I have two mongod instances without replication each having same collection name but different data.Now initialized replication between them.Secondary machine copies all data from primary machine and looses it’s original data.Can I recover original data present in secondary machine ?
Leaving aside the typos in the question (and any resentments they might generate), would you consider this the expected behavior? To me this sounds like a conflict in the setup and the database should error.

Arnold Matyasi posted 4 articles (with Clojure code, charts, and explanations) on how to analyze Google Analytics data locally with Clojure, Incanter, and MongoDB:
- Part 1: exporting data, setup, Clojure helper functions
- Part 2: first charts
- Part 3: grouping data
- Part 4: implementing weighted sort

I’ve spent most of my career in startups or small companies, that sometimes interacted with large corporation. I’ve also worked a couple of years within a large corporation. But I’ve never been through the transition from startup to corporation.
This is the phase 10gen, the company behind MongoDB, is in right now and they are hiring positions like VP of business development (Ed Albanese, ex-Cloudera), VP of corporate strategy (Matt Asay, ex-Nodeable, Alfresco, Canonical), and VP of services and product management (Ron Avnur, ex-MarkLogic).
In his first post for 10gen, Matt Asay cites 10gen president Max Schireson:
By far our most important competitor is Oracle. After that it’s Oracle, Oracle and Oracle. I see other NoSQL players such as DataStax [distributor of Apache’s Cassandra] and CouchDB as comrades in arms in the battle to persuade people that the answer does not have to be Oracle.
