Super Benefits

Using Application-Aware, Global Source based deduplication technology, Druva inSync saves only a single copy of data duplicated across users.

With over 80% enterprise data duplicated across users in the form of duplicate emails, attachments or documents, this new approach makes backup highly efficient and guarantees 100% duplicate elimination while saving over 90% backup time and makes the best use of bandwidth and storage.

The new hierarchical caching reduces network roundtrips for deduplication; ensuring backups are leaner and faster.

Example

Consider for example an Outlook PST file. The PST file changes up to 5% even if the user closes outlook without any update. When backed up incrementally using backup software:

Traditional backup software will calculate block differential backup and may not be very successful in handling data for a large number of users.

A block level deduplication software would be better, but will fail to understand internal changes to the PST because of its complex on-disk structure.

inSync with its app-aware deduce algorithm understands 87 different message types in PST and backs up only the unique messages such as emails, attachments, calendar updates, etc. The approach guarantees 100% deduplication accuracy and optimal use of storage and bandwidth.

The new hierarchical caching, ensures that the file and sub-file duplicate checks are first made against a small cache at the client level before approaching the server. This reduces network roundtrips and makes backups faster.
