DB Backup and Restore with Differential backups

--Taking Backup

--Step1:

BACKUP DATABASE TestDBMain TO DISK = 'C:\Temp\DatabaseBackups\TestDBMain_FullB.bak'

GO

--Step2:

--Create some test table and insert some Rows

--Step3:

BACKUP DATABASE TestDBMain TO DISK = 'C:\Temp\DatabaseBackups\TestDBMain_DiffB_1.bak' WITH DIFFERENTIAL

GO

--Step4:

--Insert Some more rows

--Step5:

BACKUP DATABASE TestDBMain TO DISK = 'C:\Temp\DatabaseBackups\TestDBMain_DiffB_2.bak' WITH DIFFERENTIAL

GO

--Step4 and Step5 Can be repeated as many time

-------------------------------------------------------------------------------------------------------------------------------------

-------------------------------------------------------------------------------------------------------------------------------------

--Restore DB First Time

--Step1:

--Create TestDB1 using UI . Pointing MDF and LDF as shown below, And without 'NORECOVERY' command

--Step2:

RESTORE DATABASE TestDB1

  FROM DISK = 'C:\Temp\DatabaseBackups\TestDBMain_FullB.bak'

  WITH REPLACE,

  MOVE 'TestDBMain' TO 'c:\temp\DatabaseBackups\TestDB1\TestDB1.mdf',

  MOVE 'TestDBMain_log' TO 'c:\temp\DatabaseBackups\TestDB1\TestDB1.ldf';

GO

-------------------------------------------------------------------------------------------------------------------------------------

--Restore DB Second Time

--Step1:

--Create TestDB2 using UI . Pointing MDF and LDF as shown below, And with 'NORECOVERY' command

--Step2:

RESTORE DATABASE TestDB2

  FROM DISK = 'C:\Temp\DatabaseBackups\TestDBMain_FullB.bak'

  WITH NORECOVERY,REPLACE,

  MOVE 'TestDBMain' TO 'c:\temp\DatabaseBackups\TestDB2\TestDB2.mdf',

  MOVE 'TestDBMain_log' TO 'c:\temp\DatabaseBackups\TestDB2\TestDB2.ldf';

GO

--Step3:

RESTORE DATABASE TestDB2 FROM DISK = 'C:\Temp\DatabaseBackups\TestDBMain_DiffB_1.bak' WITH RECOVERY

GO

-------------------------------------------------------------------------------------------------------------------------------------

--Restore DB Third Time

--Step1:

--Create TestDB3 using UI . Pointing MDF and LDF as shown below, And with 'NORECOVERY' command

--Step2:

RESTORE DATABASE TestDB3

  FROM DISK = 'C:\Temp\DatabaseBackups\TestDBMain_FullB.bak'

  WITH NORECOVERY,REPLACE,

  MOVE 'TestDBMain' TO 'c:\temp\DatabaseBackups\TestDB3\TestDB3.mdf',

  MOVE 'TestDBMain_log' TO 'c:\temp\DatabaseBackups\TestDB3\TestDB3.ldf';

GO

--Step3:

RESTORE DATABASE TestDB3 FROM DISK = 'C:\Temp\DatabaseBackups\TestDBMain_DiffB_1.bak' WITH NORECOVERY

GO

--Step4:

RESTORE DATABASE TestDB3 FROM DISK = 'C:\Temp\DatabaseBackups\TestDBMain_DiffB_2.bak' WITH RECOVERY

TFS Add Work Item Column

1) Get List of WorkItem:

     witadmin listwitd /collection:http://XXXXXX/tfs/DefaultCollection /p:ProjectName

2) Export Specific WorkItem Type from the List:

     witadmin exportwitd /collection:http://XXXXXX/tfs/DefaultCollection /p:ProjectName/f:C:\TFS\WorkItem\Product_Backlog_Item.xml /n:"Product Backlog Item"

3) Edit the xml in VS 2015 it will open Eork Item Editor

4) Add Custom Columns ( StartDate -- Custom.StartDate, End Date -- Custom.EndDate)

5) Set the Layout where the colum should display

6) Save the WorkItem Template

7) Validate the WorkItem template

     witadmin importwitd /collection:http://XXXXXX/tfs/DefaultCollection /p:ProjectName/f:C:\TFS\WorkItem\Product_Backlog_Item.xml /v

8) Import the WorkItem template (by removing /v in previous command)

    witadmin importwitd /collection:http://XXXXXX/tfs/DefaultCollection /p:ProjectName /f:C:\TFS\WorkItem\Product_Backlog_Item.xml

What to DB if DB Goes Suspect Mode ?

--First Check the auto recovery status may be the DB will be in recovery mode 

--xp_readerrorlog

--IF Db not in recovery mode and it is Suspect mode

-- Execute the below query line by line after removing comments
-------------------------------------------------------------------------------------------------------------------

--EXEC sp_resetstatus 'dbname';

--ALTER DATABASE [dbname] SET EMERGENCY

--DBCC checkdb('dbname')

--ALTER DATABASE [dbname] SET SINGLE_USER WITH ROLLBACK IMMEDIATE

--DBCC CheckDB ('dbname', REPAIR_ALLOW_DATA_LOSS)

--ALTER DATABASE [dbname] SET MULTI_USER

--DBCC CheckDB ('dbname')
