Recoverpoint synchronous with journal lag?
I have a question, how can you have Recoverpoint synchronous with a journal lag? It doesn't make sense to me.
Am I missing something?
Thanks,
Ed

Hi Ed,
In any replication mode the journal lag is an indication of the distribution performance. So in synchronous mode the I/O ACK is sent by the local RPA or remote RPA depending on whether the replication is local and/or remote and then the I/O is distributed. Where you see journal lag, this is an indication of I/Os not being distributed fully to the journal and replica drives. This is the default mode to ensure that we are not waiting on disk performance as part of the distribution based on what would normally be the slowest component in the replication continuum, i.e. the journal or replica drives.

Thanks Richard, this makes sense now, it's not clear from the Admin guide.
