The appliances, which replace Revinetix's Sentio appliances, consist of a virtual machine implementation and six hardware-based appliances that range in capacity from 1 TB to 132 TB of storage and from 1U (1.75 inches) to 9U (15.75 inches) in height.
All the appliances except the Software Virtual Appliance connect to the network with two to six 1-Gbps Ethernet connections. With the exception of the Software Virtual Appliance and the EverSync 1000, the appliances have two 10-GbE connections.

All the appliances feature file-level deduplication and all but the EverSync 1000 feature block-level deduplication. All seven appliances support virtualization and, with the exception of the EverSync 1000, support for instant virtual machine restore and replication.
Backup and restore speed over 1 GbE ranges from 150 GB/hour to as much as 1 TB/hour. If a 10-GbE LAN exists, backup and restore speed increases to 700 GB/hour to as much as 1 TB/hour.
The five largest appliances--the EverSync 1500, 2000, 2500, 4500, and 9500--support solid-state drives ranging from 120 GB to 480 GB in capacity.
EverSync has designed its products for specific uses. The Software Virtual Appliance and EverSync 1500, 2500, 4500, and 9500 are intended for use in virtualized environments. The EverSync 1000, 1500, 2000, and 2500 are designed primarily as backup appliances. Finally, the 2000, 2500, 4500, and 9500 are intended as full-data-protection solutions.
On the virtualization front, Eversync supports both VMware and Hyper-V. It is agentless and allows simultaneous backup of virtual as well as physical machines from a single management console. Microsoft SQL Server and Exchange backups are supported, as is the discovery and tracking of active virtual machines when they migrate to another type of storage. File-level restorations directly from the "golden image" VMDK file are possible without having to restore the virtual machine first. And application-level restores directly from the VMDK are also possible through integration with the VMware Volume ShadowCopy Services Writer for Microsoft applications.
Further, there is support for inline deduplication for VMware environments, in which a snapshot is taken of the previous version and instant restoration of files occurs in virtual or physical environments. Eversync supports the VMware APIs for Data Protection, which allow backups of unused sections of VMDK files and differential or incremental backups of virtual machines.
In the area of network performance, Eversync now supports network interface card bonding or teaming, which allows the aggregation of multiple GbE ports to create larger pipes.
Finally, Eversync provides remote management via iPads, iPhones, and Android devices, including the Kindle Fire.
The hardware appliances are available now and range in pricing from $11,300 for the Eversync 1000, $17,000 for the 1500, and $32,000 for the 2500. The Software Virtual Appliance is expected to be available in 60 days.

IT can't maintain absolute control over highly virtualized infrastructures. Instituting a smart role-based control strategy to decentralize management can empower business units to prioritize their own data assets while freeing IT to focus on the next big project.
