PuddleTag

Open Source Audio Tag Editor

puddletag is an audio tag editor (primarily created) for GNU/Linux similar to the Windows program, Mp3tag. Unlike most taggers for GNU/Linux, it uses a spreadsheet-like layout so that all the tags you want to edit by hand are visible and easily editable. The usual tag editor features are supported like extracting tag information from filenames, renaming files based on their tags by using patterns and basic tag editing.

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.

It is not actively developed.
