Sonatype is looking through the archives and re-posting popular articles for those new to Sonatype tools.
The first blog in the series is by Sonatype software developer Juven Xu, on backing up Nexus.
Nexus is the industry leading repository manager that helps reduce build times and increase your control of open source artifacts by managing software artifacts required for development, deployment, and provisioning. Nexus greatly simplifies the maintenance of your own internal repositories and access to external repositories such as Maven Central. With Nexus you can completely control access to, and deployment of, every artifact in your organization from a single location.
If you are already using Nexus, this article will teach you how to back up your repository manager (if you don't use Nexus, you can click here for more information).
To backup Nexus simply means to make a copy of your Nexus files for safekeeping. The copy should be stored on different hardware, other than the original one. For example, you might want to copy your Nexus settings in the sonatype-work/nexus/config folder to a removable hard disk.
It is important to backup your Nexus files because sometimes things fail. Hard disk might crash, files might be deleted by other programs, even ourselves might delete important files by mistake. With a backup, you will be protected from these frustrating events.
