Bitnami redmine for windows backup and recovery

Hi,

I have just read about how to backup and recover bitnami redmine for windows. I just only have One question: Below is the guide which i found on the previous forum:

1. If you want to backup the whole Stack.

This method is very quick and let you move your Redmine application to another Windows machine easily.

• IMPORTANT: Stop the servers. You can stop the servers using the shortcut or you can stop the services in the Windows service panel ( you can type in a command prompt “services.msc”). The name of the services are redmineApache, redmineMySQL and redmineMongrel. It is possible that you have more than one Mongrel.

• Once you have stopped the services, copy your installation directory in a USB, CD or to the other machine directly. It is important that the installation directory is the same in the new machine. For example if you have installed the Stack in C:\Program FIles\BitNami Redmine Stack, this is the same location where you should copy the backup in the new machine.

• Install the services in the new machine. Go to a command prompt and type:

  cd “C:\Program Files\BitNami Redmine Stack” servicesinstall.bat INSTALL

Now my question is, do I need firs to install the redmine application before executing the batch file?

Thanks in advance for the help.
