The article refers to a problem specifically with NTBackup. You can have 
the Exchange database and the OS on the same partition, but you cannot 
back both up in the same job. I am not familiar enough with backing up 
Exchange in bacula; it may use similar underlying code, and thus have a 
similar problems.

With NTBackup you have to back up just the SystemState, and then back up 
the Exchange database separately.

Not really. All circular logging means is that the old database log 
files will be deleted before the next backup. In normal operation, these 
old log files are never used anyway.

The only reason somebody might want to keep them is to allow restoring 
the Exchange database to one particular point in time. Instead of the 
traditional "restore the last full backup, and then restore the 
incrementals" you would restore the full backup plus all the log files 
since then. Then you replay the log files until the exact point in time 
you want.

In practical terms, most people never needed this capability, so 
circular logging actually is perfectly fine.

In Exchange 2010, circular logging is the default.
