### Recovery Considerations

- Obtain the valid Microsoft license key for the Windows operating system to perform 1-Touch recovery operations.

- Ensure that Windows is not installed on the drive other than C:\. The unattended installation of Windows on a drive other than C:\ is not supported. You cannot perform the Online or Offline Restore when Windows is installed on a drive other than C:\.

- 1-Touch does not support recovery for multiboot systems.

- 1-Touch does not support recovery of disks managed by Veritas Volume Manager due to inconsistent results with VDS.

- 1-Touch recovery operations are not supported for system drive on GPT dynamic disk.

- 1-Touch recovery operations are not supported on a client with multiple instances.

- Restores are not supported for Resilient File Systems (Refs) and Storage Pools that operate on Microsoft Windows 2012 or Windows 8.0.

- You must use a wired internet connection to recover a laptop.

- You cannot restore mount points using 1-Touch recovery operations.

- During a 1-Touch recovery operation, a dynamic disk is converted to a basic disk and is recovered as a basic disk. You must manually bring the dynamic disk back online after the operation completes.

### Recovery Support

- 1-Touch recovery operations are not supported for USB disks. By default, system state backups do not back up the content in USB disks.

- 1-Touch recovery operations are supported for NVMe (non-volatile memory express) disks.

- 1-Touch support recovery of BitLocker Encryption enabled volumes with lock opened during backup; post restore this option is disabled and you need to manually enable the BitLocker Encryption option on the volumes.

- 1-Touch recovery operations are supported for systems which boot from SAN or the recovery of SAN attached disks.

- If the client computer has more than 100 disks attached, then the system drive is restored initially, and then the other drives and data are restored later.

- Use 1-Touch interactive recovery to restore a MediaAgent computer. You cannot use 1-Touch non-interactive restore operations to restore a MediaAgent computer.

### Partitions

- Ensure that the client does not have multiple active partitions. You cannot perform 1-Touch recovery operations if the client has multiple active partitions.

- If you have a recovery partition, make sure that it is removed prior to a backup operation.

### Network and Protocols

- Ensure that the TCP/IP Services are configured on the computer before performing the backup.

- IPv6 is not supported for 1-Touch recovery of clients.

- NIC teaming is retained only if the restore operation is performed to the same computer. After a 1-Touch recovery operation to a dissimilar computer, the NIC teaming configuration will not be maintained.

- 1-Touch recovery operations are not supported for VLAN (Virtual Local Area Network) configurations where the NIC (Network Interface Control) is configured with VLAN tagging.

Commvault software

### CommServe

To enable 1-Touch recovery, the Force per-client certificate authentication on CommServe option has to be turned off on the CommServe at least for the duration of the recovery. This option can be accessed from the CommServe Control Panel by clicking on Certificate Administration.

### Recovery Considerations

- Obtain the valid Microsoft license key for the Windows operating system to perform VirtualizeMe and 1-Touch recovery operations.

- Ensure that Windows is not installed on the drive other than C:\. The unattended installation of Windows on a drive other than C:\ is not supported. You cannot perform the Online or Offline Restore when Windows is installed on a drive other than C:\.

## Supported Hypervisors

1-Touch Recovery is supported for Microsoft Azure, Hyper-V, VMWare, and AWS hypervisors.

### VMware vCenter Server Support

The following versions are supported for vCenter Server and vCenter Server Appliance. vCenter Server support includes support for vSphere, Virtual Disk Development Kit (VDDK), ESX or ESXi, and file system versions as provided by the vCenter version.

For more information, see Correlating build numbers and versions of VMware products.

Generally, each version of the VDDK supports vCenter Server for the two previous major versions and for the next minor version. For example, VDDK 8.0.1 can be used with vCenter Server 7.x, or 8.0 Update 1.

When VMware issues new versions or updates, Commvault tests against the current service pack before announcing support. For new VMware versions or updates released between Commvault service packs, and for earlier supported versions or service packs, Commvault provides continuing support, including Hot Fixes as needed to address VMware changes to functions that affect backup and recovery.

#### vCenter Server Versions

- 8.x (all minor updates)

- 7.x (all minor updates)

### Support for Azure and AWS

You can VirtualizeMe to convert any physical computer to a Microsoft Azure Resource Manager virtual machine or an Amazon EC2 instance.

In addition to the Client system requirements, review the following Proxy Client Computer requirements for Azure and AWS hypervisors:
