what I do for myself, is a local Synology NAS in RAID1 configuration for synchronizing all business documentation, such as offers, invoices, salary statements, etc. Every night the NAS compresses and encrypts the whole archive and pushes a copy to a VPS at the provider site. This way I am sure I have a relatively recent off-site copy, and it is secured enough, so that even the VPS provider is unable to read it. I use GoodSync for synchronizing my documents folder with the NAS. Also NAS is reachable from the public internet over HTTPS, and I can synchronize my files when I'm at the customer site. Also I use another VPS (extremely cheap one from http://www.buildyourvps.com/ http://www.buildyourvps.com/ -- a bit slow, but fine for these needs) as my Git storage. I use Gitolite to organize my Git repositories, and basically create a new repository for every set of scripts or configuration files that I do for my clients. For public and open-source code, I use Github. A third VPS is used as a virtual PBX where I organize hotline service for those of my customers which need support with an SLA. You can see some technical details in my blog (http://txlab.wordpress.com/tag/dvop-net/ http://txlab.wordpress.com/tag/dvop-net/). Also an instance of RT: Request Tracker is running on it.
