Druvaa Dusts For Fingerprints to Save Bandwidth and Storage

Druvaa, an enterprise data backup solutions provider, recently launched their new product, Druvaa inSync. InSync is an enterprise PC backup system, that boasts 10x faster data backup while reducing 90% of the bandwidth and storage utilization.

InSync is based around a new technology from Druvaa called SendUnique, that creates a fingerprint for each file to prevent duplication. When 80% of enterprise files and communication are common between users, de-duplication is an important consideration. SendUnique uses a Single Instance File System on the backup server, and compares the file fingerprints during the backup to the files already on the server to determine if it’s unique data. This works especially well for remote notebook computer users who have essentially the same data on multiple computers. There is also a timeline-based system to track changes to existing files in order to restore point-in-time data from any specific time.

Some other new solutions have attempted to fix these problems, but in very different ways. Microsoft Single Instance Service, and Data-Domain both attempt to filter out similar data through traditional single-instancing at backup server level. Newer solutions like Avamar (EMC) and PureDisk (Veritas, a division of Symantec), filter content at the backup-server level before sending data to a remote store. All of these solutions save bandwidth and storage, but the calculations weigh down the CPU and simple block checksum matching often fails to interpret common data.

Druvaa is a new startup based in India, and has received $250,000 in a seed round from the Indian Angel Network in January 2008. They recently were awarded the Indian Entrepreneurial Challenge 2008 Award, chosen out of 8 finalists and 140 applications.
