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.
