    NoDoubles

    Finds and removes duplicates (hard links)

    NoDouble is a duplicate correction tool. It scans your drives for duplicate file. Unlike most tools, it replaces duplicates with hard links. A duplicate file is file with the same content, the same size, but not necessarily the same name or extension. When two duplicates or more are found, at least one of them is replaced with a hard link that points to the same data in the first file. Effectively, a hard link is a file, not a shortcut, and by removing the first file, the second file will still be present with all of its data. However, modifying one of these files leads to the modification of the other.

    ZipBackup

    ZipBackup

    Back up your files into zip and encrypted zip files.

    ZipBackup is a free Windows tool for maintaining backups of your files and folders. ZipBackup focuses on providing simple file backup in an open, common file format instead of a proprietary format that locks you into a particular backup software. Full and incremental backups are automatically provided. ZipBackup also supports 256-bit Advanced Encryption Standard (AES) security for your zip files - the same security used by the NSA for classified information. With both compression and encryption, this combination makes ZipBackup an ideal tool for storing backups offsite on systems such as DropBox or Google Drive. ZipBackup also provides a restoration panel where you can view and retrieve your previous backups. The tool lets you view or extract your files and folders as they were when the backup was made, regardless of the complex combination of full and incremental backups holding your data behind the scenes.
