After you customize the OpenVMS operating system to your
satisfaction and perform the other steps recommended thus far in this
chapter that are relevant to your system, protect your work by making
a standalone backup copy of the system disk to tape. To do so, follow
the instructions in Section 7.2. If you are going to be saving to disk, specify a disk that will
not be (or is not) part of a shadow set.
For complete information about backup operations,
including a description of an alternative method that does not require
booting from the operating system media, see Appendix F.
HP also recommends creating a systematic routine
for backing up the application, data, and user disks. For more information,
see the HP OpenVMS System Manager's Manual, Volume 1: Essentials.
