The \fBknife download\fP subcommand is used to download roles, cookbooks, environments, nodes, and data bags from the Chef server to the current working directory. It can be used to back up data on the Chef server, inspect the state of one or more files, or to extract out\-of\-process changes users may have made to files on the Chef server, such as if a user made a change that bypassed version source control. This subcommand is often used in conjunction with \fBknife diff\fP, which can be used to see exactly what changes will be downloaded, and then \fBknife upload\fP, which does the opposite of \fBknife download\fP\&.
