Answer 1

Yes. You can optionally configure vaults to send notifications to you or your application when jobs complete. Notifications will be delivered via the Amazon Simple Notification Service (Click here to learn more about Amazon SNS).

Question 2

What are data retrieval policies?

Answer 2

Amazon Glacier data retrieval policies let you define your own data retrieval limits with a few clicks in the AWS console. You can limit retrievals to “Free Tier Only”, or if you wish to retrieve more than the free tier, you can specify a “Max Retrieval Rate” to limit your retrieval speed and establish a retrieval cost ceiling. In both cases, Amazon Glacier will not accept retrieval requests that would exceed the retrieval limits you defined. Retrieval policies apply to Standard retrievals.

Question 4

Are data retrieval policies specific to each AWS region?

Answer 4

Yes. You can set one data retrieval policy for each AWS region which will govern all data retrieval activities in the region under your account. Data retrieval policies are region-specific because data retrieval costs vary across AWS regions.

Question 5

Can I use data retrieval policies to “slow down” my retrievals or spread them out?

Data Retrieval Policies

Answer 5

No, data retrieval policies such as “Free Tier Only” and “Max Retrieval Rate” will not accept a data retrieval request which would exceed your predefined data retrieval limit to help you manage data retrieval cost. Data retrieval policies will not change the 3 to 5 hour data retrieval latency or spread out your retrievals. You can leverage Amazon Glacier’s range retrieval feature to spread out retrievals and lower the peak retrieval speed. Learn more.
