Zusammenfassung:Backup of application data associated with an application executing in a virtual machine managed by a hypervisor is performed. Backup of the application data includes retrieving a Logical Unit Number (LUN) identification (ID) used by the application to store the application data in a storage volume. Backup of the application data also includes performing a virtual storage resolution for the LUN ID to determine whether the application data is stored in the storage volume identified by the LUN ID based on a first virtual mapping or a physical mapping. Backup also includes storing in metadata for the backup the LUN ID and whether the LUN ID is based on the first virtual mapping or the physical mapping. Backup includes creating a backup of the application data stored in the storage volume. Application data can subsequently be restored based on the application data that is backed up.
