Open Source Mac Backup Software

DAR is a command-line backup and archiving tool that uses selective compression (not compressing already compressed files), strong encryption, may split an archive in different files of given size and provides on-fly hashing, supports differential backup with or without binary delta, ftp and sftp protocols to remote cloud storage Archive internal's catalog, allows very quick restoration even a single file from a huge, eventually sliced, compressed, encrypted archive eventually located on a remote cloud storage, by only reading/fetching the necessary data to perform the operation. Dar saves *all* UNIX inode types, takes care of hard links, sparse files as well as Extended Attributes (MacOS X file forks, Linux ACL, SELinux tags, user attributes) and some Filesystem Specific Attributes (Linux ext2/3/4, Mac OS X HFS+) more details at: http://dar.linux.free.fr/doc/Features.html

Backup P2P is a peer to peer application doing automated and secured backups inside a community (Jabber, XMPP). Each user shares some available space on his disk with others, to be able in return to remotely backup some of his own data.

Disk Optimizer selects files to be placed on any disk medium that will maximize the space used. It is very efficient in finding an optimum file set since it uses a Genetic Algorithm instead of brute force.

Moved to GitHub: https://github.com/mitchcapper/KeePassSync KeePassSync is a KeePass plugin that synchronizes your database using various online storage providers. This allows two or more computers to easily keep their data in sync.

Robbie is a cross-platform framework for backing up data on computers. It uses secure hashes to keep track of files, and when you alter them it sends the new version to your backup store - either locally or remotely.

partitioning backup recovery and all kind of boot loaders

dumpnet is a collection of bash scripts that allows you to backup multiple servers simultaneously. You can do incremental file system dumps with tar, dump and rsync, backup databases and much more. AIDE can also easily be integrated.

It is a small java eclipse plugin. This software makes workspace backups and restores them. You can use this plugin as workspace switcher too.
