Hi all,

I'm going to create a local mirror using information found on: https://wiki.centos.org/HowTos/CreateLocalMirror

From the I know that I could use reposync or an rsync script to sync my mirror. But I'm not sure what the pros and cons of either method are.

As far as I know I have to choose one specific mirror nearby when using rsync. If this mirror is not available I have to change my script to use another one.

Using reposync I guess it would choose the fastest mirror from the configured yum repos of my installation.

Please correct me, if I'm wrong in my assumptions.

Maybe in the future I would like to provide a public mirror. Is there any preferred sync method for this scenario?

For public mirrors you should use rsync. reposync will not sync non-rpm files, such as .iso images. Using reposync would also break the signed metadata (repomd.xml.asc), and arranging the mirror layout would be unnecessarily difficult with reposync. Reposync doesn't know about hard links either. So the tool to use for public mirrors is rsync.

For a private mirror either one will work, but I prefer using rsync for my own private mirror due to the layout matching what is on other mirrors. The upstream mirrors won't change that often, so I don't think you would need to change that URL that often. And if you're planning to provide a public mirror at some point, I'd suggest going straight to rsync and skipping reposync.

If you don't need all the files from the mirrors, you can --exclude them, like --exclude '*/cloud/*'

You may want to use -v --dry-run first to see which files would get transferred.

Thank you both vor your answers. I'm going with rsync then.

Thanks, Joerg
