My friend runs 2 osteopath clinics and works between the 2 locations with another osteopath (they rotate which days they work in each clinic). A laptop stays at each clinic, and until recently were simply using a USB stick to backup all their electronic files. When either went to the other clinic they would manually "sync" their files across the 2 computers (using the USB stick).
After the London riots they realised they need to be smarter (one clinic was ransacked, laptop stolen).
When they first asked me I suggested an online backup service like Mozy, but now I understand they don't just want online backups, but to also use the service to keep the files on both laptops in sync so they can access the same file in either location.
What services/software are available? I'm not sure Mozy will work. Has anyone else setup something similar?
Additional Info:
It needs to be idiot-proof (both users are technophobes), and considering the confidentiality of a lot of the data - security is paramount. Last night's comments are raising that encryption is a must (I just assumed that solutions like Mozy would be encrypted and secure).
They're not looking for free - although "enterprise" is probably out of their league.
