AFAIK the directory structure of the base backups is the same as a running server, only the pg_xlog directory is empty.
So, maybe it would be possible to hardlink that, except the pg_xlog, and then restore the WAL in a "real" pg_xlog fiolder with "barman get-wal ..."And then i could backup that to the off-site server.
Only, how do i know which WAL-id's to restore?
