Exchange 2003 / 2007 Logs and Script

Is there a script I can use that will tell Exchange that the database has been backed up, and that it should commit and truncate the logs.

I know this happens automatically when you use Backup Software (Like Backup Exec with the Exchange Agent enabled), but we are testing some replication software for a project.  After the software replicates the Exchange Databases, we want to call a script that basically says the DB's are backed up and you can commit and truncate the logs now.

Thanks in advance,

Chris

you could have this put into csv format using
get-mailboxdatabase | select name,*back* | export-csv c:\db-backups.csv

I'm sorry, I don't understand your comment.

We don't have an issue backing up the DB, the problem is that if you don't call some type of "Script" "Agent" etc... the log files will continue to pile up eventually consuming all your disk space unless they are committed and then truncated.

If you have a script that does that, it would be ideal.

Thank you for your attention and quick response.

i thought you were asking for a script to determine the backup of a database

the only way to truncate the logs for an exchnage database is to perform a backup (full and then incrementals will) or enable circular logging (not recommended)

When you say a "FULL BACKUP" what do you mean?  Please be as specific as possible on this.


How does Exchange "Know" you have actually done a FULL BACKUP?  Again, more detail on this is better if you have it.

Thanks again for your attention to this.
