Copies an existing backup within the same Amazon Web Services account to another Amazon Web Services Region (cross-Region copy) or within the same Amazon Web Services Region (in-Region copy). You can have up to five backup copy requests in progress to a single destination Region per account.
You can use cross-Region backup copies for cross-Region disaster recovery. You can periodically take backups and copy them to another Region so that in the event of a disaster in the primary Region, you can restore from backup and recover availability quickly in the other Region. You can make cross-Region copies only within your Amazon Web Services partition. A partition is a grouping of Regions. Amazon Web Services currently has three partitions:
aws (Standard Regions),
aws-cn (China Regions), and
aws-us-gov (Amazon Web Services GovCloud [US] Regions).
You can also use backup copies to clone your file dataset to another Region or within the same Region.
You can use the
SourceRegion parameter to specify the Amazon Web Services Region from which the backup will be copied. For example, if you make the call from the
us-west-1 Region and want to copy a backup from the
us-east-2 Region, you specify
us-east-2 in the
SourceRegion parameter to make a cross-Region copy. If you don't specify a Region, the backup copy is created in the same Region where the request is sent from (in-Region copy).
