ZOMG!! The SBS 2008 Migration guide tells you to enable circular logging!!!!!! WTF???

It does it for purposes of migration.  When you migrate over the email, those log files will grow.  Now you can leave it disabled and then  just be aware that right after you migrate those mailboxes that store will be a tad large, then it will shrink down and go back to normal size.

What the Microsoft migration docs fail to say is once you enabled it for purposes of migration... go back and TURN IT OFF.

But really it truly is okay to enable it for migration... then to turn it back off afterwards.

Somewhat related question: We're running SBS2008, and have the SBS backup and circular logging both turned off. We're trying to use Barracuda's backup agent to backup Exchange.

Unfortunately, it's doing a full backup every single day because the agent thinks circular logging is enabled. Running the agent at different time of the day, it seems that something is enabling/disabling circular logging at some point.

I've been working with them for weeks on this, and it doesn't seem to be anything on their end.

Is there anyway to determine what might be causing this? Perhaps a way to bump up logging and review when/if circular logging is being enabled/disabled?

Thanks for any help!

You should only turn Circular Logging off once you have a working local backup that trims the logfiles.

If you virtualise SBS and back up underneath it, then you'll want to leave circular logging on if you want to save the administrative overhead of having to manually handle the logfiles.

@JeffreyTarnoff - you probably want to run ProcMon and capture a log to help the Baracudda techs work out why the agent thinks circular logging is on. It's possible it's querying a part of the registry that differs between an SBS 2008 box and a Win2008 box running Exchange 2007.

What's wrong with circular logging?  It has it's place to save admin overhead if you are not using GRT based backups.

The SBS backup is an image based backup is it not?  They always assume that the user would be using that.
