Idealstor is a a US vendor focused on disk to disk backup solutions. Their flagship product, iBac, offers a continuous data protection (CDP) approach and it’s available for Windows only.
In December 2008 the company extended the iBac capabilities to support VMware Infrastructure.
The new iBac Virtual Infrastructure Proxy (VIP) interacts with vCenter through the VMware Consolidated Backup (VCB) framework to backup virtual machines.
The original iBac licensing mode was based on the number of ESX hosts involved in the backup/recovery operation.
Two weeks ago Idealstor added a second licensing mode based just on the number of vCenters.
