I have created kind of “part 2” of my previous screen-cast (How SnapMirror works). In this one I start with already existing snapmirror relationship between primary and secondary site. I have written short batch file that is simulating business critical application, which is, of course, using NetApp share. Once the application is up-and-running I simulate the ‘disaster’ of primary site and show you how you can recover from disaster, using your DR (secondary) site, together with SnapMirror technology.
Did you come accross with my entry SnapVaul vs SnapMirror ? In this one I mentioned that SnapMirror is a great DR solution, although it is not a backup solution. I decided to create a quite short screen-cast explaining how to set up SnapMirror, and give you an example how it works. I’m planning to do a follow-up video (maybe next Monday or Tuesday?) of Business Continuity case study, with some simple scenario that will include reversing the SnapMirror relationship, and later on re-syncing it back. But for now please watch my 20 min+ screen-cast about the SnapMirror basics. As always all comments are most welcomed!
If you want to have a better understanding of Snapshots you can watch my new screen-cast:
In this one instead of a theory I’m trying to show you (based on a real-time examples) how snapshots work – how restore data, etc.. But also – what Storage Engineer has to remember, when dealing with snapshots. This video is based on NetApp (7-mode) and one CIFS share accessed from Windows.
