Scylla Charybdis lets you get a data odyssey done with the help of two small monsters. It's easy to use, utilizes SSL (encryption), LIBZ (compression), and simple password protection. A builtin timeout detects link breaks (for dialups) such that an uploads can be automatically continued from where it broke (within a file). MD5 sums detect if files are successfully transferred. In case of data changes the destination is renamed and not overwritten (backup history). Data throttling can prevent the transfer from using up full link speed, such that a background upload does not disturb your SSH sessions (like SCP does).
