I'm using snapper for automatic timeline snapshots of my filesystem.  The issue I have is that it continues to take hourly snapshots even when nothing on the filesystem has changed, which causes the disks to spin up once per hour.  Ideally I want them to stay spun down if nothing is changing.Does anyone know if I can:Configure snapper to only take a snapshot if something has changed since the last snapshot?OrReduce the cadence of the regular timeline snapshots from something less frequent than hourly?
Snapper to only take snapshots if something has changed, or at a lower cadence
