Systems, methods, and computer program products for instant recovery of image level backups

摘要

Systems, methods, and computer program products are provided for instant recovery of a virtual machine (VM) from a compressed image level backup without fully extracting the image level backup file's contents to production storage. The method receives restore parameters and initializes a virtual storage. The method attaches the virtual storage to a hypervisor configured to launch a recovered VM. The method stores virtual disk data changes inflicted by a running operating system (OS), applications, and users in a changes storage. The method provides the ability to migrate the actual VM disk state (taking into account changed disk data blocks accumulated in changes storage) so as to prevent data loss resulting from the VM running during the recovery and accessing virtual storage, to production storage without downtime. In embodiments, the method displays receives restore parameters in an interactive interface and delivers the recovery results via an automated message, such as an email message.

主权项

1. A system for recovering a virtual machine, comprising:
a restore operator console configured to receive a selection of an image level backup of the virtual machine and a data object of the image level backup; a data conversion engine configured to determine a data portion of the image level backup containing the data object and to perform content translation on the image level backup to extract contents of the data portion; a storage configured to receive the extracted contents of the data portion from the data conversion engine and to represent the extracted contents to a server; and one or more processors configured to execute at least one of: the restore operator console, the data conversion engine, and the storage.
