Introduction John Kelbley  Senior Technical Product Manager with Microsoft’s Platform Tech Strategy Team (Redmond-based group)  Field-based “corporate” resource focused on customer and partner engagement for new server technology  Server Virtualization  High Performance Computing (HPC)

Agenda  Introductions  DR Benefits of Virtualization  Virtualization Backup & Recovery Challenges  Backup and Recovery “On the Cheap”  Export / Import  Windows Server Backup (WSB)  Scripted Diskshadow Backup  Q & A

DR Benefits of Virtualization  Separates application from at risk physical hardware  Move “that scary server in the corner that we don’t have the install CDs for anymore” to a VM  Perpetuates a key business function  Encapsulating a server in a VM let you easily  Back up / restore  Migrate  Availability (failover clustering)  Hardware maintenance  Performance

DR Benefits of Virtualization  Application Backups Where None Were Possible  How do you backup 10 year old multi- dimensional database?  Shut down services, copy files, start services, run backup (or often NOT AT ALL!)  How do you backup your Linux hosts? (many admins don’t!)  High Availability Where None was possible  Cluster physical hosts  Hyper-V – Quick Migration / Live Migration

Can You Back Up Virtualized Systems Safely? ( article discussing Vmware Consolidated Backup)  “it's not something that's easy to use and implement…you have to do the integration to make it work.”  "It's difficult to just use …you have to write a lot of scripts and requires a lot of maintenance…that just adds another level of management to the process.“  Companies rushing to virtualize …find that backup and restore could be a problem due to its extensive use of scripting.

How Do You Backup Your VMs?  With VMware (and other virtualization stacks) agents inside VMs are common  Host backups can be hard to “integrate”  Agents insdie VMs does NOT provide you the benefit of encapsulation!

Hyper-V Comes With Backup!  Because Hyper-V is integrated with Windows Server 2008, it can take advantage of integrated features:  File management tools and commands you already know!  Windows Server Backup (WSB)  Volume Shadow Copy Service (VSS)

Export / Import  Integrated into Hyper-V is the ability to Export a VM’s configuration and Disk (VHD files)  VM must be off or “saved”  Packages up:  Configuration (.XML)  Disk (.VHD)  Memory if saved (.VSV)

Why Not Just Use Export?  VM must be stopped (down time)  Duplicates virtual machine every time (space)  Does not work for pass through disk / or “child” mounted iSCSI (can’t capture all disks)

Windows Server Backup  Integrated with Windows Server 2008 (Replacement for NTBackup)  Volume Shadow Copy (VSS) Aware  Integrated scheduling features

WSB Limitations  Must register Hyper-V VSS Writer first!  reg add "HKLM\Software\Microsoft\windows nt\currentversion\WindowsServerBackup\Application Support\{66841CD4- 6DED-4F4B-8F17-FD23F8DDC3DE}"  reg add "HKLM\Software\Microsoft\windows nt\currentversion\WindowsServerBackup\Application Support\{66841CD4- 6DED-4F4B-8F17-FD23F8DDC3DE}" /v "Application Identifier" /t REG_SZ /d Hyper-v  Scheduled backups require a dedicated Volume (will be formatted!) - manual backups do not need their own vol  Restores ALL VMs from backup…cannot select individual VMs

Backup and Recovery  “DiskShadow” backup can work as well  Call Diskshadow.exe with a pre-defined script (example: diskshadow -s HyperVBackup.txt )

HyperVBackup.txt (unsupported) set context persistent set metadata C:\backup.cab set verbose on begin backup add volume C: alias ConfigVolume #The GUID of the Hyper-V Writer writer verify {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} create EXPOSE %ConfigVolume% Y: EXEC c:\HypervBackup.bat UNEXPOSE Y: end backup
