bup - towards the perfect backup - wrouesnel_blog

Since I discovered it, I’ve been in love with the concept behind bup.
bup appeals to my sense of efficiency in taking backups: backups should backup the absolute minimum amount of data so I can have the most versions, and then that frees me to use whatever level of redundancy I deem appropriate for my backup media.
But more then that, the underlying technology of bup is ripe with possibility: the basic premise of a backup tool gives rise to the possibility of a sync tool, a deduplicated home directory tool, distributed repositories, archives and more.
More praise for bup.
