<a name="bp-migrating-table-between-accounts-backup"></a>

**Prerequisites**
+ Source and target Amazon accounts must belong to the same organization in the Amazon Organizations service
+ Valid Amazon Identity and Access Management (IAM) permissions to create and use Amazon Backup vaults

For more information about setting up cross-account backups, see [Creating backup copies across Amazon accounts](https://docs.amazonaws.cn/aws-backup/latest/devguide/create-cross-account-backup.html).

**Pricing information**

Amazon charges for the backup (based on the table size), any data copying between Amazon Regions (based on the amount of data), for the restore (based on the amount of data), and for any ongoing storage charges. To avoid ongoing charges, you can delete the backup if you don't need it after the restore.

For more information about pricing, see [Amazon Backup pricing](https://www.amazonaws.cn/backup/pricing/) .
