AWS Opens EBS Volume Clones To Copy Data Across Accounts
Amazon routes the copy through Resource Access Manager, holds it to the source's availability zone, and charges the receiving account by size.
- Channy Yun, AWS principal developer advocate, announced the feature on September 9, 2026.
- AWS-managed encryption keys block sharing; customer-managed keys allow it after re-encryption via KMS.
- Sharing through RAM costs nothing; the one-time size-based fee lands only on the receiving account.
Why it matters: Amazon built the account wall as a security feature and now charges to let you cross it.
