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: zip -u n2la n2la.dxl dx4win.cty dx4win.tcp copy /u \\n2la\c\pf\ham\dx4win\save\n2la.dxl \\wanda\c\pf\ham\dx4win\save\ copy /u \\n2la\c\pf\ham\dx4win\save\dx4win.cty \\wanda\c\pf\ham\dx4win\save\ copy /u \\n2la\c\pf\ham\dx4win\save\dx4win.tcp \\wanda\c\pf\ham\dx4win\save\ rem Change to dx4win\save\backup if not isdir \pf\ham\dx4win\save\backup md backup cd backup set numb=a if exist n2la%_doy%a.zip set numb=b if exist n2la%_doy%b.zip set numb=c if exist n2la%_doy%c.zip set numb=d if exist n2la%_doy%d.zip set numb=e if exist n2la%_doy%e.zip set numb=e if exist n2la%_doy%f.zip set numb=g if exist n2la%_doy%g.zip set numb=h if exist n2la%_doy%h.zip set numb=i if exist n2la%_doy%i.zip set numb=j if exist n2la%_doy%j.zip set numb=k rem skip number l if exist n2la%_doy%k.zip set numb=m if exist n2la%_doy%m.zip set numb=n echo Updating log data to n2la and wanda: copy /u ..\n2la.zip \\wanda\c\inv\ham.dat\dxlog\n2la%_doy%%numb.zip copy /u ..\n2la.zip \\wanda\d\inv\ham.dat\dxlog\n2la%_doy%%numb.zip copy /u ..\n2la.zip \\doug\c\inv\ham.dat\dxlog\n2la%_doy%%numb.zip copy /u ..\n2la.zip c:\inv\ham.dat\dxlog\n2la%_doy%%numb.zip :end popd ============= end batch file ============================= Larry Alkoff N2LA - Austin TX
