I want to do some testing for later use in our environment.
I have never performed a backup and restore before so I have quite a few doubts and confusions.
Before restoring, I have the option to set my content database, via central admin, to offline or even to remove it. Do I have to remove it or SharePoint will understand if I overwrite the current content database with a backup?
In the backup netBackup created we have some databases divided in one mdf and three ndfs, does that make any difference to SharePoint?
What measures should I take on the SharePoint site to make sure everything goes smooth?
