Thanks for the reply. We have only used MSP360's CloudBerry since it works so well and didn't think about this scenario until recently. I think your option for encrypting with another product and then sending it is a viable option that we will have to weigh in if we wanted to circumvent this risk. Or we can wait and see if there is any inclination that the product will no longer be supported, we would then restore and then re-encrypt. We will most likely go with the latter so thanks for your response.

Is there an update to this response? We are thinking of the same consequence if something were to happen to CloudBerry in 30 years from now. Maybe the product line is dropped and we can't get the client installed somewhere. What happens to all of our long term backups that were encrypted?
