What if something goes wrong ?              Just a stupid question: but are there no test machines to which you       can restore a backup? This has a number of advantages:              1) You are testing that your backup works.       2) You run DBCC in an offline environment.       3) You are testing that your restore works as well.              I have experienced cases where DBCC did not report errors on the live       database, only when I had restored it. (I should hasten to add that this       was with SQL 6.0, loooong ago.)              You said this was a 24/7 shop and if they don't have spare machines or       a disaster plan, I get scared.              When running on a live database, you may prefer to use PHYSICAL_ONLY to       reduce the impact.              You should really run a full CHECKDB on the new server, before you take       it live. But you can do that while the old machine is still the production       server.              --       Erland Sommarskog, SQL Server MVP, esquel@sommarskog.se              Links for SQL Server Books Online:       SQL 2008: http://msdn.microsoft.com/en-us/sqlserver/cc514207.aspx       SQL 2005: http://msdn.microsoft.com/en-us/sqlserver/bb895970.aspx       SQL 2000: http://www.microsoft.com/sql/prodinfo/previousversions/books.mspx              --- SoupGate-Win32 v1.05        * Origin: you cannot sedate... all the things you hate (1:229/2)    |
