So, let’s find out how to obtain a Windows TFTP server. You really want your Cisco device backups on a PC or server that can be backed up to tape. However, storing your backups on a router isn’t the best idea. You can make a Cisco router a TFTP server and copy files from other routers to that router. However, because UDP doesn’t use any kind of acknowledgements, it is also faster than TCP. Because it uses UDP and UDP is connectionless, TFTP file transfers are not meant for networks with a lot of latency, like the Internet. TFTP uses UDP, not TCP for transferring of files (like FTP does). TFTP stands for Trivial File Transfer Protocol. To prevent this, make sure you backup your configurations with TFTP. You don’t want your router to crash one day, get a replacement, and spend days trying to recreate the configuration file. Just like any important server on your network, Cisco routers and switches need to be periodically backed up.
