Braincracks acts like a continuous snapshoting filesystem / versioning filesystem. It monitors folders for files changes (each X seconds) and saves a copy of files when they change. It is made of 3 Bourne Shell scripts (1 bin, 1 daemon, 1 service).
cvsbackup is a perl-based tool for backuping your files and sending diffs via e-mail. package also includes scheduler (optional) which helps you monitor more than 1-2 servers (helps to prevent high loads on config repository).
The aim of this project is to make it easier to keep the source code updated with the server on projects that use CVS. Keeping up to date source files on SourceForge.com projects will be automated.
