SQL Server Database Backup


Sometimes things that seem complicated are much easier then you think and this is the power of using T-SQL to take care of repetitive tasks.  One of these tasks may be the need to backup all databases on your server.   This is not a big deal if you have a handful of databases, but I have seen several servers where there are 100+ databases on the same instance of SQL Server.  You could use SQL Server Management Studio to backup the databases or even use Maintenance Plans, but using T-SQL is a much simpler and faster approach.


With the use of T-SQL you can generate your backup commands and with the use of cursors you can cursor through all of your databases to back them up one by one.  This is a very straight forward process and you only need a handful of commands to do this. 

How to Backup All SQL Server Databases

  1. Specify path to store database backups
  2. Specify backup file name format
  3. Select list of databases to backup
  4. Loop through databases
  5. Programmatically create database backup command using database name, path and file name format
  6. See attached SQL Server backup script

File Naming Format DBname_YYYYDDMM.BAK

Here is the script that will allow you to backup each database within your instance of SQL Server.  You will need to change the @path to the appropriate backup directory.


In this script we are bypassing the system databases, but these could easily be included as well.  You could also change this into a stored procedure and pass in a database name or if left NULL it backups all databases.  Any way you choose to use it, this script gives you the starting point to simply backup all of your databases.

Also, if you wanted to bypass some of your user databases you can include them in the NOT IN section as well.

This file needs to be saved, and changed to .SQL for it to properly compile.
