Backups in the cloud.

Given that 1TB of backup from Google is now 10$ a month, I had to look into doing cloud backups again.

Google doesn't have a native Linux client. So one has to use google-drive-ocamlfuse. Installing this on CentOS 6 is surprisingly complex. And Google Drive's auth mechanism is based around a web interface.

But once I got it working, it Just Worked. Or rather, I could copy small files to ~/googledrive, see them via the web interface, delete them there and they are now missing.

Of course you wouldn't leave unencrypted backups on Google's servers. I futzed around with gpg a bit, but maybe layering encfs on top of google-drive-ocamlfuse would be a better idea.

My experimetation was cut short by supper, and by the fact that uploading a 400MB file was very slow :-) (sent 418536429 bytes received 31 bytes 219416.23 bytes/sec aka 1.6 Mbit/S)

For the record, here is how I installed google-drive-ocamlfuse

yum install m4 libcurl-devel fuse-devel sqlite-devel zlib-devel \
    libzip-devel openssl-devel
curl -kL https://raw.github.com/hcarty/ocamlbrew/master/ocamlbrew-install \
    | env OCAMLBREW_FLAGS="-r" bash
source /home/fil/ocamlbrew/ocaml-4.01.0/etc/ocamlbrew.bashrc
opam init
eval `opam config env --root=/home/fil/ocamlbrew/ocaml-4.01.0/.opam`
opam install google-drive-ocamlfuse
sudo usermod -a -G fuse fil
google-drive-ocamlfuse 
google-drive-ocamlfuse ~/googledrive

The second to last command will open a browser to get an OAuth token. This means you need htmlview and a valid DISPLAY. The token is only good for 30 days. This is something that needs to be better automated.

Hi
Trying follow your instructions to install google drive ocamlfuse on centos 6.7 and I got an error with the line

source /home/fil/ocamlbrew/ocaml-4.01.0/etc/ocamlbrew.bashrc:
bash: /home/fil/ocamlbrew/ocaml-4.01.0/etc/ocamlbrew.bashrc: No such file or directory

/home/fil is my user home directory. Obviously you have to change it to your own user.
