CIFS Peak Performance – Multi Stream Ingest



By upgrading, immediate performance benefits are experienced including Rapid CIFS acceleration abilities with Veeam Backup & Replication software.

DR Rapid is an acceleration suite of plugins which includes Rapid CIFS.  Rapid CIFS allows for Veeam Backup & Replication and other third party backup software to minimize the network as a backup bottleneck by deduplicating at the source (Before it hits the LAN).  In Veaam’s case, the source side deduplication occurs at the proxy server. 

By upgrading to DR OS, Veeam Backup & Recovery using Rapid CIFS could experience up to a 31.3% performance improvement.
