Can I bakup like this...?? <--user mode Reuben?

[Keith Spencer]

Hi all, thanks to all replying.
I just spent many hours finding out my bakup strategy
was useless (didn't know what I was doing I guess)
Now I need to do it properly.
Ruben (and others)
Can I do the tarring of filesystems in a cron job
without being in single user mode?
I just followed a mostgraveconcern tute to move to a
larger drive and it worked well.
Lots of tarring etc BUT...all done in single user
mode. I imagine I cant do THAT and reboot etc etc in a
cron job.
I am going to try Ruben's idea and allay concerns by
having a removable 2nd harddrive so I can do this >
once to take a drive off site
So comments?
Is dump easier (for a dill like me) to use or
whatever?
What say you 
Thanks
Keith
