- You are correct about the cost of the diskettes themselves. However, there is
- a tradeoff in the support of the device used to backup the system. The 3.5
- inch floppy disk drive is standard equipment and is well supported by OS/2.
- Additionally, I can get Floppies very cheaply at the PX but I cannot get tapes.
- Further, if you go for a real cheap tape drive, you stand a chance that it will
- not be supported at some future date. I think that many people have had
- dealings with companies which produce a new piece of hardware and provide drivers
- to integrate it into an operating system. Later the company goes bottoms up for
- various reasons and now you have the hardware, no support, and no chance at
- getting updates to the drivers (or getting source code to recompile the drivers).
- The obvious argument here is that the tape drive is a one time investment, but you
- will quickly find out that it is not when it comes to updates. The hardware
- is a one time investment, but the software for future releases of an OS or for
- enhancements is often a cost item. Additionally, if the support for the backup
- device is not built directly into the operating system, when your system dies,
- you must first rebuilt the complete operating system, install the hardware
- drivers and updates, and then you can restore the information that you lost.
- That is time consuming. With a standard piece of hardware with driver support
- built into the OS, you only have to get a minimal system up in order to restore
- a system. Boot with floopy, restore with floppy and get going. Or just compromise
- and backup the OS partition with floppies and the rest with tapes.
-
- Additionally, if I have 10 386s which cost about 1500.00 each, I am not about
- to spend 500.00 per computer to add a tape drive. If I maintain all the systems
- identically and the only difference is the user area, I have made life a lot simpler
- with only floppies.
-
- By the way, the backup utility is worth 35.00. I paid over 70.00 for a backup
- utility from PcTools, so 35.00 makes it extremely attractive regardless of
- the media which it supports.
