From Lupinhos: HardlinkBackup is a simple, fast backup program for incremental backups, which uses hard links, schedule backups, send e-mail notifications and can automatically delete old backups. HardlinkBackup reads the source directories and compares the files with previous backups. Only the modified files are then copied the unchanged files are linked with hard links to the files already existing backups (assuming that the target drive supports hard links, eg formatted with NTFS). In this way is always on the backup drive a complete copy of the source directories on the respective date. However, only the space plus a copy of the changed files is required. If an old backup copy is no longer needed, they can be disposed of without problems, simply by using the appropriate backup directory is deleted.
