Exchange 2007 SCR questions

Regarding Exchange 2007 SP2.

Have been reading a great article about SCR here: http://blog.chrislehr.com/2009/10/exchange-2007-scr-how-to-part-1.htm. I was hoping someone could confirm my understanding.

1. The ReplyQueueLength is on the Target will always be high unless a backup is taken of the relevant database.

2. CopyQueueLength is number of logs on the Source waiting to be sent to the Target. A high number means that these logs can't be sent and there is some sort of problem.

3. It is possible to Suspend SCR for a SG (suspend-storagegroupcopy) - but how I can tell if SCR is suspended for an SG? I know I can run get-storagegroupcopystatus - if the status is SUSPENDED, does this mean that the copy has been suspended manually by an Admin? There is no other way? Is there any other way a SG Copy could fall into that state?

4. If I have a standby server (i.e. SCR target), is there anyway to find out what the associated Source is? I know I can run get-storagegroup xx | fl to find out a source's target, but is there any way to do this the other way around?

5. And one more non-SCR related query. If I jump onto any Exchange server, is there a way to find out what its role is (e.g. SCR target, Hub, CAS etc)?

No, ReplayQueueLength should not be high the backup will flush the logs however Logs should be replayed (unless you sepcify a lag time)

2. CopyQueueLength is number of logs on the Source waiting to be sent to the Target. A high number means that these logs can't be sent and there is some sort of problem.

True

3. It is possible to Suspend SCR for a SG (suspend-storagegroupcopy) - but how I can tell if SCR is suspended for an SG? I know I can run get-storagegroupcopystatus - if the status is SUSPENDED, does this mean that the copy has been suspended manually by an Admin? There is no other way?

It can be suspended automatically in case of a problem or by an admin

4. If I have a standby server (i.e. SCR target), is there anyway to find out what the associated Source is? I know I can run get-storagegroup xx | fl to find out a source's target, but is there any way to do this the other way around?
nop this is the way to do it

5. And one more non-SCR related query. If I jump onto any Exchange server, is there a way to find out what its role is (e.g. SCR target, Hub, CAS etc)?
yep you can open the EMC -> Server config you will see a list of the servers with their roles
