How to clear up space for Exchange 2007?

I have an SBS 2008 server that keeps running out of hard drive space.  I want to know how I can clean it up so that it a) doesn't run out of space so quick and b) if it does run out of space it re-writes over the old logs instead of just stop working.

Backup Exec 12.5 is on here, hasn't been run in god knows how long.  I'm running the Exchange portion now in hopes that it'll clear up the log files automatically.  Anyone have any other suggestions?

The end result is going to be bad in such a case.

The backup has to be running regularly. You may try some tricks like circular logging but do this at your own risk.

Drives will fail or data will get lost sooner or later and if you are the admin then it will be blamed on you.

The backup needs to be fixed. If you haven't already, ensure that Backup Exec is fully up to date using Live Update within the application.
I don't think I would use circular logging, but you can compress the log files to get you space back. DO NOT compress the entire directory, only compress the oldest log files. Then fiox the backup so they get flushed correctly.

I would also check the IIS logs location - those can build very quickly and chew a lot of space. IIS logs are not flushed automatically unless you set it to do so, and can be deleted without harm to the system.
