As promised, I would write here whenever I succeeded to make encfs work together with GMailFS. Because Google is nice, but I don't trust them enough to have my files over there in readable format.

I tried encfs back then in October 2007, but that didn't work out. That was encfs 1.3.x. In January this year, version 1.4.0 was released and currently the latest version is 1.4.1.1. The ebuild is to be found in Gentoo Bugzilla.

Given the (ever increasing) storage size of a GMail account, it becomes interesting as an alternative backup storage location. The GMailFS project becomes an interesting option then.

Using Gentoo, I referred to Gentoo-Wiki.com where a howto was given on how to install GMailFS. This is a virtual file system, based on the FUSE infastructure. This allows you to enable support for a (virtual) filesystem without having to modify the kernel.
