Configuring the proxy host for backup
This section describes the general procedures for configuring the proxy host for backup in both ESXi and Windows environments. Configure the ESXi proxy host to connect to the storage array using iSCSI or Fibre Channel. In deployments where vCenter is used to manage ESXi hosts in general, note the following with respect to the ESXi proxy host. The ESXi proxy host should not normally be managed by vCenter. If there is a requirement to manage the ESXi proxy host with vCenter, then a different vCenter must be used than that which is managing ESXi within the Edge appliances. If the ESXi proxy host is managed by vCenter, then it should not be in lockdown mode. The Core should always be configured to communicate with the ESXi proxy host directly.
1. Configure the Windows proxy host to connect to the storage array using iSCSI or Fibre Channel.
2. Configure a local administrator user that has administrator privileges on the Windows proxy host.
3. Create a user with administrator privileges.
4. Create the following registry setting:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
For Key Type, specify DWORD.
For Key Name, specify LocalAccountTokenFilterPolicy.
Set Key Value to 1.
5. Disable the Automount feature through the DiskPart command interpreter automount disable command.
6. Add the storage array target to the favorites list on the proxy host to ensure that the iSCSI connection is reestablished when the proxy host is rebooted.
