Just send to your new address if you are not comfortable using the import/export private key feature (under tools).
You could achieve this with some complex networking, will probably have to hire someone to come out but:
>Create a network share on the laptop
>Note the locations of your current backup files
>Create a powershell script to automatically copy the backup files to your network share on the laptop
>Create a scheduled task to run that script every 6 hours or so
As I said a little complex but that's the only way I can think of doing it.
EDIT: Another option may be: purchase a RAID card for your PC and an extra HDD (same space as original HDD).
Then setup raid 1 which will mirror both hard drives 24/7 for redundancy.
You just gotta pray nobody breaks in and steals your computer.
