Class: CopyAmi
Overview
Copy a given snapshot to another region
-
start up instance in source-region, create a snapshot from the mounted EBS
-
then create volume from snapshot, attach volume, and mount it
-
start up instance in destination-region, create empty volume of same size, attache volume, and mount it
-
copy the destination key to the source instance
-
perform an rsynch sync -PHAXaz –rsh “ssh -i /home/$src_user/.ssh/id_$dst_keypair” –rsync-path “sudo rsync” $src_dir/ $dst_user@$dst_public_fqdn:$dst_dir/
-
create a snapshot of the volume
-
register the snapshot as AMI
-
clean-up everything
