Considering Database Encryption Considering Database Encryption When you restore a database on a target system, it may be necessary to change the database encryption key for the restored database. Depending on the strategy you used to back up the database, you may have to convert the key on the restored database, as follows: For Online Backup — Online backup stores the database contents unencrypted. When restoring an online backup file to an existing encrypted database on a target system, the online backup restore utility encrypts the file dynamically on the target system; otherwise the restored database is unencrypted. For External Backup, Cold Backup or Concurrent External Backup — Depending on the state of the IRIS.DAT file on the source system, you may need to manage the database’s encryption after restoring it on the target system; for example, if the database files on the source and target systems use different encryption keys, you activate the key from the source on the target (see Key Management Tasks), or convert the restored database to use the key on the target (see Convert an Encrypted Database to Use a New Key).
