Yes, it happens. CRX has lost my sources from one day to another. As usual you realize that you need a backup when it’s too late. So the question became: how can I backup my sources outside the crx? Packages!
First you have to create a package of what you want to backup via the package manager provided with CRX. I wont go in details of this operation. Then you can call every package operation from a command line like bash and curl application. Fortunately Mac OS X and Linux come with cURL out of the box so nothing special is needed.
Just download the pdf containing the bash code, fix the variable according to your needs and schedule it or execute by hand.
The script is missing at all the error checking and some other things but works well for the moment; maybe in the future I’ll start a new SF project with the script source.

An even better approach would be to use a version control system that allows you to jump back to specific snapshots in development, not only in case of disaster, but also to be able to roll back changes more easily. Our developer documentation shows how to synchronize CQ5 with SVN but other version control tools (such as git or bzr work as well).
Thanks Lars. I know the eclipse+vlt+svn and I use it, but for little projects/experiments I don’t want to set up all that “circus” 🙂
BTW CQ5 rocks!
