System Recovery—Breaking through the Dissimilar Hardware Restore Challenge
Restore Anyware for Hardware Migration and Hardware Repurposing Migration is part of the lifecycle for Windows servers and desktops. When hardware becomes outdated and is replaced, the system must be migrated-using a process that is equivalent in many ways to a bare-metal recovery. It is even likely that a user's current migration strategy closely resembles that for bare-metal system recovery. The two processes share many of the same shortfalls. Using Symantec Backup Exec System Recovery in combination with the Restore Anyware capability offers an ideal solution to hardware migration woes; moreover, if it is already being used for bare-metal system recovery, this combination is a natural centerpiece for any hardware migration strategy.
Hardware migration strategies Any migration procedure should define along with the reasons for the migration-the steps involved, the fallback precautions, and any other important factors that can influence the migration process.
Two conflicting philosophies influence technology upgrades. The first is, "If it isn't broke, don't fix it." Obviously, if an organization has a functional, easy-to-use, well-designed server infrastructure, the idea of upgrading may not be so appealing. The second philosophy is, "Those who fail to upgrade their technologies perish." But that means restoring each server to new hardware with new drivers that have their own peculiarities, and then cascading hardware upgrades "down the line" until all servers on the list are upgraded to the next highest level, with the bottom server being "dropped out of the pool."
No matter which approach is taken, Restore Anyware is an invaluable aid to a hardware migration plan. Hardware failures and upgrades are both inevitable - but with the Restore Anyware capability of Backup Exec System Recovery, users are well prepared to deal with either.
Preparing a New System for Migration Any migration procedure involves planning and pilot-testing the migration, executing it, and allowing a short interval for rollbacks, if necessary. Following are a few key steps in the process, demonstrating how Symantec Backup Exec System Recovery with Restore Anyware can help (see figure 3):
Ensure that the SRD recognizes the storage controller(s) and NIC(s) in the new server and that there is a backup of the native state of the new server. Install the Symantec Backup Exec System Recovery software onto the new server. During this process, the new computer's hardware can be checked for any drivers that the SRD CD may lack.
If new drivers are needed, it's easy using a wizard-driven interface to create a customized recovery CD tailored to the specific environment.
With an updated, customized SRD, create a base recovery point for the new server and then store it in the recovery point warehouse, along with the suggested configuration information worksheet for the server.
