[DX4WIN] Backup Of Logbook to Floppy

[Larry Alkoff]

I backup my log _files_ frequently to several hard disks on my home network
using a simple dos batch file.  It's just a matter of typing "backn2la".

We have a shack computer, my office computers (Windows 98 and Linux) and wife's office computer.
They all have to fail before I lose the data.

I say _files_ because it is necessary to backup n2la.dxl, dx4win.tcp and dx4win.cty.
They all are zipped into n2la.zip in the save directory of DX4Win on the shack computer with zip -u.

Then the zip files are saved to several networked computers (including the shack computer) in /data/ham.dat
as n2laDOY?.zip where DOY is the Day Of the Year and ? is a single letter from a to n.
The backup file names for any given DOY start with a and continue to n such that, if n2la309a.zip exists then
the next is named n2la309b.zip etc.

The batch file runs under 4DOS, a command.com replacement which has the DOY function
but it should be easy to do something under command.com.  Of course, if you do much batch work
I strongly suggest 4DOS which has many extensions to make like under dos better.
Use 4NT for the CLI of Windows NT - actually it runs in 32 bits under _any_ Windows 95+ OS.

At present 1.4 megabytes of data take under 400k of disk space - it's cheap you know.

The next thing I'm going to do is make it run once daily automatically but I don't know how to do this under Windows 98 yet.
There is no cron.daily you know ;-)

Since attachments are not permitted on this list,
I have included the batch file for your inspection:

===============  batch file backn2la.bat   =======================================

@echo off
rem Copy n2la log data from n2la computer to wanda

pushd c:\pf\ham\dx4win\save

echo Updating n2la.zip file:
