WAL archiving from a standby backup strategy Postgresql 9.3 I am trying to figure out if wal archiving from a standby is possible and a viable option for a backup strategy on Postgresql 9.3. 

The idea is to be able to take regular base backups and wal archives from a standby server in a remote DR site. 

Unfortunately, the archive_command functionality is not available while the server is in standby_mode mode so I am wandering if the wal archiving could be done successfully using alternative ways like rsync, lsyncd etc.

Has anyone tried to this path can you share your experience?
Postgresql provides a pg_receivexlog utility that can be used instead of archive_command to do wal log archiving. 

From the Documentation:


  pg_receivexlog is used to stream transaction log from a running PostgreSQL cluster. The transaction log is streamed using the streaming replication protocol, and is written to a local directory of files. This directory can be used as the archive location for doing a restore using point-in-time recovery
