Generally we face a problem when we want to upgrade our sql server management studio version , all the databases are lost. To take all database backup one by one is completely irritating.
To overcome this irritating job , our sql provides a great solution to take all database backup very easily by writing few lines of sql. I applied it on my sql server 2008 R2 version and i really like this task because of my job completion within few seconds.
Now its time to see that what sql lines of code can make you happy.
DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
-- specify database backup directory
SET @path = 'D:\Backup\'
-- specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name NOT IN ('master','model','msdb','tempdb') -- exclude these databases
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
BACKUP DATABASE @name TO DISK = @fileName
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor
