Freedup walks through the file trees (directories) you specify. When it finds two identical files on the same device, it hard links them together. In this case two or more files still exist in their respective directories, but only one copy of the data is stored on disk; both directory entries point to the same data blocks.

Rsync partially does this, but it won't search for identical files within your backup. This software does just that. '''In my case I saved ONE THIRD of the backup diskspace on one single backup alone.''' And what is more, FreeDup found more identical files within backups' trees themselves, hence correcting Rsync and saving me terabytes of space.

In my case I saved ONE THIRD of the backup diskspace on one single backup alone. And what is more, FreeDup found more identical files within backups' trees themselves, hence correcting Rsync and saving me terabytes of space.
Without FreeDup's hardlinks my current off-site backup would be 3.4TB, but instead it is only 270MB. That is 12 backups in total - 3x monthly, 4x weekly and 5x daily backups + the current backup running. - [[User:Giskaard | Giskaard]] ([[User_talk:Giskaard|talk]] | [[ Special:Contributions/Giskaard| contribs]])
