That’s a total of 390 GB.
For the record, as recent experiments showed, 360 GB is an absolute minimum to build 0.18 Q.
I don’t think so.
I’ll say, between 3 and 6 € (VAT included).
Also, if using Docker please be aware that some cheap cloud VM won’t support it.
It seems a bit long for such a server (and time is money 
).
What was the method used ?
Did you keep the logs ?
