Turn on root logins in /etc/sshd_config on receiving machine This is a great summary. One note I would stress is that you dont need to necessarily login as root on the other end. You could setup a dedicated account per machine that your are dumping from, or have one generic account that takes all the dump files from various machines. e.g. on machines A and B. root on A does something like /sbin/dump -0uanf - /home |gzip -3 | ssh -c blowfish machine-a@backuphost.example.com dd of=/backuppath/machine-a-uid-home-dir/dump-home-l0.gz Not entirely sure if its correct, but some crypto guy told me blowfish was a better encryption protocol in terms of speed for an application like this. I also like a bit of compression on the file. This is done on the client machine, so that the CPU gets spun there, and not on the target machine. ---Mike Mike Tancsa (mdtancsa@sentex.net) Sentex Communications Corp, Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers could setup a national IP network."
