   6    `Virtual machine`_
   7
   8       A virtual machine is a program that can execute an entire
   9       operating system inside an emulated hardware environment.
  10
  11    `Container`_
  12
  13       A container is an isolated user space. Programs run directly on
  14       the host's kernel, but with limited access to the host resources.
  15
  16    Datastore
  17
  18       A place to store backups. A directory which contains the backup data.
  19       The current implemenation is file-system based.
  20
  21    `Rust`_
  22
  23       Rust is a new, fast and memory-efficient system programming
  24       language. It has no runtime or garbage collector. Rust’s rich type
  25       system and ownership model guarantee memory-safety and
  26       thread-safety. I can eliminate many classes of bugs
  27       at compile-time.
  28
  29    `Sphinx`_
  30
  31       Is a tool that makes it easy to create intelligent and
  32       beautiful documentation. It was originally created for the
  33       documentation of the Python programming language. It has excellent facilities for the
  34       documentation of software projects in a range of languages.
  35
  36    `reStructuredText`_
  37
  38       Is an easy-to-read, what-you-see-is-what-you-get plaintext
  39       markup syntax and parser system.
  40
  41    `FUSE`
  42
  43       Filesystem in Userspace (`FUSE <https://en.wikipedia.org/wiki/Filesystem_in_Userspace>`_)
  44       defines an interface which makes it possible to implement a filesystem in
  45       userspace as opposed to implementing it in the kernel. The fuse
  46       kernel driver handles filesystem requests and sends them to a
  47       userspace application.
  48
  49    Remote
  50
  51       A remote Proxmox Backup Server installation and credentials for a user on it.
  52       You can pull datastores from a remote to a local datastore in order to
  53       have redundant backups.
  54
  55    Schedule
  56
  57       Certain tasks, for example pruning and garbage collection, need to be
  58       performed on a regular basis. Proxmox Backup Server uses a subset of the
  59       `systemd Time and Date Specification
  60       <https://www.freedesktop.org/software/systemd/man/systemd.time.html#>`_.
  61       The subset currently supports time of day specifications and weekdays, in
  62       addition to the shorthand expressions 'minutely', 'hourly', 'daily'.
  63       There is no support for specifying timezones, the tasks are run in the
  64       timezone configured on the server.
