Recently we performed our annual Disaster Recovery test.  We have learned something very valuable every year and tried to adjust our recovery plans accordingly, with this year being no different.  Even with all the new technology, DR still seems to be a tricky undertaking.

The first year we tested our plan we found that we really, really, REALLY, don’t want to restore Active Directory onto unlike hardware.  The following year we had gotten a node onto our MPLS cloud which allowed us to have a replicated AD server at the DR site.  This greatly reduced the problem of restoring AD.  The year after that we tested our phone system portion of the DR plan and discovered that working with the telco in a DR situation will be challenging at the very least.  In the two years since that second test there have been some major changes that removed our ability to have replicated AD, so we were back to square one on that front.

This year we thought we would do a restore of our two year old VMWare environment.  We had decided to keep the scope to restoring only “Tier 0” service.  This included VMWare ESX , Symantec BackupExec, vSphere, and AD.  Time permitting we planned to restore as many servers as possible beyond the Tier 0 that were the bare minimum.

In the last year we had made the choice to purchase Symantec’s BackupExec Agent for VMware Virtual Infrastructure (AVVI).  This is a BackupExec agent that allows you to backup VMWare Guest OS files directly through the ESX server and/or SAN.  The idea is that we would have our virtualized servers backed up to tape at the VMWare file level and that this would allow us to restore directly back to ESX.
