 Make sure that your AhsayOBM user account has sufficient quota assigned to accommodate the storage for the guest virtual machines.  Contact your backup service provider for details.

 ==== Run Direct Requirements ====
 Run Direct is a feature that helps reduce disruption and downtime of your production VMs. To utilize the Run Direct feature, ensure that the following requirements are met:
-=== VDDK Backup Mode Requirement ===
+<WRAP indent>
+=== VDDK Backup Mode ===
 Run Direct restore is only supported for virtual machine that is backed up in VDDK mode (Virtual Disk Development Kit) for ESX/ESXi and vCenter setup. With VDDK mode, the backup speed is enhanced because the generation of the delta file of the VM are performed directly by the ESX/ESXi or vCenter itself. For being able to backup in VDDK mode, AhsayOBM must be installed on a supported Windows operating system platform.

 == License Requirement ==
 The VMware vSphere Storage APIs, which are essential for VDDK backup mode, are included with the VMware vSphere Enterprise Standard, Enterprise and Enterprise Plus Edition. Ensure that the license requirement is met.

 This is due to the percent-encoding specified in the URL standard is not supported for ESXi based HTTP(S) file access. To resolve the issue, please rename the corresponding file to avoid special characters. For instructions on renaming a virtual machine, please refer to the following knowledge base article from VMware: https://kb.vmware.com/s/article/2031763
+</WRAP>
+=== Backup Destination ===
+When a Run Direct restore is performed, the backup destination containing the guest VM files is mounted on the VMware host as NFS datastore.
+Ensure that the following requirements are met by the backup destination of the VMware VM backup set:
+  * Destination must be accessible to the VMware host.
+  * Destination must have sufficient disk space available for the Run Direct restore. There should be 1.5 x total provisioned size of all VMs selected for backup.
+  * For Run Direct restore of 1 VM with provisioned size of 100GB, there should be 150GB (e.g. 1.5 x 100GB) of free space available in the Destination.
+No Compression and Encryption - Data backed up to a Run Direct enabled destination is not compressed or encrypted to optimize restore performance as Run Direct will make the VM restored by running the data directly form the backup files in the backup destination.
+Operation System of the Backup Client Computer
+  * Run Direct restore is only supported by AhsayOBM installation on Windows.
+  * To utilize the Run Direct feature, make sure that AhsayOBM is installed on a supported Windows platform.
+Restore to Alternate Location
+  * When performing a Run Direct restore to Alternate Location, only one VM can be selected per restore session. \\ {{public:ahsay_wiki_module_vmware_requirement_03a.png}} \\ {{public:ahsay_wiki_module_vmware_requirement_04.png?640}}
+  * Consider to create separate VMware VM backup set for each VM that you intend to perform Run Direct restore (e.g. VMs that you may restore to alternate location).
+Dedicated NFS Service - A dedicated AhsayOBM NFS Windows service is introduced to allow Run Direct session to continue even if the AhsayOBM user interface is closed.
+By default, the AhsayOBM NFS service is started as Local System, which does not have sufficient permission to access any network resources (e.g. the AhsayOBM NFS service does not have sufficient permission to access the VM backup files on network drive).
+Make sure that the Log on setting of the Ahsay Online Backup Manager NFS Service is configured with an account with sufficient permission to access the network backup destination where the backed up VM data are stored.
+  - Under Control Panel, open Administrative Tools then Services.
+  - Right click on Ahsay Online Backup Manager NFS Service, select the Log on tab.
+  - Select the This Account option.
+  - Enter the login credentials of an account with sufficient permission.
+  - Restart the service afterward.
+</WRAP>
+==== Non-VDDK Backup Mode Requirements ====
+For VM that cannot be backed up in VDDK mode, non-VDDK backup mode will be used instead.
+  * Independent Disk (Persistent or Non-persistent)
+  * Independent disk can only be backed up if the VM is shutdown during a backup.  If the VM is started up during the backup, all independent disks selected for backup cannot be backed up.
