DAR is a powerful command-line backup and archiving tool that offers a wide range of features. It uses selective compression, which means that it does not compress files that are already compressed.

In addition, it provides strong encryption to ensure the security of your archived data. DAR also has the ability to split an archive into different files of a specified size, making it easy to manage large archives.

One of the key advantages of DAR is its support for on-the-fly hashing. This means that it can calculate and verify the integrity of your data as it is being archived, ensuring that no data corruption occurs during the process.

DAR also supports differential backup, allowing you to only backup the changes that have occurred since the last backup, saving both time and storage space.

Not only does DAR support local storage options, but it also offers support for remote cloud storage. It can utilize the FTP and SFTP protocols to backup your data to a remote cloud storage provider, giving you the flexibility to choose where your data is stored.

Another impressive feature of DAR is its ability to quickly restore individual files from a large, compressed, and encrypted archive. Even if the archive is located on a remote cloud storage, DAR only fetches the necessary data to perform the restoration, ensuring efficient and speedy file retrieval.

When it comes to preserving your data, DAR does an excellent job. It saves all UNIX inode types and takes care of hard links and sparse files. It is also capable of handling Extended Attributes, such as MacOS X file forks, Linux ACL, SELinux tags, and user attributes. In addition, DAR supports some Filesystem Specific Attributes, including Linux ext2/3/4 and Mac OS X HFS+.

With its comprehensive set of features and robust capabilities, DAR is a reliable choice for your backup and archiving needs.
