Need some explanation about BE Instant Recovery feature

Hello,

I use BE2012 for backing-up vSphere infrastructure and recently have known about feature named "Instant Recovery". But I found completly different explanation of this feature in BE and NetBackup guides:

• BE admin guide talk about possibility to convert physical server backup into virtual machine with subsequent restore;
• NetBackup admin guide contain some words about "zero-time" VM recovery using NFS to mount VM directly from backup to desired ESXi. And it's possible to move restored VM to production storage using VMware vMotion.

So I would like to understand - does Backup Exec have NFS-powered Instant Recovery for restoring VM? Or "Instant Recovery" is just a similar name with NetBackup feature, but completely different by sense?

Thanks a lot!
