Abstract
A virtual machine can be migrated from a first physical server to a second physical server. Rebaselining of the virtual machine after migration can be mitigated, thereby mitigating recopying of the virtual machine's data to a second location on a backup data store, for example. A unique identifier for the virtual machine is used to determine if it has been migrated to another physical server. If a migration is detected, it is determined whether the virtual machine had a data store backup relationship prior to the migration. If a prior data backup relationship is detected, this prior relationship is used for the virtual machine at its migrated location on the second physical server for subsequent data backups. Conformance testing is used to mitigate multiple data backups of the VM, comprising data backups to a data store for both the first and second VM hosting servers.
