I have a large networked file system whose backup routine sees some file systems as higher priority than others and are given more redundancy with backups. At present those file systems are visible as separate drives to users via SAMBA, but share high and low priority amongst projects. For example, a simulation input file for a project is generally both small and important to keep. The result file is very large and with compute power easily regenerated. These files would ideally be kept in separate file systems that have matching directory structures, and presented to the user through a single continuous directory structure as though there were stored in the same physical location. What would be required to do this?Asked another way, is there a way of making the backup strategy and priority invisible to the user?I am running a CentOS 7 based server.
Is there a way to interleave two filesystems of the same structure?
