A Hyper-V VM that is being protected by Rapid Snap for Virtual (agentless protection) is indicated in the left navigation area by the host icon . The settings for a Hyper-V agentless VM the same as a typical protected machine with the exception of the Hyper-V section at the bottom of the Settings page. The following task provides instructions for only the Hyper-V section settings. For all other protected machine settings, see Viewing and modifying protected machine settings.

The settings for a VMware VM that is protected agentlessly include the same settings that are used for a typical protected machine, with one exception. The vSphere section of the Settings page includes settings that apply only to agentlessly protected VMware VMs. The following task provides instructions for only the vSphere section of the Settings page. For all other protected machine settings, see Viewing and modifying protected machine settings.

In Rapid Recovery, you can modify the settings to manage the data transfer processes for a protected machine. The transfer settings described in this section are set at the protected machine level. To affect transfer at the Core level, see Modifying transfer queue settings.
Rapid Recovery supports Windows 8 and Windows Server 2012 for normal transfers, both base and incremental, as well as with restore, bare metal restore, and virtual machine export.
There are three types of transfers in Rapid Recovery:
• |
Snapshot. Backs up the data on your protected machine. Two types of snapshots are possible: a base image of all protected data, and an incremental snapshot for data updated since the last snapshot. This type of transfer creates recovery points, which are stored on the repository associated with the Core. For more information, see Managing snapshots and recovery points. |
• |
Virtual Machine Export. Creates a virtual machine (VM) from a recovery point, containing all of the data from the backup of the protected machine, as well the operating system and drivers and associated data to ensure the VM is bootable. For more information, see VM export. |
• |
Restore. Restores backup information to a protected machine. For more information, see About restoring volumes from a recovery point. |
Data transfer in Rapid Recovery involves the transmission of a volume of data along a network from protected machines to the Core. In the case of replication, transfer also occurs from the originating or source Core to the target Core.
You can adjust the performance options to best support your business needs and fine-tune the performance based on your environment. For more information, see Throttling transfer speed.
When you throttle the transfer speed, you limit the amount of your network bandwidth dedicated to file transfers from Rapid Recovery. When setting up replication, for example, throttling can reduce the likelihood that the transfer of prior recovery points to the replicated Core consumes all of your network bandwidth.
CAUTION: Throttling transfer speed is not always required or recommended. This information is provided to provided insight into a potential solution for performance issues in your Rapid Recovery environment. For example, sometimes, throttling may solve issues related to repeated transfer failures or network slowdowns caused by transferring a substantial amount of data for your protected or replicated Cores. |
Ultimately, the process of network throttling involves trial and error. Quest recommends that you adjust and test your transfer settings, and revisit these settings periodically to ensure that your settings continue to meet your needs.
Adjusting transfer speed should be accomplished on an individual machine basis. In the Core Console, navigate to a specific machine, select Settings, and adjust the Transfer speed. For specific information about viewing and changing these settings, see Viewing and modifying protected machine settings. That topic also includes descriptions of each of the settings used for throttling transfer. Those descriptions may be useful in determining which settings you should experiment with first.
The four main settings involved in throttling transfer speed are described in the following table:
Quest recommends adjusting and testing the other settings prior to changing the default setting for outstanding reads per stream, unless directed otherwise by a Quest Support representative. When tuning and testing this setting, start with a value of 24.
