Adam:

I read with very much atention your post and Helen´s post and they were really useful for me. I am very grateful to you because of that. Helen was not too subtle :-) I know that I don´t have to use mapped drives to access a Firebird database and I promise you (and of course Helen) that I won´t do it. :-)

With the examples of gbak statements in my previous post I only wanted to show that I tried many posibilities just to see which one worked right. I repeat that I understand that I must not use mapped drives to access a database. I also wanted to show that if I want to make a backup of a local database, and generate the FBK file in a network drive, I can do it writing the location of the FBK file (I repeat, the FBK file, not the FDB file) using a mapped drive. Is this a bad thing too?

About the statement

gbak -t -v -user SYSDBA -password <password> "PC2:C\MyDataBases\MyDB1.FDB" "C:\MyBackups\MyDB1.fbk"

it works perfectly. You say that it will not work because you say PC2 is the PC which has the embedded server. This is my fault because I confused the names of the PCs. This PC2 is just the server PC, so I should have call it PC1 as in my firs post. So the right statement (executed from the client PC2) is:

gbak -t -v -user SYSDBA -password <password> "PC1:C\MyDataBases\MyDB1.FDB" "C:\MyBackups\MyDB1.fbk"

I apologize for the confusion.

So now I only have the question I made in my previous post about the way to call Firebird-2.0.1.12810-0-Win32.exe (or another file) with any parameters, to copy the files I need or, in another words, to install the embedded server in the way I need. Is there a way to do that?

This is a very confusing subject (at least for me :-)), so if you think I am doing something wrong, please tell me.

Gustavo
