How to import file backups (.NBD) into the restore tab
This guide will provide a step-by-step instructions on how to import file backups (.NBD file) into the restore tab. You will need to do this if you have backups that you are bringing from another computer that had NovaBACKUP and you want to restore file from those backups.
Once your backup set is Imported you can then restore individual files and folders from the backup set (.NBD) via the Restore tab.

Here is a screenshot of how to select files to restore:
If something is damaged in the current restore "media index records", in place on your local hard drive, you may have to perform a clean of the media index records and then re-import the backup set again to be able to restore files from it.

If for other reasons your backup set (.NBD file) cannot be Imported, you can also attempt the Direct Restore method to restore all of the files and folders from the backup set (.NBD) to extract the contents of your backup set to a folder of your choice, this is an all or nothing restore and does not allow you to select individual files and folders to restore.
If the backup set is damaged it will stop extracting the files from the backup set at the point where the backup set (.NBD) is damaged.
