The process I use that leads to the warnings is simple:

I use pg_controldata to determine the current checkpoint WAL location
of the standby server. I ensure I have this WAL file and all newer
WALs. I backup all files under the standby's database cluster
directory, including all tablespaces, which are soft linked. I restore
the database cluster directory to its new location and create soft
links in pg_tblspc to point to the proper tablespace directories just
backed up. I create the pg_xlog directory containing an archive_status
directory.

This seems not exactly per spec. Why are you not using pg_start_backup
and pg_stop_backup around the copying of the database files?

I'm trying to take a base backup from the standby server in archive recovery mode. I don't believe it's possible to connect to it to issue pg_start_backup/pg_stop_backup.
