Abstract

Virtual machine backup is described. A backup copy is created of a data set associated with a virtual machine based on a backup schedule. A clone copy is created of the backup copy based on a clone schedule. The clone copy is stored on an external destination node including a disk and/or a tape. A disaster recovery copy may be created of the backup copy and metadata associated with the backup copy based on a checkpoint at an interval. A request to restore the data set may be received. The data set may be restored based on the backup copy, the clone copy, or the disaster recovery copy.
