ec2 spot instance supported?

Virtualmin
1

Hi

  1. As the title suggests is virtualmin supported on ec2 spot instances, would there be any issues regarding restoring a server which has virtualmin installed from snapshot data? cPanel has an documented issue with this which is why I ask (https://documentation.cpanel.net/display/CKB/Launch+an+AWS+AMI+Instance) and i I could not find any answer on these forums or the interwebs if virtualmin has a similar issue

  2. Can I use the GPL licence to host upto 30 domains or do I need a licence?

  3. Can I transfer a full cPanel backup, ie files, database, emails ?

thanks
