BIG-IP : tmsh script to retrieve bigip.conf

There's a couple of ways of skinning the cat so to speak

xxx@(yyy)(cfg-sync Changes Pending)(ModuleNotLicensed:Active)(/Common)(tmos) save sys config ?
Options:
base               Base configuration.
binary             The configuration in binary format.
current-partition  The configuration in the current partition.
file               The configuration in the specified file.
gtm-only           GTM configuration only.
one-line           Display each configuration item on a single line
partitions         Partition list
user-only          User account configuration only.
wait

And as far as backups go, i have a shell script that runs via a cronjob. The script performs a nightly backup and pushes it to an ftp server.
