Backup customizations etc

Hi all

We have our network set up with a separate server running the ERP system (currently vista 8.03.408 but we are upgrading next couple of weeks to E9).
For some reason (mainly cost) we have no backup tape on that server so we backup the database to the other server every day where in turn it gets backup on tape.
My question is what's with all the customizations how do I back them up? Where can I find all of them and all of the BPM we have.
I know that all the .p files I created for the configurator I have to copy too , same goes for crystal reports customized.
Is there anything else needed to be backed up?

Thanks
Ephraim Feldman
