DeltaCopy

Open Source BackUp software

DeltaCopy is an open source, fast incremental backup program. Let's say you have to backup one file that is 500 MB every night. A normal file copy would copy the entire file even if a few bytes have changed. DeltaCopy, on the other hand, would only copy the part of file that has actually been modified. This reduces the data transfer to just a small fraction of 500 MB saving time and network bandwidth.

Xfe can also efficiently complete terminal commands. Xfe is developed since 2002 by Roland Baudin, a french Linux enthusiast.
