[suse-security] Secure Backup

["Mario Ohnewald" <mario.Ohnewald@xxxxxx>]

Hello!
I have two boxes and want to save a backup of each others on it.
So far i have created a ssh key for both machines so i can make a ssh rsync
to each other.
But the terrible sideeffect is that IF one of those boxed get compromized
the cracker will be root on both of them!!!

My Backup script:
#--- START
---------------------------------------------------------------------
#!/bin/sh
speed=500
verzeichnisse="etc home root boot usr/local/bin/"

for verzeichniss in $verzeichnisse
do
        find /$verzeichniss -size +10200k | rsync -avvz --exclude-from=-
--delete -e "ssh" /$verzeichniss bortal.de:/backup/sts/
done
#--- END
-------------------------------------------------------------------------


I need to save it on each other because both have a 100MBit Internet
connection which makes a restoring backup easy! So a tape Backup is not really
possible. :/

Any ideas/hints?


Cheers, Mario
