amazon web services - Create copy of EC2 instance and launch as new instances -


i setup 1 mail server in 1 ec2 instances. want copy whole instance , launch new instance.

i'm confused snapshot , ami, please suggest how it.

when talking creating copy or clone of instance, there's 2 aspects consider:

  • the configuration of instance itself, such instance type, security group, iam role , network subnet
  • the contents of disk volume(s)

to launch instance same instance configuration, use launch more this option in actions menu, can launch new instance same configuration. select original ami used launch initial instance -- please note means have same disk sued when launching initial instance, not have copy of data stored/changed on initial instance since first started.

if wish make perfect copy of instance, including contents of disk volume(s), create ami (see documentation linux , windows). make copy of disk volume(s) instance launched ami have same data on disk. then, launch new instance ami.
