BUP-SERVER()

bup-server - the server side of the bup client-server relationshipbup serverbup server is the server side of a remote bup session. If you use bup-split(1) or bup-save(1) with the -r option, they will ssh to the remote server and run bup server to receive the transmitted objects.

There is normally no reason to run bup server yourself.

smart
    In this mode, the server checks each incoming object against the idx files in its repository. If any object already exists, it tells the client about the idx file it was found in, allowing the client to download that idx and avoid sending duplicate data. This is bup-server's default mode.

dumb
    In this mode, the server will not check its local index before writing an object. To avoid writing duplicate objects, the server will tell the client to download all of its .idx files at the start of the session. This mode is useful on low powered server hardware (ie router/slow NAS).
