NIM vs. SysBack for DRP
We recently performed a DR test and one business group decided to use a NIM server to rebuild their systems for the test. This meant taking the local NIM server and having to restore it then restore the individual clients, meanwhile us TSM admins sat around twiddling our thumbs waiting for them to finish (for some reason the system images and NIM are handle by the System Administrators group and not the Backup/Recovery group). I would have preferred SysBacks (since we are an AIX shop), but the SA had this brilliant idea to use NIM. This added another layer of complexity and actually due to disk issues it took forever to get the NIM server running. I would like feedback on what others have done for their DR tests, and if anyone has experience with the TSM integrated SysBack feature I would love to hear how it works for you.
