When you backup an encrypted database, the backup file contains encrypted blocks. As blocks are written to the backup file, they are encrypted with the current encryption policy. To guarantee that the blocks are backed up with the current encryption policy, there can be no policy changes while the backup is running.

If you restore an encrypted database from backup with -newinstance, you will not be able to open the restored database until you rebind the key store with PROUTIL EPOLICY MANAGE KEYSTORE REBIND. For the complete syntax, see PROUTILEPOLICY MANAGE qualifier.
