||Making the Jump to Subversion|
I've been using subversion for production code since 1.0 and have experienced two complete repository failures (that's almost once a month). This is with a local repository and a single user. In over seven years of CVS usage I have never lost a repository like that.
I still use Subversion because it has features I've always wanted that CVS lacks but after that first failure I have implemented nightly incremental and weekly full backups. The second failure I didn't lost a thing.
Support Subversion but make the jump with your eyes open and your repository backed up!
