Using Diskshadow at the command prompt you can wipe away all the old backups.
Open Server Manager > File and Storage Services > Volumes
For instance this is my backup location. \\?\Volume{9f7925e7-0a88-47a6-a6da-357dd7229cb1}.
Now launch an Elevated Command Prompt and type "Diskshadow" without the quotes.
Then type "List Shadows all" and you should see the volume identifier many times over.
In my case I had 60 shadow copies listed with that volume.
Run this command using your volume information in my case for example:
Delete Shadows Volume \\?\Volume{9f7925e7-0a88-47a6-a6da-357dd7229cb1}
This removed all but the latest backup. I tested by restoring both a new and old file to my server and running a manual backup all worked perfectly. Be aware the first backup will take some time to complete while it rebuilds the backup set however it wont consume anymore space than a normal scheduled backup.
I'm sure someone much smarter than me could write an app that would be able to go through the shadows and show the backups by date/time and give you the option of deleting certain backups.
I hope this helps out and as usual be careful with your data. Make backups and use this tutorial at your own risk.
