Thanks for the response. I appologize. I should have been more clear.

I'm doing snapshots of iSCSI LUNs for VMWare. I have figured out how to create a snapshot and schedule the one snapshot. I have also figured out how to make the snapshotted LUN available in VMWare to mount and restore individual files from it. This part is excellent.

What I need to know is if it is possible *using the same snapshot volume* to create multiple snapshots back in time on a hourly, daily, weekly basis. Or do I need to create a snapshot volume for each snapshot I would like to take?

Is there a good way to estimate how much data will change when considering how big to make the snapshot volumes?

It seems that the open-e snapshot system is not designed for long term snapshots (ie keeping a yearly snapshot) but is more for temporary moments in time. Is that assumption correct?

Thanks again,
Ryan
