bigsync is a very simple backup tool for large files. You can create backups of files on the local machine, or of files on remote computers (using ssh).

Backups created with bigsync are split into chunks of some megabytes of size. These chunks are then zipped and organized in a directory hash.

Backups can be done incrementally using hardlinks; in this case, a reference backup can be specified in addition to the source and destination of the current backup process. bigsync then tries to reuse (by linking) as many of the data chunks as possible for the new backup.
