About using the command line to browse or restore Exchange granular backup images
You can use the command line to browse or restore granular backup images:
When you perform a snapshot restore of mailboxes or mailbox folders, specify the file names as relative to the Microsoft Information Store or DAG and to the database. For example:
Microsoft Exchange Database Availability Groups:\server1\Microsoft Information Store\ My-database\Database\John Q. Employee [JQEmployee]\Top of Information Store\Inbox\ Microsoft Information Store:\My-database\Database\John Q. Employee [JQEmployee]\ Top of Information Store\Inbox\
Use the "-granular_proxy" option with the bpduplicate command or the bplist command to specify a proxy host for a duplication operation
See Configuring the Exchange granular proxy host.
The following example shows how you can specify a proxy host with the bplist command:
bplist -t 16 -k exchgranpolicy -R -s 06/09/2016 16:00:00 -granular_proxy ProxyServerA "\Microsoft Information Store\My-database\ DeptA\EmployeeA\Top of Information Store\Inbox\*"
