How to schedule backup of Brocade SAN switch configuration on UNIX/Linux

Brocade SAN switch can be backed up using Web tools or using CLI over SSH.
We can also schedule backup up of configuration.

Here is how to backup switch configuration from UNIX over SSH and SCP.

1, Generate key pair on switch as admin user:
SANSW:admin> sshutil genkey -rsa

2, Generate key pair on host as user used for backing up configuration (if you don't have it).
username@host:# ssh-keygen -t rsa -P ""
