CHAPTER FIVE
Backing Up the Vulcan

Introduction

Because Vulcan's partitions act as separate disks, you'll need to
backup the partitions separately.
We've included Apple Computer's Backup IL program on the
ProDOS partition of the Vulcan for backing up the ProDOS
partitions.
To back up the DOS 3.3, Pascal, and CP/M partitions, use an
appropriate backup program for those systems.

Backup II for ProDOS

Backup II is Apple's ProDOS volume backup program. It uses
the full 800K of 3.5" disks by segmenting the files to conserve
space. This means that if it is in the middle of copying a file
when it runs out of room on one disk, it finishes that file on the
next disk. When you restore, the segments are rejoined.
* Note: If you don't understand what pathnames, files,
folders, or directories are, please refer to A Brief ProDOS
Tutorial in the appendices of this manual.

Number of Disks Required

Refer to the chart below to determine about how many disks it
will take to back up your ProDOS partitions.
