Apologies to everyone who has been waiting. On Wednesday morning we will have a beta 5.3 firmware version available to customers participating in beta testing in this forum. The following functionality will be available in that firmware:
SQL 2012 Backup and Restore. With the new agent, Barracuda Backup will be interfacing with VSS instead of the legacy VDI connector.
Exchange 2013 - both with the backup agent and message level backup.
Server 2012 - with support for ReFS and deduplicated storage.
Hyper-V 2012 & Cluster Shared Volume
The new Linux agent will be incorporated into this build as well, though the functionality will not be significantly different than the agent only release we made available to customers on this list.
If you would like to try this new functionality, please go ahead and post to the forum and let us know. We'll contact you directly and get you the new firmware.
Please contact me for the new 5.3 firmware so we have Exchange 2013 support.
