Save time (and money) on data transfers between hosts withrsync, a synchronization tool that allows easy, efficient replication offiles between different locations. Sync up, now!
And that's about it. Over the course of this article, I introduced you to rsync, an extremely powerful utility for file synchronization between hosts. I showed you how to synchronize files between directories on the same machine, and also between different hosts on a network. I also demonstrated the process of configuring an rsync server, with examples of both anonymous and authenticated access, and showed you how you could perform your file transfer within an SSH connection for greater security. Finally, I illustrated how all this theory could be put to practical use with examples of how rsync could be used in common real-world situations involving file backup and mirroring.
