I am a long time user of IDEA and I also use the EAP releases. This exposes me to a bunch of bugs over time. As a result some of the problems that developed on my machine, are apparently not reproducible elsewhere but are very sticky on my machine. These problems survive upgrades of both EAP and production versions. For example, all search functionality in the IDE help stopped working a while ago and no upgrade since fixed it. More annoyingly, whenever I do search and replace the current buffer scrolls to the top and I lose my edit location in the buffer (it seems that other people had this too, but it does not happen on my laptop).
Anyway, I am happy to do a clean install (remove everything in .IntellijIdea10) and start over. No problem, except that in the process I would lose all my cutom settings, which are scattered all over the place. Naturally I would also lose any plugin specific settings, which is not as critical but very uncomfortable.
The question is - does anyone know a reliable way to backup and restore all settings (can assume that we remain on the same version of IDEA)? I looked around and found no discussion that documented any way to do it. I would be happy with an answer like "copy away the following directories and restore them after the re-install"
