Recursive T-SQL Backup All Databases Script

I had this script running as a job on my production server.

I had to modify this script to include a TRY-CATCH block so that if a backup command failed it will continue on to the next database and not exit the script. This was an issue with the script that I had to resolve. 

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 = 'C:\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'
BEGIN TRY BACKUP DATABASE @name TO DISK = @fileName END TRY BEGIN CATCH -- Execute error retrieval routine. EXECUTE usp_GetErrorInfo; END CATCH FETCH NEXT FROM db_cursor INTO @name END CLOSE db_cursor DEALLOCATE db_cursor
