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.

To back up

Requires

Or

20 Meg

25 800K disks

143 140K disks

40 Meg

50 800K disks

286 140K disks

100 Meg

125 800K disks

714 140K disks

If the drives are not completely full, it will take fewer disks for the backup.
