How To: Best way to Back Up and Restore many DBs ?

Question

Hi Forum,
I have 200 databases (SharePoint databases) that are running on one single instance e.g. (Server1\Instance1), and the names of the databases are e.g.: (DB1, DB2, DB3....DB200).
I want to migrate all these 200 databases to another instance e.g. (Server2\Instance2).
Of course, I can use the SSMS to Back Up and Restore the databases, But, For 200 databases, This is quite impractical.
Therefore, I have two questions:
1) Which option is the safest way to Back Up 200 databases which their sizes combined together could be around 80 GB? Using T-SQL or Maintenance Plan? Obviously, I want a process that doesn't hang or fail.
2) I found the script below on: (http://www.mssqltips.com/sqlservertip/1070/simple-script-to-backup-all-sql-server-databases/) - Is it excellent script? Any better script?, Also, Could you please tell me how to keep the exact name of the databases
without any changes at all (Without appending date nor time)?
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
-- Back Up Directory
SET @path = 'E:\Backup\'  
-- 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
3) Any script for restoring all these databases from the Backup directory to the new SQL Server instance (Server2\Instance2) ?

Answer 1

You would have to develop the script for a single database move, test it thoroughly, then write the dynamic SQL WHILE loop.
At any rate, this appears like a good task for an experienced DBA
and not for a Data Architect.
Here is another example for a dynamic SQL WHILE loop:

PowerShell is another alternative:
Copy user databases to a different server with PowerShell
