 ====== Windows System (Bare Metal) Backup Set ======
-AhsayOBM allows you to back up the whole Windows System with the Windows System Backup Set.
+AhsayOBM allows you to back up the whole Windows System with the Windows System Backup Module. This module of AhsayOBM provides you with a set of tools to protect your mission critical systems / personal computers on Windows operating system platforms. This includes an image-based / bare-metal backup feature, that leverages Microsoft’s native Wbadmin command-line tool ([[http://go.microsoft.com/fwlink/?LinkId=140216]]), and recovery feature, to ensure that your servers and computers are protected even if they are lost or destroyed entirely.  The image can be recovered onto a new device if necessary.

+==== Other Requirement and Limitation ====
+<WRAP indent>
+=== AhsayOBM Installation ===
+Make sure that AhsayOBM is installed on the computer to be backed up.
+=== Add-on Module Requirement ===
+Make sure that the Windows System Backup add-on module is enabled for your AhsayOBM user account.
+{{public:ahsay_wiki_module_windows_system_1.png?640}}
+=== Backup Quota Requirement ===
+Make sure that your AhsayOBM user account has sufficient quota assigned to accommodate the storage for the system backup. Please Contact your backup service provider for details.
+=== AhsayOBM Licenses ===
+AhsayOBM licenses are calculated on a per device basis:
+  * To backup users with 1 backup client computer (e.g. 1 AhsayOBM installed), 1 AhsayOBM license is required.
+  * To backup users with multiple backup client computers, the number of AhsayOBM licenses required is equal to the number of devices. For example, if there are 10 users to be backup with 3 backup client computers, then 3 AhsayOBM licenses are required. Please contact your backup service provider for more details.
+=== Windows Server Backup (WSB) Features ===
+For Windows server platforms, the Windows Server Backup feature must be installed in order for either the system backup to take place. Confirm in the Server Manager, the feature can be added by selecting Add Roles and Features.
+{{public:ahsay_wiki_module_windows_system_2.png?640}}
+=== Latest Service Packs from Microsoft ===
+Ensure that you have the latest service packs installed.
+Updates to the Windows operating system improve its performance and resolve known issues with Windows Server Backup.
+=== Temporary Storage Location ===
+Make sure that the storage location configured for the system image is set to a supported location.
+{{public:ahsay_wiki_module_windows_system_3.png}}
+The temporary storage location is required by the WBADMIN utility to temporary store the image file during the backup set.
+The machine requires an additional drive to accommodate the spooling of the System State image file. As you can on our sample screen shot above, we have three (3) drives in total, Local Disk C:, Temp1 E:, and Temp2 F:
+If by any chance the machine has only one (1) drive and it is his/her Local Disk C:, then one of the following options will need to be implemented
+i. An extra physical drive will need to be installed
+ii. The existing C: drive will need to be repartitioned to create an additional drive, i.e. D:
+iii. A USB drive needs to be connected
+iv. Setup a network drive
+Refer to here for more details about the restrictions:
+[[public:5165_restrictions_on_the_temp_for_the_windows_system_state_and_system_backup|Restrictions on the temporary storage location for the Windows System State and System backup image file]]
+=== Disk Space Available in Temporary Storage Location ===
+Make sure that there is sufficient disk space available in the storage location for the backup set. For a system backup, it will typically require disk space of the total used size of all volumes selected for backup.

+=== Maximum Supported Disk Size ===
+For Windows Vista, or 2008 / 2008 R2 Server, source volumes with size greater than 2 TB (e.g. 2040 GB - 2 MB = 2088958 MB) are not supported.
+This limitation is related to the .vhd file size limit.
