Virtual machine backup from storage snapshot
Abstract:
Disclosed herein are system, method, and computer program product embodiments for virtual machine (VM) backup from a storage snapshot. An embodiment operates by receiving selective backup parameters including a VM to backup and then creating a VM snapshot associated with the VM. Next, an offset table associated with a virtual disk of the VM stored on a storage is retrieved. The embodiment further includes generating a storage snapshot and deleting the VM snapshot and then promoting the storage snapshot to a new logical unit number. The promoted storage snapshot is then mounted to the backups server. The virtual disk data is backed up to a backup storage using the offset table from the storage snapshot. The storage snapshot is dismounted from the backup server and deleted from the storage.
