Raidrive/Netdrive are 2 programs that have a similar behavior to SCD, to my knowledge. I don't know if in their deeper process they have differences. I suppose that those of us who have accounts with gdrive that are unlimited precisely hire themselves thinking of using them, among other things, as data storage of different sorts and SCD is a program that claims total support for working in the cloud in a secure manner regardless of whether you plan to store 1Mb or I don't know how many Tb, well that would have to be if they couldn't declare it as such. That said, I appreciate your expert explanations.
