Sometimes you click something inoculus, and the world ends.
The button was not red, and it didnt have a safety cover.
Yet it did something really bad, and totally unexpected.
Had that happen to me this morning. Shutdown a file server,
and the datastore was gone. I understand why, as I was moving data
off the datastore, but I didnt expect it to go at that point.
What to do Now !?!?!
We had updated to Veeam 5.0 Vmware backup few months ago.
I decided to give it a try, as I had a backup from just hours ago
and no data had been updated.
I traditional tape, a restore is a multi-day affair with logs of downtime
and other unplesant activity.
With Veeam I still expected a 5-8 hour downtime as veeam did the restore.
Instead I decided to use the Instant Recover Mode. From start to having the
server running again was 2 minutes counting boot time. The Restore only took a minute and a half. At that point the server was running over a
virtulized nfs server automatically attached to the blade of my choice,
automatically added to my vcenter, and automatically started.
For the non-believers I've included a screen shot just to prove the point.
The server in question has been running now most of the day without issue
and its 60% migrated back to production storage using Storage vMotion.
This is really unbeliveable how well and easy it worked.
