====== Granular Restore for VMware / Hyper-V

==== Requirements ====  

<WRAP indent>
=== Supported Backup Modules ===
Granular restore is supported on VMware backup sets created and backed up using AhsayOBM v8.1.0.0 or above installed on a Windows platform with the Granular Restore feature enabled on the backup set.

=== License Requirements ===
An OpenDirect / Granular restore add-on module license is required per backup set for this feature to work. Contact your backup service provider for more details.

=== Backup Quota Storage ===
As compression is not enabled for Granular backup sets, to optimize restore performance, the storage quota required will be higher than non-Granular backup sets. Contact your backup service provider for details.

=== Operating System ===
AhsayOBM must be installed on a 64 bit Windows machine as libraries for Granular only supports 64 bit Windows operating system for VMware ESXi/VCenter. AhsayOBM must be installed on the following Windows Operating Systems:
| Windows 2008 R2 SP1 or above | Windows 2012 | Windows 2012 R2 |
| Windows 2016 | Windows 7 SP1 or above	| Windows 8 |
| Windows 8.1 | Windows 10 | |

=== Temporary Directory Requirement ===
Temporary Directory Folder should have at least the same available size as the guest VM to be restored and should be located on a local drive to ensure optimal performance.

=== Available Spare Drive Letter ===
One spare drive letter must be available on the Windows machine for the granular restore process, as the VDDK virtual disk is mounted on Windows as a logical drive. AhsayOBM will automatically take the next available drive letter in alphabetical order for the mounted virtual disk.

NOTE
The Windows drive letters A, B, and C are not used by granular restore.
The granular restore assigned drive letter(s) will be released once you exit from AhsayOBM UI.

</WRAP>

=== Network Requirements ===
Recommended minimum network speed is at least 100Mbps download speed. 

The network bandwidth requirements will increase in proportion to the size of the guest VM and the incremental delta chain length to ensure optimal performance. Working with limited network bandwidth may severely affect the granular restore performance. 
You can use an online network speed test website (e.g. [[http://www.speedtest.net]]) to get an idea of the actual bandwidth of the machine. 

=== Permissions ===
  * The Windows login account used for installation and operation of the AhsayOBM client machine requires Administrator privileges. 
  * For Granular Restore, Windows User Account Control (UAC) must be disabled.

=== Other Dependencies ===
The following dependencies are restore related and therefore they will be checked by AhsayOBM only when granular restore is performed. Absence of these elements will not affect the backup job but would cause the restore to fail.
