Hi Roger310,
What is the storage capacity of your Google drive? Google Drive capacity starts with a 15GB free storage. They have a subscription plan for additional storage capacity. You may check this link for more information regarding that.
Regards,
- Roger310Dec 27, 2018AspirantThat's not the issue at this point. But yes I do only have the 15G with google at this point.
I have 64G of information on the Nas drive.
Why is the snapshot also 64G? It seems to me that it should be much smaller as its supposed to be an image file correct?- StephenBDec 28, 2018Guru - Experienced User

Each snapshot has the full contents of the shares when they were taken, so if you have 10 snapshots, backing them up to other storage would take 10x the room it takes to back up the share.
The trick is that data blocks that haven't changed from the original share are held in common, so only the changes take space on the disk.
This post might help clarify how they work: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/ReadyNAS-312-Need-Help-Understanding-Snapshots/m-p/936586#M171850
- Roger310Dec 28, 2018AspirantThank you! That explains what I'm seeing.
So my next question than is there a means of creating an image file to restore from?
I'm not sure that it needed as the NAS is running g in raid 1. But I never trust a single device.
