Build your own private, encrypted, open-source Dropbox-esque sync folder

Prerequisites:

• One or more clients running a UNIX-like OS. Examples are given for Ubuntu 12.04 LTS, although all software components are available for other platforms as well (e.g. OS X). YMMV
• A cheap Ubuntu 12.04 VPS with storage. I recommend Backupsy, they offer 250GB storage for $5/month. Ask Google for coupon codes.

Software components used:

• Unison for file synchronization
• EncFS for folder encryption
