Exchange log files not being flushed by NT backup

Thank you for helping, here is my situation:
I use NT backup to backup exchange log files and database. Last Friday, the database was unmounted by unknown reason, I manually clear all the logs and remounted the database. But since then NT backup not flushing the log files anymore. I tried restart the server and creat a new NT backup, but still can not flush the log files. Please help. Thank you =)

ESM should have been used to move the logs.

Can you create another backup of just exchange only on ntbackup and give that a shot.  You may have old log files that won't get flushed but the new ones should be taken care of.

Do you see on the database properties the last full backup made? is that backup the last one that you did or it's one old backup? also do you have circular logging enabled?

in the management console, go to organization configuration-> mailbox and click the mailboxstore - choose properties and in the first tab you can see when the last backup was made.

run a new full backup on just the exchange store and see if it purges the log current log files.

It still didn't clear the logs. I run the eseutil /mk and manually delete the logs.
