My backup solution is fairly simple as I use robocopy to mirror my local backup to my remote backup server. I have set the robocopy script to run through Task Scheduler in Windows.
I did not want my backup server to have any connection to the network it was physically connected to. So split-tunneling was not an option.
I found a couple of sources that I used. One over at Tech 21 Century, witch i practically followed most of the way, and the the other over at Cisco for the internet access part.
Requirements
A TFTP server
The AnyConnect client software for your OS. Can be downloaded from here
In this example
The local network is: 10.1.1.0
The VPN network is: 192.168.10.0
Downloaded client software file: anyconnect-win-2.5.3055-k9.pkg
Cisco ASA Software Version 8.2(3)
Hardware: ASA5505
AD Domain FQDN: yourdomain.local
Here is the entire configuration I used: (don't copy paste the entire code on to your ASA, I recommend that you copy a line at the time)
copy tftp flash:

That's it :)Notes
default-domain value yourdomain.local
This is not nessasary if you dont have a domain. This is so you can access netbios names on your domain.

This is the part of the configuration where you enable access to the internet. If you are okay with split-tunneling, which uses the internet on the network where your client are connected, check out the article from Tech 21 Century below.Sources
