>>>Hi All,
>>>
>>>Given two geographically seperated web servers with http and ftp capability and running Windows Server, how can I keep them mirrored in terms of folders and files? i.e. updates I make to one server in respect of adding new files or changing existing files must be mirrored to the other server. This does not have to be real time. A batch job once per day / week or on demand would suffice. Any suggestions for tools that do this, either commerical or other?
>>
>>Do the servers have a master-slave relationship, or are they peer-to-peer? IOW do you only have to copy updates etc. from a master to a slave, or are updates being done separately on both servers and you have to reconcile them somehow?
>>
>>Are you talking strictly about unshared files and folders, or could there be shared/open files (e.g. VFP, SQL Server, Exchange Server, ...)?

I need a way to copy updated files from the live to the backup without wasting time copying things that have not changed. This can be a daily batch job. I need a solution that works over TCP/IP using either HTTP or FTP protocol.

Jos,

Can you mount the backup drive, ie can you make it a network drive ? If so, have a look at robocopy. It only copies files that have changed and also deletes file that are no longer there. You can easily make a batch file and put that in the task scheduler
