Hi, I thought I would bring this topic in a separate thread so that it can be discussed independently. As users start taking a bunch of snapshots and keep them as backups, we see the following use pattern when the snapshots get recycled. Different snapshots have different life cycle. When some one decides to keep 'x' snapshots, at the recycle phase, the least recent does not necessarily get deleted. As users want to keep the daily snapshots for a much longer period than the bi-hourly snapshots. In the same way, weekly snapshots live longer than daily snapshots. I think this is pretty much similar to the way the current backup tapes are managed. I want to know if this is the kind of use case that users are having or the developers are thinking. The reason why I am posting this is that this out of snapshot deletion scenario, poses some interesting challenges in the design on the solution of multiple snapshots that share blocks with each other, as it is a lot easier to design a solution where the least recent gets deleted always.
