I keep all my data files in a shared folder on my desktop.

I back up my .pst to another shared folder on my desktop, 1 minute before I walk away with the notebook.

On both, "Offline files" (Tools/Folder Options in Windows Explorer) is enabled.

On my notebook, I map to these 2 network drives. The files are still available when I unplug the notebook from the dock.

The worst case scenario is that if my notebook is stolen, I've only lost any new or updated files (apart from critical ones which I still put on a floppy or CD-R).

Back in the office (or if I use a VPN), the notebook automatically synchronises the files.

Each computer backs up the other.

Each computer's backup is "offsite".

The restore, which I've had to do once from notebook to desktop, and once from desktop to notebook (stolen grrrrr), was simply reinstalling OS, reinstalling apps - usually 2-4 hours.

I'm not as quick as ScottC - but both the backups and restores work.
