Systems, Methods, and Computer Program Products for Instant Recovery of Image Level Backups
First Claim
1. A system for recovering one or more virtual machines from an image level backup, comprising:
- a hypervisor configured to receive a selection of at least one virtual machine disk image file and at least one virtual machine configuration file corresponding to a virtual machine (VM) to be recovered, wherein the at least one virtual machine disk image file and the at least one virtual machine configuration file are included in an image level backup file;
a virtual storage communicatively coupled to the hypervisor and configured to receive contents of the image level backup file from a data conversion engine;
the data conversion engine configured to;
receive a request for a data object from the hypervisor;
determine at least one data portion of the image level backup file, wherein the data portion includes the requested data object;
perform at least one of partial decompression, de-deduplication, and decryption of the image level backup file to extract contents of the data portion on-the-fly at the time the data object is requested by the hypervisor without fully extracting the image level backup; and
represent the extracted contents in the virtual storage;
the VM, wherein the hypervisor is configured to launch the VM, and wherein the hypervisor is configured to provide to the VM access to contents of the at least one virtual machine disk image file and the at least one virtual machine configuration file through the virtual storage; and
a changes storage configured to store virtual disk data changes inflicted by recovery of the data object from the image level backup file, wherein the changes storage is implemented using virtual storage logic.

Abstract
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.

11. A method for recovering one or more virtual machines from an image level backup, comprising:
-
receiving one or more restore parameters; initializing a virtual storage; receiving a selection of at least one virtual machine disk image file and at least one virtual machine configuration file corresponding to a virtual machine (VM) to be recovered, wherein the at least one virtual machine disk image file and virtual machine configuration file are included in an image level backup file to restore from; performing at least one of partially decompressing, de-duplicating, or decrypting the image level backup file on-the-fly to extract a data portion so as to provide contents of the data portion to a hypervisor without fully extracting the image level backup file, wherein the extracted data portion is represented in the virtual storage; attaching the virtual storage to the hypervisor; attaching a changes storage to the virtual storage or to the hypervisor, wherein the changes storage is configured to store disk data changes inflicted by recovery of the VM; and launching, by the hypervisor, the VM using the virtual storage. - View Dependent Claims (12, 13, 14, 15, 16, 17, 21)

18. A non-transitory computer-readable medium having instructions stored thereon that, when executed by one or more processors, cause the processors to perform operations to recover for recovering one or more virtual machines from an image level backup, the operations comprising:
-
receiving one or more restore parameters; initializing a virtual storage; accessing an image level backup to restore from; receiving a selection of at least one virtual machine disk image file and at least one virtual machine configuration file corresponding to a virtual machine (VM) to be recovered, wherein the at least one virtual machine disk image file and virtual machine configuration file are included in the image level backup file; performing at least one of partially decompressing, de-duplicating, or decrypting the image level backup file on-the-fly to extract a data portion so as to provide contents of the data portion to a hypervisor without fully extracting the image level backup file, wherein the extracted data portion is represented in the virtual storage; attaching the virtual storage to the hypervisor; providing contents of the extracted data portion to the hypervisor; launching, from the hypervisor, the VM using the virtual storage; and determining if the operating system (OS) of the VM has booted successfully. - View Dependent Claims (19, 20)
