Add-MailboxDatabase within an Exchange 2010 SP1 DAG Manually across a WAN

Hi,

I have three members in a DAG two at one site (Site A) and one at another site (Site B).  The server in Site B only runs passive copies of two databases as it is connected over a WAN (20MB link) and is designed as a DR site.

The two databases on the mailbox server in Site B went stale last week and I had do delete the databases and then re-create them.

The databases are about 135gb each. and even though the links are 20MB it is still taking about 50 hours to do the database copies and fail in the middle if the link goes too slow or other such issues happen.

I have traced the data across the link and it is using MAPI and it is doing large amounts of chatter and that would explain why the transfer is so slow.

I have a few questions and am looking for suggestions on how to get these databases’ replicated so they can act as passive replicas as they have done for months now.

1. Does anyone know how to force it to do less chatter and fully use the capabilities of the link to do the transfer.

2.  Can the transfer be done manually, so I can copy the MDB file onto a removable device from a replica (without dismounting the mounted database) copy the mdb file to the server at Site B from Site A and then get it to update itself to what is current without trying to seed everything over the WAN hence getting it running faster than its seeding live process.

Thanks Peter
