+====
+The configuration of the Kopia algorithms for splitting, hashing, and encryption in the Data Protection Application (DPA) apply only during the initial Kopia repository creation, and cannot be changed later.
+
+To use different Kopia algorithms, ensure that the object storage does not contain any previous Kopia repositories of backups. Configure a new object storage in the Backup Storage Location (BSL) or specify a unique prefix for the object storage in the BSL configuration.
