Specifying the VSS restore method
Select the required VSS restore method and click Next:
VSS Restore performs an online restore of the selected backup session to the original backup source (or alternate location) using the destination computer’s Microsoft VSS tools.
File Restore allows you to selectively restore individual files from a backup session. This is a pure file restore, which is useful with the corresponding Microsoft SQL Server, Microsoft Exchange Server, or Microsoft SharePoint Server management tools.
File Level Restore is available for Microsoft Hyper-V Server and Microsoft Hyper-V Server Cluster backup sets that were backed up with the Use FLR option. This allows restores of individual files that were on the virtual machine’s virtual disk(s).
Granular Restore applies to Microsoft Exchange Server 2010 or later and Microsoft SharePoint Server 2010 or later.
NOTE:  For more information, see “Backup / Restore of Microsoft Exchange Server (VSS-aware backup sets)” and “Backup / Restore of Microsoft SharePoint Server 2010 or later (VSS-aware backup sets)”.
