What I mean under “Integration”.
Backup software should have ability to backup and restore next type of data:
vCloud vApps (don’t mix up with vCenter vApps it`is completely different things)
vCloud VMs (VMs provisioned by vCloud)
All this objects you may see under vCenter Server tree, but it doesn`t mean, that integration is means that this is enough to include vCenter Folder into policy, backup software must work closer with vCloud Director to show objects exactly like it shown there.
Restore is means restore in the vCloud environment, it is not enough to restore VMs in vCenter environment. Good feature is to restore in some folder, for example where backup client works.
Transport: Because organizations may have their own network topology it is necessary to provide ability backup and restore data using LAN-free technologies like SAN and Hot-add.
Security: It would be nice if we may create user and give him ability to see only those VMs that belongs to specific organization.
