In the multi single server setup, the zarafa-archiver in configured in such a way that the archive resides on another Zarafa server, which is not part of the same cluster as the primary server. Usually this means that none of the Zarafa servers is configured for multi-server usage.

The advantage of this setup is that no multi server license is required. This comes at a cost: stubs are not supported and the archive store can’t be added as a shared store in an existing profile.

Because the archive server is not known by the primary server, the archive server must be specified when the archive is attached to a user store.

zarafa-archiver -u user --attach-to archive --archive-server https://archive.zarafa.com:237/zarafa

This attaches the user user to the store called archive on the server that can be connected to through https://archive.zarafa.com:237/zarafa.
