bita – differential file synchronization over HTTP

bita is a HTTP based file synchronization tool striving for low bandwidth usage through data reuse.

bita is a generic file synchronization tool but has been developed with software update of embedded/IoT systems in mind.

Software update is a typical case where bita may provide significant bandwidth reductions, where one can expect that a new software image will contain a lot of data already present on the system being updated. bita can identify the parts (chunks) already present on the system and fetch the missing ones from remote, still outputting an exact clone of the archived source file.

No need to pre-build patch files for going to/from different release versions. No need to run any special file server. Just bita compress the release image, upload the archive to any HTTP file hosting site. And bita clone the archive using whatever local data is available on the system.

This is free and open source software.

Key Features

  • Clone from remote while reusing data from any local file or device.
  • Clone using a file or block device as output.
  • Host archives using any regular HTTP/HTTPS server or service.
  • Include in your own project with the bitar library.
