Hello Dharmesh,
Just to make things clear, there are 2 type of logs in VVR, SRL log & DCM log...
If you have enabled DCM protection, once SRL log is filled, VVR will start logging to DCM...
If I understand your query, if replication is paused or rlinks disconnected, whatever new writes are coming down will be logged to SRL, thats how VVR functions to keep the track of writes to replicate to secondary, so if you want that your SRL log should fill mimimum, well that depends how much your application is trying to write... control your application writes & log filling will be controlled...
Don't think there would be a way to restrict this....
Hope this helps..
