I arrived at that conclusion by trying them both. However, I arrived at it before I wrote this comparison, so it comes off sounding biased. I do not apologize for that. Colorado Jumbo 250 streaming tape drive, with floppy interface. Installation BackMaster is distributed on one floppy disk.
Installation is flawless.
You insert the disk, click install, give it a directory, and installation proceeds. The program must install a driver into config.sys, and permission to do is is requested before proceeding. Rebooting is required to activate the driver. All files are installed into the BackMaster directory, and the installation takes up about 1 megabyte of hard disk space. I have tried it each way, and never found it to make any difference.
