Much Ado About vStorage

By Shari Cravens

You’ve probably seen the February 2010 announcement from VMware heralding the end of life for its Consolidated Backup (VCB) framework – and their intention to rely on the new vStorage APIs for Data Protection (VDAP) in vSphere 4.1 once it’s released.

How does this impact you?  The new vStorage API will be beneficial for VMware backups as a whole (you can learn more about it on VMware’s blog.) But there are a number VMware backup methods that won’t be impacted in the short term.

HP will provide support for the new vStorage APIs for Data Protection (VDAP) in the current Data Protector software version after VMware releases vSphere 4.1 (find an overview of VMware data center products here), but it’s important to remember that most of the methods that HP Data Protector software supports for backing up VMware environments won’t be impacted. 

That includes:

  • Traditional online “guest” backups: the end-of-life announcement has no impact on customers who are performing virtual server backups by installing a Data Protector agent inside of their virtual machines.

  • Server-based snapshots: if you’re using Data Protector to execute server-based snapshots via VMware ESX 3.5 & 4.0, or vSphere environments (through version 4.0) you can continue to do so.

  • Array-based snapshots: Customers who are using Data Protector Zero Downtime Backup & Instant Recovery to execute array-based snapshots in ESX, ESXi, or vSphere environments (through version 4.0) can also continue to use this method. 

And – incidentally – Data Protector Zero Downtime Backup & Instant Recovery is still the only solution in the industry that addresses three of the biggest challenges associated with virtual server backup today – ensuring application-consistent backups, avoiding server performance impacts, and simplifying management – all from a single interface and without scripting.

Data Protector also currently supports VMware Consolidated Backup (VCB). While VMware will discontinue VCB, until that time customers who are using Data Protector to execute their VCB backups can continue to do so.

Dear Shari Cravens,

please go to work!

VCB is already "end of life" and Data Protector need VMware-vcb exe to work. You cannot support the vcb proxy, for example the setup, over next Windows Servers.

Also the VCB/DP-VCB not support "memory backup" and "FC restore".

The other "Data Protector" method are very bad because the copy need all disk space allocated. If we have one VM with 1TB of VDISK, Data Protector copy the whole space... ridiculous!

We are skeptical of what we are reading....

vSphere 4.1 is released When will HP Data Protector support VADP? VCB is end of life and ESXi does not support console agents.
