Thanks for the advice Dan.
The reason I like to use S3 is that I like to run jobs, log out and
have them automatically
shut down when done. At the moment I'm just running the following
automated shutdown of my instances from within my R script:
shutdown <- function(time=0) return(system(paste("echo 'sudo halt' |
at now + ",time," min",sep="")))
Even if I set my instance's shutdown behaviour to "terminate" (in the
AWS management console),
those EBS volumes seem to persist when I automate termination this
Do you perhaps have a recommendation on how better to make sure my
down once the job is done? Ideally it would be great if it could fire
off a quick
email too, but this doesn't seem so easy to do unless I create my own
AMI I think.
Thanks a ton,
