RAIDiator 4.2.30 where to rollback snapshots?

We have a ReadyNAS 3200 still running RAIDiator 4.2.30. There are snapshots on there that are taken every 8 hours. I need to roll back to one of them, but I don't see the option anywhere. I see where to set them up on the web interface. I see them visible as shares when browsing the device on the network, but I don't see any option to go back to one of them.

Can someone point me in the right direction?

Thanks!

Snapshots on RAIDiator 4 and snapshots on ReadyNAS OS 6 are two completely different features.
Snapshots on ReadyNAS OS 6 are BTRFS snapshots, which allow block level versioning and are implemented on subvolumes. They allow to setting a subvolume read-only so that all write operations are committed to another subvolume. You retain both subvolumes (or more) until consolidation is requested by the user or the system.
Snapshots on RAIDiator 4 are just a buffer area and a time window. During the time window, all the write operations on the data won't be committed to the volume but to that buffer area instead. When the time window ends, all the data from the buffer area is consolidated with the main volume. This is useful for taking consistent backups of the data volume but can't be used for versioning.

More information:

If I use credentials that have no rights to the ReadyNAS, and try to open one of the -SNAP shares through Windows Explorer, it bounces with invalid credentials. But if I use credentials that do have permissions, I get Error code: 0x80070043 The network name cannot be found.

  You can refer to the User Manual of RAIDiator 4 on page 98: http://www.downloads.netgear.com/files/GDC/RNDU2000/ReadyNAS_Business_SW_05Nov13.pdf
  And ReadyNAS OS 6 one page 105: http://www.downloads.netgear.com/files/GDC/READYNAS-100/READYNAS_OS_6_SM_EN.pdf

    Well, crap.
    
    We got hit with a cryptolocker attack, and was hoping to bring the data back through snapshots. I had inherited this system here, and assumed (you know what that's worth) functionality that apparently isn't there.
    
    I still can't access the snaps which I find odd.
    
    Thanks anyway!
