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

cdc-file-transfer is a bandwidth-efficient file transfer and sync tool that uses content-defined chunking to detect and transmit only the parts of files that actually changed. Unlike fixed-size blocks, content-defined chunks are cut at data-dependent boundaries, which means shifts and insertions don’t invalidate the rest of the file’s delta map. The tool maintains chunk fingerprints and a manifest so it can de-duplicate across versions and even across different files that share regions of content. This approach makes it well suited for large logs, VM images, and binary assets where small edits would otherwise force full re-uploads. The implementation focuses on being robust over unreliable networks with resumable transfers and integrity checks that verify every chunk. ...

This is a source delta update program which allows you to patch compressed tarballs and retain the original MD5sum. Very much like diff/patch.
