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 backups

Hi Leon,
If you are using DB Maintenance plan, in the transaction log backup section,
"Remove file older than" provides the functionality you are looking for.
And if you are using, T-SQL you can specify "RETAINDAYS" parameter.
Check out for BACKUP in BOL.
Thanks

LeonYou 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 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
LeonHi Leon,
If you are using DB Maintenance plan, in the transaction log backup section,
"Remove file older than" provides the functionality you are looking for.
And if you are using, T-SQL you can specify "RETAINDAYS" parameter.
Check out for BACKUP in BOL.
Thanks

The key-word here is BACKUP DEVICE, Maintenance Plan does not have option to
backup to a DEVICE.

overwrite backup don't overwrite the backup device
I created a plan for a backup. This first truncates the log and after backups the data with overwrite mode and after backups the transaction log with overwrite mode.
The process is using different backup devices for the data and log backups.
The first 2 step is success (truncate and data backup) but in the last step the backup process don't overwrite the backup device. Why ?It had been set to Full databases, after i set to specified database...it was success.
So if I'm setting to full databases, it's can't overwrite the log backup device (only append)...
sneaky
|||
after when i set to specified database and i choose the db in the script was "backup log db_log INIT" so it didn't have inconsistency between the form and the ran sql script.
(sorry my english)|||

|||Hi Molnarcs,
Just FYI
The backup device can be overwritten even when doing the log backups.
Jag
|||when the backup was set to full databases then in the form the mode was overwrite but if i checked the sql statement (plan's history log- view T-SQL)...in the script was the "backup log model... NOINIT...backup log db_log....NOINIT"...after when i set to specified database and i choose the db in the script was "backup log db_log INIT" so it didn't have inconsistency between the form and the ran sql script.

Hi Molnarcs,
you r right you have to secify INIT option with backup log.
