After keeping it beta for more than a month, Druvaa on June 26th announced the general availability of Druvaa inSync v2.0. The idea behind v2.0 is fast and bandwidth/storage efficient backup. The much awaited release, brings two very interesting and unique features -
1. SendUnique - 10x Faster backup with 90% reduction in storage and bandwidth utilization.
Almost 80% of PC data (emails/docs) within an enterprise is common between users. SendUnique technology fingerprints the user’s backup set to send only one copy of data (emails/docs) common between different users to the backup server. This speeds up backup by almost 10 times and cut bandwidth usage by 90%.
2. Eternity - Never Lose a file. Ever.
Timeline based, from-the-past restore. Enables ultimate protection against data loss or virus attacks.

The Gartner Report (here) says storage data de-duplication and virtualization are two main technologies driving innovation in storage management software this year. This makes sense, considering the fact that corporate data is increasing at a whooping 60% annual rate. (Microsoft Report says here).
Server Backup
Data is very rarely common between production servers of different types. Its not difficult to imagine that Exchange email server may not have same content as Oracle database server. But data is largely duplicate within file-servers, exchange server and say a bunch of ERP servers (development and test). This duplication creates potential bottlenecks for bandwidth and storage used for backup.
Existing players have offered two solutions to this problem -
- Traditional single-instancing at backup server to filter out common content e.g Microsoft Single Instance Service (in Data center edition). This saves the just storage cost, depending upon at what level to filter commonalities - file / block / byte. A big player in this space is Data-Domain. These solutions don’t have a client component, they just save storage space.
- New innovative solutions like Avamar (now with EMC) and PureDisk (now with Veritas) which try filter content at backup server level before the data goes to the (remote) store. This makes these solutions much better suited for remote-office backups. They save bandwidth and storage.
But, there are two unsolved problems with both these approaches as well ( Which also, explains a poor response for these products in the market )-
- most of the times simple block checksum matching fails to figure out common data, as it may not fall on block boundaries . Eg. if you insert a simple byte in a file, the whole file changes and all the blocks shift. And the block checksum approach fails.
- Checksum calculation is very costly and makes backups CPU exhaustive.
- These approaches are targeting storage cost, not time/bandwidth which is more critical.
PC Backups
The problem is much more complex at PC level, as duplicated data is distributed among users and is as high as 90% in some cases. Emails / documents and similar file formats create large pool of duplicate data between users.
Also, since 50% of PC backup is mainly large email files, this is problem is particularly difficult to solve using simple file based de-duplication techniches used by servers.
Druvaa inSync v2.0 uses a on-wire (distributed) de-duplication technique which senses duplicate data before the backup starts and hences skips it from the backup. This is transparent to the user, all he notices is a 10 times boost in backup speed with over 90% reduction in bandwidth and storage usage.
How it works
This technology creates and maintains a Global “Single Instance” File System at backup server. Each time a user wants to backup a file, the insync clients prepares a file-fingerprint (using linear polynomial based hash) and compares it with the server. After the server sends a response, the backup happens only for the “unique” data within the file.
The (patent pending) advance file-fingerprinting makes it computationally very easy to filter common content like - same paragraphs in different documents, a same CCed email, media rich corporate presentations etc. This cuts down time for backup by 10 times and reduces bandwidth and storage utilization by 90%.
Other Interesting Features
Another good use of the Gobal Single Instance File System is - Continuous Data protection. The user after starting the restore can see how his files changes over time. Which gives him an option to restore point-in-time data from any point in the past. The marketing name for the feature is - “Eternity. Never lose a file. Ever.” A long name, but serves its meaning 
Business Opportunities
The same technology/product can be stripped down to backup PDAs and scaled up to backup servers. A good use case would be to reduce time for backup of bunch of related remote servers.

Druvaa announces the availability of Druvaa inSync 2.0 Beta. The idea behind v2.0 is fast and bandwidth/storage efficient backup. The much awaited release, brings four very interesting and unique features -
1. SendUnique - Enterprise wide on-wire data de-duplication. Almost 80% of PC data (emails/docs) within an enterprise is common between users. SendUnique technology fingerprints the user’s backup set to send only one copy of data (emails/docs) common between different users to the backup server. This speeds up backup by almost 10 times and cut bandwidth usage by 90%.
2. Eternity - Never Loose a file. Ever. Timeline based, from-the-past restore. Enables ultimate protection against data loss or virus attacks.
3. NetworkSense - Automatic network sensing and prioritization. Allocates a user defined percentage of bandwidth for backups.
4. TrueSecure - Client triggered secure backups. 256 byte network (SSL) and 256 bit (AES) storage encryption.

We still couldn’t figure out what makes the traditional backups so slow and resource hungry.
But, we benchmarked insync against normal network copy using a HP dual core machine configured for 50 users. Here are the results -
You can download the PDF (117KB) and other related documents from http://www.druvaa.com/download/insync.html
Should the results differ for a larger set of users ? Looks difficult, but would soon try and publish (upcoming) version 2.0 benchmarks with larger set of users.
