ZipSnapNG is an advanced, portable, multi-platform backup tool that requires no installation and is only 200KB in size. It offers features such as incremental backup, data deduplication, encryption, and configurable retention. It can be used through the command line or a graphical interface. Key features include the ability to create a new snapshot on each run, save or restore only the data slices of a file that have changed, and prevent storing duplicated data across directories.
