+Proxmox Backup Server consists of multiple components:
+
+* A server-daemon providing, among other things, a RESTful API, super-fast
+ asynchronous tasks, lightweight usage statistic collection, scheduling
+ events, strict separation of privileged and unprivileged execution
+ environments
+* A JavaScript management web interface
+* A management CLI tool for the server (`proxmox-backup-manager`)
+* A client CLI tool (`proxmox-backup-client`) to access the server easily from
+ any `Linux amd64` environment
+
+Aside from the web interface, most parts of Proxmox Backup Server are written in
+the Rust programming language.
+
+ "The Rust programming language helps you write faster, more reliable software.
+ High-level ergonomics and low-level control are often at odds in programming
+ language design; Rust challenges that conflict. Through balancing powerful
+ technical capacity and a great developer experience, Rust gives you the option
+ to control low-level details (such as memory usage) without all the hassle
+ traditionally associated with such control."
