StoreBackup tries to accomplish the ``ideal backup'' and to solve the two problems: storage space and performance.
You can run it on a machine to store your backups to a local drive (or temporarily connected drive) or to a network mount (e.g., nfs, sshfs, cifs). This is the most efficient way. But you can also read the data from a machine which offers its data e.g., via cifs or nfs.
