Hi,
You can find answer of the questions on the VDP administration guide: http://pubs.vmware.com/vsphere-60/topic/com.vmware.ICbase/PDF/vmware-data-protection-administration-guide-61.pdf
Anyway, your answers are here:
- Yes, it can take backup from all guest OS that they are supported by vSphere.
- vSphere Data Protection (VDP) capacity requirements depend on a number of factors including:
- Number of protected virtual machines
- Amount of data contained in each protected virtual machine
- Types of data being backed up (OS files, documents, and databases, for example)
- Backup data retention period (daily, weekly, monthly, or yearly)
- Data change rates
NOTE Assuming average virtual machine sizes, data types, data change rates, and a retention policy of 30 days, 1 TB of VDP backup data capacity supports approximately 25 virtual machines
3. I couldn't find the feature on the guide!
