Some question about snapshot and apis.

[NicolasBourbaki]

Hi all,

I have some questions about taking snapshot on VMWare.

I have read some books, and still don't know the relation between VIX APIs, vSphere APIs and vStorage APIs?

Another question is what is the difference between VDR, VDP and VCB?

I am about to integrate snapshot into my storage device.

Thanks for your reading and hope for some replies.

Hi,

This link - Virtual Disk Development Kit FAQ should answer some of your questions.

See this thread - VDR, VDP, VCB - Demystifying Backup Options for your other question

Thanks for your reference information.

So,

vSphere APIs is a web service and XML interface like vSphere Client?

vStorage APIs is a framework, and every backup service or service rely on it? Include the other third-party software like NetApp or EMC?

Thanks for your reply.

You are right.

vStorage API - VMware vSphere Storage APIs for Third Party Integration | United States .

For example:- VMware VDP product uses vStorage API for Data Protection

Even I use NetApp or EMC, they still are based on vStorage APIs.

Due to this, if I want to integrate snapshot into my storage product, I should focus on vStorage APIs, right?
