I was just wondering if these would be sufficient to restore a system database, or whether we would need BAK files instead (we are already creating them, they're just not as easily to hand as the MDF and LDF copies!)ThanksTue, 09 Oct 2012 05:41:40 GMTmatt.gytonhttp://www.sqlservercentral.com/Forums/Topic1370328-391-1.aspxI have, in the past restored a master database to anohter instance as a user database, then detached it and renamed the disk files to their original names and then plugged them into the original instance. I have done this for master model and msdb.What is the particular problem you ae trying to resolve?Tue, 09 Oct 2012 05:31:46 GMTPerry Whittlehttp://www.sqlservercentral.com/Forums/Topic1370328-391-1.aspxHi all,Is it possible to restore a Master database onto a new server (with identical build) using just copies of the MDF and LDF files from the old server? Or do you need a full backup of the Master?...and also is it possible to do it this way for the MSDB?Thanks,MattTue, 09 Oct 2012 05:27:10 GMTmatt.gyton
