The Importance of Making Backups or, How to Get Out of a Strawberry Jam
Brian Staples · OCLC Micro · 1985
Somewhere in its first few pages every good software manual stresses the importance of making backup copies of program and data disks. In the OCLC M300 Guide to Operations, 2d ed., the instructions for making backup copies are in Chapter 2, section 2.3.1. In the DOS manual (version 2.00) they're on pages 3–10 through 3–29.
