According to one embodiment, a method identifies a plurality of parameters associated with one or more virtual machines to be backed up to a backup storage system and a number of available backup proxy sessions. The method further assigns each of the available backup proxy sessions to a virtual disk of the one or more virtual machines based on the plurality of parameters and the number of available backup proxy sessions. The method then initiates backup operations, wherein each assigned backup proxy session is to back up a corresponding virtual disk to which it is assigned.

Prioritizing virtual machines for backup protection at a virtual machine disk level

Embodiments are described for enabling file level recovery (FLR) process for dynamic and VHD disks in a data storage system. For VHD disks, certain intelligence is provided to a FLR agent installed in a helper VM to discover the VHD disks in the source VM. The FLR agent detects the presence of the VHD disk in the source VM, and upon detection, performs an Instant Recover (IR) operation of the source VM. It mounts the VHD disk and contained VHD files in the source VM on the helper VM to expose the VHD files to the FLR operation, and a backup operation copies the exposed VHD files to a destination folder on a destination VM. The memory mapping to the VHD disk is maintained by the helper VM during the FLR operation.

System and method to enable file level recovery of virtual disks and dynamic disks

A method for performing a backup operation includes receiving, by a backup storage device, a backup request, and in response to the backup request: identifying a plurality of virtual machines (VMs) associated with the backup request, identifying a VM of the plurality of VMs that is in an orphaned state; and, initiating a backup for each of the plurality of VMs except the VM.

Method to detect and exclude orphaned virtual machines from backup

Embodiments are described for enabling file level recovery (FLR) process for dynamic disks in a data storage system. A source virtual machine (VM) stores data files after a data backup operation and to be restored to a destination VM using the FLR operations; a copy of the source VM is spawned and has an Instant Recover (IR) execution component performing IR operations. A helper VM is spawned using the IR operation of the source VM copy. A FLR agent installed on each of the source VM copy and the destination VM is configured to identify a disk on the source VM as being a dynamic disk, and to allow the helper VM to act as a file transfer facilitator between the source VM and the destination VM. In this way, dynamic disks on the source VM are distinguished from regular disks even when they has the same UUID.
