Hi, I'm interested in the overhead of making, cloning, and destroying snapshots. It sounds like the cost for all of these is low, but how low??
For example, could I make snapshots of a system every 5 seconds? every second? More often than that? I'm primarily interested in the time/computation cost of doing these operations, but also about the storage cost. Would it be plausible to do something like take snapshots twice a second on a disk with a low/moderate load? If I only cared about the last 60 seconds worth of snapshots, would that make things much slower since I'd constantly be eliminating old checkpoints? Also, I [i]think[/i] that a while back I saw a technical paper on ZFS's design, but I have not been able to track it down again. Does anyone know if this exists? thanks!
