The previous post focused on Veritas backup products, but don't forget Veritas has many other products as well. I am willing to beat most sites are looking for Netbackup, BackupExec, or Veritas Filesystem/Foundation Suite. Unfortunately I don't think you will be able to find a free product that will give you the same experience as working with Veritas products. The principles may be the same but the commands and terminology will be different.
