If you plan to version files from one or more encrypted source volumes, the archive volume must also be an encrypted volume. Otherwise, the data is stored nonencrypted on the archive volume.
For information about NSS Encrypted Volume Support, see Managing Encrypted NSS Volumes in the OES 2: NSS File System Administration Guide.
The data is not secure when transported between the source volume and the archive database. For information, see Section 5.2, Secure Data Transfer.
