Unable to delete snapshots
I have 1.24Tb of data on my NAS102 but I have been getting messages that I cannot do a Windows Backup due to insufficient space. Looking into it I find there is over 1.98Tb of Snapshots and only 298....

if you hover over a share, you will see a settings wheel on the right. Click on that, and select "recover". That will give you a pop-up which (after a while) should show you all the snapshots for the share. These all have date names.
You can select more than one by holding down the shift key. Then right-click and you will have a "delete" option. Delete the oldest first.
It might take a while for the space to be reclaimed. After the snapshots have all been deleted you should run a balance, and when that is done you should also run a defrag.
If the snapshots don't show up in "recover" or if the space is not reclaimed you might need to contact support.
BTW if you click on the settings wheel for the share, and choose "settings" there is a snapshot tab that gives you controls over snapshot use. Custom snapshots lets you select a retention period (after which the snapshots are deleted).

Thank you for the succinct and clear advice, that just cleared out a huge amount of space. All I need now is to ask you to explain where the defrag command is. I also assume that Balancing means I defrag one HDD and then get the second HDD to mirror the changes?

Go to System > Volumes, click for the settings wheel for the volume and you should see the volume maintenance options. You can even set them up to run on a schedule.
Volume maintenance is done on an entire volume.
Balancing is a different thing to running a defrag.
Balancing moves the data and metadata around to empty chunks so they can be returned to unallocated space. It doesn't defrag the files when it does.
