Hi there, When the link is down, transfer is paused and production copy enters marking mode. In this mode, all changes are marked in a bitmap stored on the production journal. Since, this is a bitmap, capacity cannot ran out - changed data are just marked as being changed rather than being saved on the journal.  Hope that helps, Idan
Folks,   Is there a way to determine how much journal log space is being used locally when a link to the DR site is down?  Normally when the link is up, you would click on the DR site policy and it will give you the protection window. So i had assumed that when the link is down, you would click on the production policy to give you the same info. However it is blank.  We are currently running RP 4.0.2  Thanks
