Secure Online Data Backup using Duplicity

This is part two of a series about encrypted file storage/archive systems. My plan is to try out duplicity, git using transparent encryption, s3-based storage systems, git-annex and encfs+sshfs as alternatives to Dropbox/Wuala/Spideroak. The conclusion will be a blog post containing a comparison a.k.a. “executive summary” of my findings. Stay tuned. Duplicity is a command-line tool similar to rsync: you give it two locations and it synchronizes the first location to the second.

Avoiding Internet/Network Surveillance

Last week’s World Conference on International Telecommunications (WCIT) brought internet surveillance into public news: one outcome of the conference was standardization of DPI technology. This infrastructure standard will make it easier for governments to implement large-scale surveillance and/or filtering. Funny thing is that governments are already having those capabilities, they only want to standardize it. The public outrage came too late. So let’s protect you from governments at home or abroad, the RIAA, MPAA, random eavesdroppers and anyone else that want to listen in on your secrets while you’re surfing the Internet.

Linux: How to encrypt your data on hard drives, USB sticks, etc.

Imagine your Laptop (or Desktop Computer) being stolen. How long will it take and how much will it cost you to get back on track? Hardware will be easy: the cost for a new premium desktop is around $1000, for a new Laptop around $2000. Your data “should” be always be back-uped somewhere anyways. But this neglects a hidden cost: some thief has all your data, including all your online identities, photos, source for software projects and private notes/pictures that you do not want to be published.
