Rethinking Backup with Veeam

I am a worry wart when it comes to backing up data. For my critical systems, I never trust a single backup method, but rather I implement several different strategies for backup and disaster recovery. For the past two years, one of those methods has been using Veeam Backup and Recovery.

Traditionally, Veeam has been a product to backup virtual machines (VMs) hosted on either Hyper-V or VMware hosts. They specialized in backing up the entire VM to disk quickly and easily using encryption and/or deduplication. Daily backups are incremental, as they only backup the bits of virtual disks that actually changed since the last backup. This makes incremental backups very quick, and requires very little disk space compared to comparable solutions. The product also made it very easy to restore an entire VM to any host running the same hypervisor platform.

Export a Running Virtual Machine Using PowerShell

Exporting a Hyper-V VM (virtual machine) creates a full copy of that VM. This can be used as an easy way to create an ad-hoc backup or an archive. An export can also contain all of the existing checkpoints that exist, so it is a really helpful tool during deployments, migrations, and upgrades. Read the rest of this entry »

Importing & Exporting Hyper-V VMs in Windows Server 2012 R2

HyperV_LogoThough often a less frequently used feature of Hyper-V, the import and export functions offer some very useful benefits.  In Windows Server 2012 R2 these benefits get even better.  I will explain how this functionality works, and why it is useful.  I’ll also discuss how these functions are very different from the commonly used checkpoints in Hyper-V.

Windows Server 2012 Feature: Share Nothing Live Migration in Hyper-V

Live Migration is the process of moving a virtual machine (VM) from one Hyper-V virtualization host to another Hyper-V host without any perceived downtime of the VM being moved. Read the rest of this entry »

Windows Server 2012 R2 (Blue) Preview Available for Download

Microsoft has released the preview of Windows Server 2012 R2 to the public. This is available for download for users with a Live ID at Microsoft’s Windows Server 2012 Preview site.

If you’re not familiar with Microsoft’s “Preview Releases”, then let me explain a little. The preview is not a finished copy, but rather a beta version which contains most (if not all) of the features and improvements we should expect to see in the final version for GA (general availability).

Getting Better Performance for Your Virtual Machines

As a seasoned virtualization expert (mostly with Hyper-V environments), I totally agree with the concept of building your VMs (virtual machines) and virtualization hosts to meet a particular need.

Often, I talk to SQL DBAs (database administrators) or Exchange administrators who swear that these platforms can NEVER be virtualized. This line of thinking is so wrong that Microsoft itself has bet their business around it (e.g., Office 365, Microsoft.com, etc.).

The most important piece of advice I give to virtualization newcomers is to treat a VM like you would a physical server. If a physical Exchange server needs 16GBs of memory and 4 CPUs, then building a VM with only a single virtual processor and 2GB of memory is going to result in a bad user experience, obviously.

HDD (hard disk drive) performance is always a concern with VMs. If you are creating a VM to run a disk intensive SQL server, then you will certainly care about your disk performance. With the more recent versions of Hyper-V, there is little noticeable performance reduction when choosing dynamically expanding VHD (virtual hard disk) vs. using a fixed size VHD. The big downside is that you now have to monitor and manage your storage on the host since your VMs can quickly consume physical space.

If extra disk performance is really needed, there is an option of using a pass-through disk. Pass-through disks will use an unused volume on the physical Hyper-V host as if that volume were its own. With pass-through disks you’ll get true hardware-level performance. The downside is that your VM is now tied to this physical storage making it difficult (or impossible) to migrate to a different host… so plan accordingly.

Windows Server 2012 New Feature: Hyper-V Replica for Failover

For mission critical systems, we often want to try to achieve the highest level of up time as possible, and the best disaster recovery strategy.  Often this involves expensive software which replicates servers or data for failover purposes.  This means Read the rest of this entry »

Windows Server 2012 New Feature: Large Disk Support for Hyper-V

One of the biggest limitations of Hyper-V in Windows Server 2008 R2 was that it didn’t support storing a Virtual Hard Disk (VHD) on physical disks larger than 2 TB.  This was actually due to the sector size of the physical disk which was supported by Hyper-V.  Larger disks tended to use 4096-byte sectors (also known as 4k sectors).   Read the rest of this entry »

Windows Server 2012 New Feature: Store Hyper-V VHDs in a SMB 3.0 Share

When building high-performance Hyper-V host servers for a production environment, we often buy high-end servers with lots or memory and fast SAS (Serial Attached SCSI) or SSD (Solid State) drives.  These drives are fast but usually expensive, especially after adding in RAID redundancies.

Introducing Hyper-V Quick Migration

In the Hyper-V world, lots of us talk about Live Migration. That is where a virtual machine (VM) is moved from one host to another with no perceived downtime. The caveat is that both hosts need be configured to use the same shared storage (such as a SAN or external drive array). Read the rest of this entry »
