Podcast 84 rsnapshot

rsnapshot

rsnapshot is an open-source backup and recovery tool based on Mike Rubel’s original concept. It is designed to take a great idea and make it more accessible to users and more useful for larger environments. Under the hood, rsnapshot works in the same way as Mike Rubel’s original scripts covered in the first part of the chapter. It uses hard links to conserve space and rsync to copy changes and break the hard links when necessary.
