A dusty little corner of the Internet: electronics, computer hardware and software, general aviation, 1980's Mopars, and related sundry.
bup is a backup and restore tool that uses tar to create archives. The archives are automatically named and split into 1GB chunks to accomodate any file system. The archives are optionally compressed using bzip2. It is essentially another wrapper for tar, which can be a pain when the backups are large. I haven't found one that is as easy to use as this one (at least for me). I do all my backups to a remote machine with a removeable hard drive bay via NFS.
