The VIRTUMANIA continues with Episode 2! Rick Vanover joins Marc and I again along with very special guest Jason Boche, the Virtualization Evangelist, for a recorded discussion about DR options in virtualized environments. The following is the podcast summary:

VIRTUMANIA Podcast Episode 2 – Virtulization Makes DR Easy. Rich Brambley (@rbrambley) of VMETC and Marc Farley (@3parfarley) of 3Par and StorageRap.com with guests and Rick Vanover (@rickvanover) of RickVanover.com and Jason Boche (@jasonboche) of Boche.net/blog. This week’s episode includes discussion about how virtualization has changed disaster recovery and site failover, explores various virtual machine backup and replication products, compares storage mirroring to purely physical solutions in the past, and thinks about DR technologies in the future. Thanks to Greg Knieriemen (@knieriemen) of Chi Corporation for this Infosmack Production.

Before, between, and after the important stuff we also have some fun with Virtumania Bucks, the ongoing danger of nipples in the data center (yes, we go there again!), and a new nickname for Greg Knieriemen.

I received an email today from VMware addressed to all customers about the end of availability for VMware Consolidated Backup (VCB). Quoting from the beginning of the communication but not the entire message, it reads:

“The purpose of this letter is to inform you of our vSphere backup product strategy, ongoing enhancements, and end of availability plans for VMware Consolidated Backup.

VMware Backup Product Strategy
VMware released vStorage APIs for Data Protection (VADP) with the vSphere 4.0 release in May, 2009. VADP is the next generation of VMware’s backup framework. We have also been working with several backup partners to integrate VADP into their solutions to make backup of vSphere Virtual Machines fast, efficient and easy to deploy compared to VCB and other backup solutions. Several of our major backup partners have already released VADP integrated backup products and we expect most of the major backup partners to have VADP integrated backup software by the upcoming feature release of the vSphere platform in 2010.

Future Product Licensing
Given the strong interest and adoption of VADP by our backup eco-system and the benefits offered by VADP compared to VMware Consolidated Backup (VCB), we are announcing the End of Availability for VCB starting with next vSphere feature release in 2010. Starting with the next vSphere platform feature release, VCB will be removed from vSphere platform. VADP integrated backup products (including VMware Data Recovery) will be the recommended option for efficient backup and restoration of vSphere Virtual Machines. This will allow us to focus new value added feature development on VADP instead of two backup frameworks (VCB and VADP).”

It has to be the most common question for those implementing a new virtual infrastructure (VI)  – “how do we back up our virtual machines?” There are certainly plenty of choices. A company could stay with the (most commonly found in physical environments) system of agent based tape backups, implement VMware Consolidated Backup (VCB), implement a third party disk to disk product, or rely on SAN array snapshots. Most likely they will end up with a hybrid solution involving many of these choices. There is not an easy and consistent answer. It’s a company by company decision.

Luckily several posts have recently been published on TechTarget.com sites SearchDataBackup and SearchVMware that tackle the topic of comparing the software based VMware VM  backup alternatives and offer a lot of information for those evaluating the choices. I thought I would summarize these links since they have caught my attention over the last several weeks. Finally I link to a post about the unique advantages of SAN array backups for a hardware based backup comparison.

Readers should be aware that VMware’s Data Recovery (vDR) product has been updated since the posts linked in this summary were written. Although there are some new features introduced, the implementation requirements have not changed and therefore the content of these posts remain relevant.

Although I’ve covered what VI admins need to know about VCB in the past, I am not covering the product in this post. Check some of my other VCB posts for more information. Read the rest of this entry »

The VMGuy has the scoop on all the VMware releases tonight! VMware has also made available an updated version of the GUI based virtual machine (VM) backup and restore plugin for vCenter 4, VMware Data Recovery 1.1 (VDR). Download it here and check the check the Release Notes here.

VMware is saying VDR has improved performance and progress information during intgregity checks, enhanced CIFS support, and that the previous experimental support status for File Level Restores of Windows VMs has been elevated to full support.

Although I could find no mention of it on the VDR web page, the data sheet, or in the new Release Notes, VDR was originally targeted for virtual infrastructure that hosted up to 100 VMs. I’m not sure if this VMware support limitation is still in effect or not.

Still, combined with the already built in de-duplication of VDR VM backups, SMBs have a great VCB alternative that continues to improve.

One of the Solutions Exchange theater presentations I sat through was at the PHD Technologies booth. I watched a presentation on their latest product release, esXpress 3.6. Backing up virtual machines (VMs) is a constant and important concern of virtualization administrators, and esXpress offers a unique, award winning alternative. Up to 16 simultaneous live backups or restores per ESX host is possible without impacting ESX Service Console resources and without configuration of additional VCB (VMware Consolidated Backup) infrastructure.

The secret to esXpress is the use of VBAs (Virtual Backup Appliances). A VBA is a prebuilt software solution running on it’s own Linux OS that runs as a VM along with the production VMs on each ESX 3.x /4.x host. There are no agents to install in the VMs being backed up, nor any dependency on APIs. A single Configuration Virtual Appliance must run somewhere in the environment to provide a esXpress management console that enforces global configuration settings across all the backup VBAs. A fourth VM appliance can also be added to the solution to serve as a deduplicated, backup destination target VM. Other possible backup destinations are SMB, SSH, FTP, and VMFS repositories.

Looking for some good information about backing up VMware virtual machines (VMs)? Researching or planning for VMware Consolidated Backup (VCB) or third party solutions like PHDVirtual esXpress that enhance the VCB functionality? PCPRO Magazine has combined an article I wrote last October with a related work from author/blogger/VMTN Guru Eric Siebert into a free E-guide titled What You Need to Know about Virtual Machine Backup that is worth the download. After a quick registration with Bitpipe.com, (Bitpipe and SearchDataBackup.com are both TechTarget.com sites) you’ll have access to a 9 page PDF that is an easy read full of useful, real world VM backup implementation advice.

If you did not know already, Bitpipe provides access to great virtualization industry articles and whitepapers on as well as many other technologies. I subscribe and get an email notification from Bitpipe full of great research links daily.

Here is more about the E-Guide from the download page: Read the rest of this entry »

New in the latest version of ESX 3.5 is an experimental Service Console script called the VMDK Recovery Tool. Since it’s Console based, it’s not available in ESXi. The Update 3 Release Notes say the following about it:

Experimental Support for the VMDK Recovery Tool — This release adds support for the VMDK Recovery tool, a script intended to help customers to recover VMFS/vmdk data stores from accidental deletion of VMFS/vmdk data store or physical disk corruption. For more information, see VMDK Recovery Tool (ESX 3.5 Update 3) ( KB 1007243).

Use the VMDK Recovery Tool to:

Create a “block list” of your VMDK files. The block list file is a plain text file that keeps a record of all VMDKs of the virtual machines.

Recover VMDK files if they become deleted, or if the VMFS datastore gets deleted or corrupted.

Undelete VMDKs? Recover corrupted or deleted VMFS data stores? Reading KB 1007243 a little further reveals you can back up and restore VMs too – either specify which one you want to back up or pick all the registered VMs on the host. The script asks you to specify the directory path to use for saving backups and the destination path for restoring from backups.

Sounds to me like this script could become a “super VCB” without the extra server requirements? It seems much simpler anyways. It will be interesting to see how this script is developed and exactly how much disk space the block list and backup files consume.
