Abstract
Techniques are described for efficient and secure key rotation for backup storage. An example method comprises generating, by a data platform implemented by a computing system, a first encrypted key and a second encrypted key, wherein the data platform stores one or more encrypted chunks encrypted using a first encryption key of the first encrypted key and a second encryption key from the second encrypted key, the first encrypted key and the second encrypted key encrypted with a first system key, replacing the first system key by determining a second system key, and encrypting, with the second system key, the first encryption key to generate a replacement first encrypted key and the second encryption key to generate a replacement second encrypted key.
