WANdisco Unveils Results From Competitive Evaluation Vs. Cloudera BDR

WANdisco, Plc. to meet data challenges of secure storage, scalability and availability, announced the results of a recent competitive evaluation of company’s Fusion against Cloudera, Inc.‘s BDR (Backup and DR), covering both functionality and performance, undertaken by third party enterprise software testing firm Appvance, Inc.

In summary, Appvance recommended WANdisco Fusion, with its patented active-transactional replication technology over Cloudera BDR, for Hadoop data replication, backup and recovery.

“In our comparison tests of Cloudera BDR and WANdisco Fusion, we found WANdisco provides functionality, performance and availability not possible with Cloudera BDR,” said Frank Cohen, founder, Appvance. “WANdisco Fusion’s replication technology avoids BDR’s risk of data loss with automated DR after outages, and ensures availability even when entire data centers go offline. This is especially critical in regulated industries where production data and current backups must be available at all times.“

Key findings:

• WANdisco Fusion’s active-transactional replication with automated forward recovery avoids Cloudera BDR’s risk of data loss and extended downtime after outages. Cloudera BDR runs in batch and requires the replication job to be restarted from the beginning after an outage

• It replicated the same data volumes up to 90% faster than BDR without impacting the performance of other applications running on the clusters

• It performed full cluster backups up to 37% faster than BDR, used 40% less memory and allowed clusters to be available for other applications while the backup was running. BDR resource contention does not allow other applications to run during a backup

• Fusion ingests and replicates data at the same time, making it for streaming fast data applications that require replication, unlike BDR, which requires files to be written and closed

• It replicates data between Hadoop clusters running on any distribution, version and storage, including cloud storage. BDR only replicates data between clusters running specific versions of Cloudera’s CDH distribution of Hadoop, creating vendor lock-in.
