Both do mostly the same thing with some differences. The biggest difference currently could be that WAL-E uses the PostgreSQL "archive_command" to send incremental backups (WAL files) in complete 16 megabyte chunks, whereas PGHoard uses real-time streaming with "pg_receivexlog", making the data loss window much smaller in case of a disaster.
