[DXBase] Backup batch file

I am beginning to understand this.
First, I didn't realize that Windows has a built in back up program. 
But just checked in Win2K under Programs/Accessories/SystemTools and 
there it was. There is a help file with it that goes thru all the 
command line switches, which permit one to run it in a non-interactive 
fashion.
I have checked WinME and backup is not ordinarily provided, however it 
is on the WinME CD in the Add-ons subdirectory and you can install it, 
which I just did. The help however does not provide any information 
about command line switches, so I am going to assume that you cannot run 
it in a non-interactive fashion, and thus it would be useless in the way 
you describe. I am going to guess that Win98 has the same version. 
Looks like for these OS's you would have to find an independent backup 
program which allows command line switches and will execute 
non-interactively. Back4WinXP is available on the internet, costs 
25ドル.00 to register to use past 21 days, appears to provide command line 
switches to run non-interactivly, but I have not tried it. Back4WinXP 
also talks about detecting when a file has just been unassigned and then 
taking action, so there may be more than one way to use it.
I don't have WinXP here, but called a friend who searched for 
ntbackup.exe and it was there, so Ill assume that XP has the same backup 
program installed as does Win2K.
Secondly I didn't realize that I could still use Batch files in Windows, 
like I did in DOS, but low and behold they still work. Best yet you can 
build them and then put them on the desk top as shortcuts and execute 
them. So for the example you gave that batch file could be on the 
desktop ready to be 'clicked'.
So in brief it looks like we have the tools to automatically backup just 
the 'user' files in DXBase, in a way that will allow you to 
store/retrieve a complete history of your data base files, limited only 
by the storage space you are willing to use.
No guarantee when I will get to setting this up...if someone does so 
first please post it here.
