Hi Folks,

What are the side effects when enabling the circular logging during the mailbox database failover to the secondary node ?

is there any side effects when the database is seeding ?

The reason it is turned on is because there is not enough disk space to hold the 20 storage groups in the hard disk drive.

Hi,

As per

Exchange 2007 – Using VSS to perform an online offline database seed.
http://blogs.technet.com/b/timmcmic/archive/2010/05/25/exchange-2007-using-vss-to-perform-an-online-offline-database-seed.aspx

"In CCR this is handled for you automatically every time you create a database." so that means that in case of CCR there will be no dataloss.

Hope that helps :)

So in the event of offline seeding, do I need to copy the log files as well to the other node (from the source both Databse.EDB and Log files) as well ?
