Release 8.2 - Accelerated Adaptive Deduplication



With the general availability of Unitrends software release 8.2, Unitrends introduces accelerated adaptive deduplication.

Accelerated adaptive deduplication removes duplicate data before it is stored on the backup appliance, reducing the amount of landing zone space required for backups. This decreases required storage capacity and increases on‐ appliance retention. For file‐level backups, accelerated adaptive deduplication removes duplicate data as backups run, reducing the amount of data written to the backup appliance.

For VMware backups, accelerated adaptive deduplication removes duplicate blocks client‐side, before sending data over the network to the backup appliance.
Benefits include consolidation ratios exceeding 20:1 and scalability beyond 100TB of protected capacity.

With the release of accelerated adaptive deduplication, Unitrends introduces a suggested backup size for our Recovery-Series appliances.  This is a number that, when adhered to, should allow an average of at least 30 days or more of retention. When data size grows beyond the capacity of a backup appliance, Unitrends cloud can be used to meet retention needs.

Synthetic full backups are created from incrementals to create recovery points for faster restores. With software release 8.2, incrementals are synthesized in‐line as backups run. This method frees critical backup appliance resources and ensures consistently fast recovery, backup, replication, and archiving times. With this method, synthetic backups are created 5‐10 times faster.


Accelerated adaptive deduplication is available on S‐series appliances (Recovery‐nnnS models) and new UEB deployments. These enhancements are not applicable to older appliances that are upgraded to version 8.2.

S-series appliances must be imaged with software version 8.2 to use accelerated adaptive deduplication.

In-line synthesis requires an appliance to be using accelerated adaptive deduplication.

Post-process deduplication will be used for certain data types, including Oracle databases, Microsoft SharePoint, NDMP, SQL 2000 and Novell OES/Netware.

In-line synthesis is not available for application backups.
