I wanted to backup a brocade san switch configuration, and tried SaveSimplyYourSan - but it wouldn't do ssh - and using telnet, uploading config to ftp - is too unsecure for my taste.

I ended up writing a small expect script that looks like this:

#!/usr/bin/expect
#exp_internal 1
set prompt "admin>"
set timeout 20
set Machine [lindex $argv 0]
spawn ssh -l admin $Machine
expect -re $prompt
send "configshow -all\r"
expect -re $prompt
send "exit\n"
exit

You put this in /usr/local/bin/savesanconfig.expect and run it with the hostname as the parameter.
The script requires that you have added the ssh public key of the user doing the backup to the admin user on the switch - as to not require login.
I prefer that, to including passwords in scripts :)
