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)?&nbsp;&nbsp; Could the debugging/trace files provide this information?&nbsp;&nbsp; Is there a way to get this information without actually sending the SnapVault over the network?</P></BODY></HTML> Thu, 05 Jun 2025 07:03:22 GMT https://community.netapp.com/t5/ONTAP-Discussions/Using-OSSV-to-determine-a-host-s-change-rate-or-quantity-of-blocks-changed/m-p/74933#M17496 reide 2025-06-05T07:03:22Z Re: Using OSSV to determine a host's change rate or quantity of blocks changed? https://community.netapp.com/t5/ONTAP-Discussions/Using-OSSV-to-determine-a-host-s-change-rate-or-quantity-of-blocks-changed/m-p/74938#M17497 <HTML><HEAD></HEAD><BODY><P>If it's a Windows host you can download the OSSV Profiler from the Field Portal and use it to determine the change rate.</P><P>Thanks,</P><P>Chris</P></BODY></HTML> Tue, 14 Dec 2010 15:36:48 GMT https://community.netapp.com/t5/ONTAP-Discussions/Using-OSSV-to-determine-a-host-s-change-rate-or-quantity-of-blocks-changed/m-p/74938#M17497 bwood 2010-12-14T15:36:48Z Re: Using OSSV to determine a host's change rate or quantity of blocks changed? https://community.netapp.com/t5/ONTAP-Discussions/Using-OSSV-to-determine-a-host-s-change-rate-or-quantity-of-blocks-changed/m-p/74944#M17498 <HTML><HEAD></HEAD><BODY><P>Hijacking an old thread here....
