Thanks for the reply but is it possible to delete backups without maintenance plans? I am trying to write a script which takes backup of each database and immediately delete it.. The script should delete the old backup of the database immediately after the new backup is taken... For eg:

declare cursor bkup select name from sysdatabases

open bkup

......

...

......

xp_backup_database @dbname .................

delete old backup files

.........

fetch next from bkup

......

Thanks for your help!!!!
