You can now use Identity and Access Management (IAM) condition keys to specify which resource types are permitted in the retention rules created for Recycle Bin . With Recycle Bin, you can retain deleted EBS snapshots and EBS-backed AMIs for a period of time so that you can recover them in the event of an accidental deletion. You can enable Recycle Bin for all or a subset of the Snapshots or AMIs in your account by creating one or more retention rule. Each rule also specifies a retention time period. A deleted EBS snapshot or de-registered AMI can be recovered from the Recycle Bin before the expiration of the retention period.
