I have an exchange 2007 server that's running out of space, the log files are on a NAS (M drive), however they are not purging. The backup is running on the C & D (Exchange databases are on D). Should the log files be purged with the backups even though they're not on a backed up drive (the exchange databases are on the drive). We are using Windows Server Backup (Server 2008).
If I turn on Circular logging, what will happen with the current log files?
