If you are maintaining a production SQL Server, then you might be using a Maintenance Plan or an SQL Server Agent Job to automate the regular database backup process. However, once in a while, you might need to backup all the databases in the server for some reason like an unplanned maintenance task. In such situations, a Transact SQL script to backup all the databases will come in handy. Here is the TSQL script I use:
The input for this script are:
- Path to store the DB backups.
- List of databases to be excluded.
Script To Backup All The Databases
DECLARE @bk_path VARCHAR(256); DECLARE @db_name VARCHAR(50); DECLARE @bk_file_date VARCHAR(20); DECLARE @bk_file_name VARCHAR(256); DECLARE @i INT = 1; /* Specify database backup directory. Change this as needed. */ SET @bk_path = 'C:\Backup\'; /* Backup file format DBname_YYYYMMDD_HHMMSS.BAK. Change this as needed. */ SELECT @bk_file_date = FORMAT(GETDATE(), 'yyyyMMdd_hhmmss'); DECLARE @db_names TABLE ( id INT IDENTITY(1,1) PRIMARY KEY, db_name VARCHAR(50) NOT NULL ); INSERT INTO @db_names SELECT name FROM master.sys.databases WHERE name NOT IN ('master','model','msdb','tempdb') /* Databases which needs to be excluded */ AND state = 0 /* Include only the database which are online */ AND is_in_standby = 0; /* database is not read only for log shipping */ WHILE EXISTS (SELECT 1 from @db_names WHERE Id = @i) BEGIN SELECT @db_name = db_name from @db_names WHERE Id = @i; PRINT 'Backup Started: ' + @db_name SET @bk_file_name = @bk_path + @db_name + '_' + @bk_file_date + '.BAK'; BACKUP DATABASE @db_name TO DISK = @bk_file_name WITH STATS; SET @i = @i + 1; END GO
