I have set up a job within MSQL studio to backup all of my databases to a specific file. Then I take that file, compress it, and send it to a backup device. I am currently hoping to make this entire process automated on a weekly basis. However, here is my problem. The job I have created in MSQL Studio currently runs a full backup of the databases, however, it does not overwrite the old data. I have been through the wizard time and time again but can't figure out how to me the process overwrite the old files. The purpose of doing this is to save space on the server.
Can anyone help me figure out how to make the backup job overwrite old files?
