There doesn't seem to be a way to do a 'push' backup 
w/o messing with live system files. I guess I am asking about 'best 
practices' for backups, & the wisdom/validity of backing up 'live' 
system files. Sorry for rambling, but the question(s) popped up for me 
while reading Warren's web page. Any input appreciated. Have a nice day 
& weekend :-).
