I have seen some posts lately refering basically to recovering your amanda
backup server in case of failure. i.e. if you have to rebuild your backup
server and you want to restore all your amanda data, etc.

In particular "amadmin export". What I am currently doing is this:
tar -cpPzf /home/myname/cjs-amback.tar.gz /var/lib/amanda/ /etc/amandahosts
/etc/amandapass /etc/amanda/ /var/log/amanda/

Then I scp that file to other backup servers. And the other servers do the
same. 
My question is: Is it necessary to do the "amadmin export" also?

Thanks,
