I recently read an article by Cisco detailing the WAAS appliances capability to add addional deduplicaion to Data Domain replication traffic being forwarded across the WAN. After reading the aricle and speaking with my SE. He recommended a 674 in Application Acceleration mode vs the WAE 7341 in Replication Acceleration mode. The article also states Application Acceleration mode was used.
Why is Application Acceleration mode recommended over Replication Acceleration mode for this traffic?
I have a project requiring 15 - 20 GB / day of incremental backups to be replicated between 3 sites. The sites are 90 ~ 110ms apart and the links are around 20mbps at each site. Would a 674 in Application Acceleration mode really make a difference for the Data Domain replications?
You can configure TFO+LZ as the action. In the CM GUI it's called "TFO with LZ Compression". In the CLI, the command argument is optimize dre no compression lz.
