How to Backup all Database in SQL server using query

Why Database backup is important?

An error can arise when trying to write or read a file that is required to operate the database. This is called disk failure because there is a physical problem reading or writing physical files on disk. A common example is a disk head crash, which causes the loss of all files on a disk drive. So database backup is important.

Step 1:

First open the sql management studio.

Step 2:

Login the sql management studio using credentials.

                                       

Step 3:

Select the database tab in left side panel.

                                       

Step 4:

Click new query button in the left corner of the page.

                                       

Step 5:

Enter the all database query in the query page.

                                       

Step 6: 

Change the database storing location in the query.

                                       

Step 7:

Click execute for run the query

Step 8:

Finally query executed successfully

(All database backup Query)

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

-- please change the set @path = 'change to your backup location'. for example,
-- SET @path = 'C:\backup\'
-- or SET @path = 'O:\sqlbackup\' if you using remote drives
-- note that remotedrive setup is extra step you have to perform in sql server in order to backup your dbs to remote drive
-- you have to chnage you sql server accont to a network account and add that user to have full access to the network drive you are backing up to

SET @path = 'D:\backup\'  --set your backup path

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')

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
