It is an optional tool to use SQL Server Maintainence Plan to schedule regular backups of your databases. To take advantages of full control, total flexibility, I use my own scripts to backup databases. Here is an simple example to show how to backup database by the datetime file name. You can simply modify this to run differential backup or to backup log. Put them as SP in AdminDB and schedule Agent Job for it, just that simple. Use my other script to check review disk space. If you have custom request, please email me.
I suggest readers further enhance this script by coding the parameter in database table such as the backup drive letter, use sys.sysservers to get server name, use a loop to pick up active db names (see my other code publication), use xp_cmdshell to create backup directory, use admindb data table to store runtime and status, etc. I have coded comprehansive DB backup scripts I use for the DBs I manage.
