Using Portal, you can share a VMDK from a vSphere backup. This process provides a UNC path (CIFS share) for accessing the VMDK on the machine where you want to restore files or folders.
After sharing a VMDK, you can access the disk using the UNC path provided. On supported Windows operating systems, the preferred method of accessing shared disks is to use the Dynamic Disk Tool (provided with the vSphere Agent). See Access a shared VMDK and restore files.
To share a VMDK from a vSphere backup:
1. On the navigation bar, click Computers.
A grid lists available computers.
2. Find the vSphere environment with files and folders that you want to restore, and expand its view by clicking the row.
3. Click the Jobs tab.
4. Find the backup job with files and folders that you want to restore, and click Restore in the Select Action menu for the job.
5. In the Choose What You Want to Restore dialog box, select Files and Folders.
6. Click Continue.
The Restore dialog box shows the most recent safeset for the job.
7. To restore data from another source, click a source in the Source Device list.
8. To restore from
an older safeset, click the Browse Safesets button. 
In the calendar that appears, click the
date of the safeset from which you want to restore. To the right of the
calendar, click the specific safeset from which you want to restore.
9. In the Items to Restore box, select the check box for the VMDK with files or folders that you want to restore.
10. In the Encryption Password box, enter the data encryption password. To view the password hint, click the Hint button.
11. In the Idle Time box, enter the number of minutes of inactivity after which the shared drive will automatically unshare. The Idle time can range from 2 to 180 minutes.
Note: The drive will not unshare as long as new data is being copied. If you copy the same data from a shared drive more than once, the system could time out because no new data is being read.
12. To use all available bandwidth for the restore, select Use all available bandwidth.
13. Click Share.
The Restore – Share Virtual Disk dialog box shows the process status. When the disk is shared, a UNC path appears in the Share box.
The drive remains shared while files are being copied, until there is no activity for the specified amount of idle time, or until you click the Unshare button.
14. Click Copy Path to Clipboard.
15. Use the path to access the UNC share, or send the path to another user who can access the shared VMDK, and copy the files and folders that you want to restore.
If the shared VMDK is a Windows dynamic disk, paste the path into the Dynamic Disk Tool on the machine where you want to restore files and folders.
16. To unshare the drive, click Unshare.
