thanks that freed up a substantial amount of space, how do I stop these snapshots being created everytime I delete something, I run two backups so snapshots is not required.
Snapshots are also created when a ReadyNAS "push" backup starts. (That is, when the source of the backup is local). The backup job actually backs up the snapshot. This ensures the backup is coherent.
The snapshot is deleted when the backup completes, but there might be some scenarios when that doesn't happen. For instance, if there is a power loss during the backup, the snapshot might not be deleted.
Overall, my suggestion is look for new snapshots every few days for a bit, and see if you are dealing with a recurring issue or not.
Normally, you click on snapshots on the admin web ui's share page, and then click on each share in the popup window. That should show you the snapshots, and you can right-click on one (or more) and delete them.
Hi thanks for your response, I put the following in to terminal but it didnt work; what am I doing wrong. I deleted some more stuff from my drive via normal UI and it keeps creating snapshots and not giving me back the space, very confusing as I have diabled snapshots.

Your path is wrong - I believe it should start with /MASTER.
Also, each snapshot is a btrfs subvolume. So maybe try btrfs sub delete -c /MASTER/.snapshots/2/snapshot and see if that deletes that particular snapshot.
Are you using ReadyDR backup?
You might also search in the logs for when these snapshots are being created - that might give you a clue on where they are coming from.

I've just tried to delete the others, how do I delte these two:
root@JBSTUDIO:~# btrfs subvolume list -R /data | grep snapshot
ID 272 gen 28173 top level 271 received_uuid - path MASTER/.snapshots
ID 2876 gen 27761 top level 272 received_uuid - path MASTER/.snapshots/231/snapshot
