Backup files

Hi,
I have a scheduled maintenance plan for backing up my database.
I have recently ran out of space and I need to delete some old back up files.

Question:
if I make a backup of a database (full backup) if I want to restore my databse using the transaction logs I can only go back to the latest backup?
If so, why should I keep my old backup files?
Is there any way to tell sql server to overwrite backup files each time it makes a back up and is this a good idea?

thanksWhat I have done here is to have two scheduled maintenance plans for backing up. One that runs every 24 hours that overwrites every time, and a second that appends an incremental every three hours. We then store everything on tape for two weeks.

When you set up the job there is a radio button group to select overwrite or append. If you want to edit your job step change NOINIT to INIT and then the job will overwrite.
