Problem this snippet solves:

BIP-IP backup script with SCP transfer option. First version works with 10.2 (bigpipe) command. Second version works with 11.2 (tmsh). 11.2 version also contains some logic fixes.

This script creates tar.bz2 archives which include a .ucs file and a .scf of the F5's configuration.

It optionally stores them locally and/or transfers them to a remote system using SCP.
