[CentOS] Backing up my server...

Helo, I've just installed a CentOS 4.0, postgress,iptables, ect.. on a P 4 Intel using sotf RAID 1 ...and everything is fine. I bought a HP DLT 40/80G tape device for being use as tape backup to my server. My questions are:

1. What you recomended me to use as a soft backUP. (amanda, dump/restore, TAR scipts, other)? 2. How can I backUP my entire filesystem ..(I mean everything using one the above software)? 3. What software can I use to put this data into my tape device (HP DLT 40/80 G).? 4. Is there only one software which do everything I want?

NOTE: I am looking for some software which makes me a quick/easy backUP and quick/easy restore...

thanks in advance
