24.11. ConclusionCompanies of all sizes must ensure that they are taking care of all parts of the data protection landscape that pertain to them. Unfortunately, the open-source projects that have enabled this book to exist have not yet embraced the archive, security, and disaster recovery elements of data protection in the same way they have embraced backup and recovery. While some aspects of archiving, security, and disaster recovery have been addressed in some open-source projects, we don't yet have open-source answers to the commercial products that are addressing today's archiving, security, and disaster recovery needs. Once we have open-source email archiving products, line-speed encryption products, or full-scale block-level replication products, it will be time for another edition of this book. For now, I hope this book has been helpful.
