Overwriting backups

I'm backing up my transaction log on backup device every 15 minutes. I want
every backup expire in 1 hour so only 4 sequential transaction log backups
reside on my backup device. How do I do that? Thank you in advance
Leon
You can't if you are using a single device. It is all or nothing with your
only options being to use INIT or NOINIT. INIT will remove ALL files in the
device and NOINIT will simply append. Don't use a logical device and
instead backup to a different file name each time. Then you can delete what
you want.

Overwriting Backup Set

Hi,
I did a full backup of my database, but everyday when it is backing up I
would like it to overwrite the previous day's backup.
I'm doing it thru Transact-SQL script(T-SQL) so i am entering the following
command:
"EXEC sp_addumpdevice 'disk', 'backup_file6', 'C:\test' backup database
WSS_Content to backup_file6 with init"
Is this right? Or do I need to include something else?From BOL:
INIT Specifies that all backup sets should be overwritten, but preserves
the media header. If INIT is specified, any existing backup set on that
device is overwritten, if conditions permit. By default, BACKUP checks for
the following conditions and does not overwrite the backup media if either
condition exists:
a.. Any backup set has not yet expired. For more information, see the
EXPIREDATE and RETAINDAYS options.
b.. The backup set name given in the BACKUP statement, if provided, does
not match the name on the backup media. For more information, see the NAME
option, earlier in this section.
To override these checks, use the SKIP option.

Where do I need to go to see the EXPIREDATE and RETAINDAYS options?
Also, I use the SKIP option with "with skip, init"?

I'm trying to do an automated backup where it overwrites the previous
backup. I'm running the command:
"EXEC sp_addumpdevice 'disk', 'backup_file9', 'C:\Friday' backup database
WSS_Content to backup_file9
with skip, init"
But when I go to View Job History, I'm getting the error:
"The add device request was denied. A physical device named 'C:\Friday'
already exists. Only one backup device may refer to any physical device
name.[SQLSTATE 42000](Error 15061). The step failed."
Why exactly is that? What needs to be done?
Please help.......

need to do this once.

What command exactly do I need to use -
"EXEC backup database WSS_Content to backup_file9
with skip, init" ?

BACKUP DATABASE mydb TO backup_file9 WITH INIT
This command will backup "mydb" database to "bacup_file9" dumbdevice and
it'll overwrite the old one(s).
