Replacement drive help?

I think one of my original settings was i scheduled a backup task to create a backup of media each day - which i believe wrote the info to the backup share - thus creating a copy. and then the hidden mirrors you spoke about then created a copy of both of these shares? do you think this is accurate?

This explains what we are seeing - both why the files are showing up in backup, and why the volume is full.

If this is the case I believe I should delete the backup share completely from front view.

You can do that, or delete the folders in it, and leave the share empty. Disable the recycle bin in that share first though (if it is still on). That would resolve your space problem, giving you 420 GB more space.

But will this remove automatically the extra hidden backup which i don't see freeing up lots more space on my drive?

It wouldn't stop the mirroring, and you don't want it to.

If you still want more space, just add another 1 TB drive to the array. That will convert your mirror to a more sophisticated RAID format. You would have 2 TB of storage, and the RAID would still protect your data from a single drive failure. How that works is hard to explain, but it does.
