Remove inactive entries from transaction log!

[ndba]

Hi!
I have a sql server 2000 SP 1 and when I go to back up a database (full backup, overwrite) using enterprise manager, the [Remove inactive entries from transaction log] option is grayed out. The database is set on Full recovery. I would liek to know why this option is grayed out ? Is this a bug ?
Any help will be appreciated.

Thanks

I think it's only for backup transaction log, not for backup database.

Full backup does not truncate the transaction log, that's why it's grayed out.

Hi!
The same option is enabled on my sql server 2000 SP 3 when I try to perform full backup. Why is that ?

Beats me, I see options enabled when trying to backup Pubs database which is in Simple recovery model.
