I have a customer looking for an easy way to determine the day-to-day *block-level* change rate on their open systems hosts. The first thing that came to mind was using OSSV. As part of its day-to-day backups OSSV has to find the changed blocks that need to be backed-up. Is there a way to see how many changed blocks OSSV found (to calculate the change-rate), or the amount of blocks its preparing to send (quantity of changed blocks)? Could the debugging/trace files provide this information? Is there a way to get this information without actually sending the SnapVault over the network?
