"EBS snapshots cannot be moved between regions"

Not true. I've done this using Ylastic. See http://ylastic.com/features.html:

"Migrate EBS linux snapshots between regions."

"Migrate EBS windows snapshots between regions."

Takes a few minutes to kick off and does it all for you.

As you’ve used it - how long does it take? I read up, and I decided they where probably just making a new EBS volume in the new region, `netcat`ing the data across, and taking a snapshot of that new volume, with the `netcat`ed data.

So I did it by hand - that way. It it’d be pretty easy to tell if this was the case, because it really wouldn’t be fast….

It's not fast, they send you an email when it's done. It was a while ago now, but I recall it taking about 30 minutes before I got the email.

Interesting. I wonder if they use an undocumented AWS feature or are snapshotting the volumes and copying them. My guess is the latter.

The OA comment of "EBS snapshots cannot be moved between regions" should have "easily" inserted in there. I've seen quite a few full length processes for doing it, e.g:

http://serverfault.com/questions/336321/how-do-i-migrate-ama...

I'm 95% sure they are just putting a UI over that lengthy process. But as I say, I've tried it and it worked perfectly for me. This is their process:
