I keep the source code of my projects in my Ubuntu One as a back up.
In the past it worked and I never had any problems. I had to change the hard disk of my laptop so I installed a fresh Ubuntu 12.10 on the new drive.
Ubuntu One downloaded my files the first time I connected. But when I checked on my projects, almost all of my C++ source code files were missing!!! I tried to check if I still had them on Ubuntu One by accessing from the web but nothing... my work is lost forever.
I don't know who to ask for help? Is there a way to get back my precious files? Honestly I can't trust this service any more, I'm very disappointed.
Thank God I found a back up in one of my external hard disks. I won't trust Ubuntu One any more, it's buggy and quite slow.
