Circular Log question.

We enable circular logging in Exchange 2010 to conserve storage space.  

Do we need to specify size of the log or Exchange will do it automatically?

When it comes to restore, if circular logging is enable, does it mean that I can only recover the database up to the the point when the last full backup was made and whatever "differential" in the circular log?

Please advise.  

Thanks.

Hi,

when you enable circular logging it will automatically delete logs, so you cannot specify size or anything else.
Since you wont have logs, then you can restore DB only to the point when Full DB backup was done.
Of course, you may be able to repair database, and bring it up to the latest point.

Circular logging is not recommended in production, specially in some long interval.
Maybe just as a quick fix, when you are out of free space, but not something that should be done regular.

Do you use windows backup or have some 3rd party?

Regards,
Ivan.
