WD MyCloud Recycle Bin Behavoir

Does anyone have experience with the Recycle Bin for the WDMyCloud EX2.

I deleted some files maybe 5 months ago then powered off the device and put it into storage. We had Mirrored Storage Space Encrypted with BitLocker that had a copy of the files not accepted the recovery key after a virus was discovered on our system. I was wondering if it was possible to bootup the WDMyCloud and recover what we can from the device.

My fear is that the Recycle Bin is timed and if I power up the MyCloud it could potentially purge the files. I rather not manually mount the device if possible.
