Glossary ======== .. glossary:: `Virtual machine`_ A virtual machine is a program that can execute an entire operating system inside an emulated hardware environment. `Container`_ A container is an isolated user space. Programs run directly on the host's kernel, but with limited access to the host resources. Datastore A place to store backups. A directory which contains the backup data. The current implementation is file-system based. `Rust`_ Rust is a new, fast and memory-efficient system programming language. It has no runtime or garbage collector. Rust’s rich type system and ownership model guarantee memory-safety and thread-safety. I can eliminate many classes of bugs at compile-time. `Sphinx`_ Is a tool that makes it easy to create intelligent and beautiful documentation. It was originally created for the documentation of the Python programming language. It has excellent facilities for the documentation of software projects in a range of languages. `reStructuredText`_ Is an easy-to-read, what-you-see-is-what-you-get plaintext markup syntax and parser system. `FUSE` Filesystem in Userspace (`FUSE `_) defines an interface which makes it possible to implement a filesystem in userspace as opposed to implementing it in the kernel. The fuse kernel driver handles filesystem requests and sends them to a userspace application. Remote A remote Proxmox Backup Server installation and credentials for a user on it. You can pull datastores from a remote to a local datastore in order to have redundant backups.
