Hi EE.

i need a little help for a simple script.

Wants to some folders to be incremental backup

From C:\App -> E:\App
From C:\List -> E:\App.

I have worked a bit with my own script, but cant get it to work 100 %.

If i delete a file in C:\App the file also should be deleted in E:\App

Thank you

I would use the following delta copy utilty for this.  when set up correctly it will synchronise the destination and source folders automatically and is very efficient at copying the files.

Normally, you would use a tool like robocopy  to perform such a synchronization.

Robocopy.exe c:\app e:\app /mir

The culprit however is that you are trying to synchronize from two directories to one. Robocopy will mirror the entire directory, thus with the above command deleting everything that originally came from C:\list

A solution could be devised if the filenames in C:\app and c:\list are sufficiently different that the filenames that are found in c:\list can be excluded in the robocopy command from c:\app, and vice versa.

for instance:

robocopy c:\app e:\app /mir /XF *.lst
robocopy c:\list e:\app /mir /XF *.exe


robocopy can be found here:

Robocopy is a good tool and works similarly to deltacopy. The main difference is that robocopy copies the entire file every time it detects a change whereas deltacopy will only copy changes to the file.  If you have large files in which only a small parts are changed then deltacopy can be very efficient.

HP11103174822::Villadsenssmedie      /util/

This doesn't right if you are copying to a remote machine.

See the following link for how to specify the connection.

HP11103174822 can be found without full domain name?

Villadsenssmedie is configured as a virtual directory on the receiving server?

Apologies, I don't quite understand.

what is the difference between a set up that works on your machine, and the setup that doesn't work

Very nice app indeed.

And does it handle the two sources - one destination conflict without removing files?
