Latency of cross region snapshot copy.

Looks like there is some sort of issue with cross-region encrypted snapshot copy. Support is working an open case on issue.

Turns out there was a problem in cross-region encrypted snapshot copy that caused infinite copy latency, i.e. the cross-region copy failed silently.

Redshift fixed it last night for my source region (us-east-1) and target region (us-east-2). I haven't tested other regions.

Now that the cross-region copy operation work the latency seems reasonable. I've observed about 3-4x the time it takes to create the snapshot.

Yeah I'd say that's a problem :-)

Depending on the Amazon Regions involved and the amount of data to be copied, a cross-Region snapshot copy can take hours to complete.

In some cases, there might be a large number of cross-Region snapshot copy requests from a given source Amazon Region. In such cases, Amazon RDS might put new cross-Region copy requests from that source Amazon Region into a queue until some in-progress copies complete. No progress information is displayed about copy requests while they are in the queue. Progress information is displayed when the copying starts.
