Exchange Log File Deletion Question

I have Exchange 2010 running on Windows 2008. Due to backup issues, the log files (on the C: Drive, database on D: drive) have gotten out of hand and are causing the drive to run out of space. I'm running a full Windows backup of the Exchange log file and database folders. I know this will commit the log files and delete them, as I've done it in the past. My question is, once the log files are backed up, even though the database is still backing up, can I move some of those backed up log files off the drive to free up space or do they only get committed as or after the database is backed up? Thanks.

I'm not sure what you mean by  "you don't back up the log files." If you mean, in this particular situation because time is of the essence, then you're probably right. If you mean don't bother backing up the log files ever, I'd disagree because they can be used for disaster recovery. I've confirmed this is best practice from Microsoft.

And I've also confirmed from Microsoft that I need to let the database backup run its course and delete the log files on its own, as you stated. Thanks.
" I'd disagree because they can be used for disaster recovery. I've confirmed this is best practice from Microsoft."

Can you provide evidence of that?

Backups of the log files are not used for DR, other than the logs that I have indicated above, generated between the start and the finish of the backup.
They are completely useless, because after you have run a backup, they are committed and flushed. When you restore the backup they wouldn't be used.
