Backing Up Specific Files to Server

Hi Guys,

I am setting up a small home server running Server Essentials 2012 R2 and I would like my imac and Macbook Air to A) perform Time Machine backups to a shared folder and B) Use crashplan to remotly backup most critical files such as family photos, important document scans etc.

No from what I have read it is not a good idea to get crashplan to remote backup Time machine Backups, and instead I should remote backup only specific files or folders.

I do not really want to pay for the 'Family' crash plan package which I would need if each Mac had it installed and backing up files, instead I would prefer just the single user package and have it work on the server. This means though that I need a method of backing up specific files that are locally stored on the Macs to the server, where crash plan will then back them up remotely also.

Can anyone recommend a way to do this for specific files and folders separate to the Time Machine backups.
