We have an IIS FTP server with file zillia client (windows server 2008 R2), which is used to transfer some files to a partner organisation. Currently the server is not backed up. It doesn't host any permanent data, only temporary files used to transfer which are then no longer serving any operational purpose. I am not responsible for backups, but our admins claim it is just as quick to rebuild the system from scratch as it would be to restore.
Is there any value in backing up such a server, where there is no permanent user data on there? Realistically how easy would it be to re-configure an FTP server and all relevant connections, does this alone warrant backup, or is it very simple to reconfigure and therefore is the admins view correct and valid?
