Bu (Pronounced B-U) is a convenient, simple to use, yet powerful incremental command line backup tool for Unix based operating systems such as Linux or BSD. It is designed to backup files to other file systems as opposed to backing up to tape like traditional backup systems. The backup file system may be local, an NFS mount, or a remote file system accessible via ssh or rsh (currently supported by the new rbu utility which uses rsync and will eventually replace bu).
Ohloh computes statistics on FOSS projects by examining source code and commit history in source code management systems. This project has code locations but that location contains no recognizable source code for Ohloh to analyze.
