not sure if I should put them all in this mail? -- I've put them here:

There's only a handful of datasets (three on one machine, six on the other), and currently no snapshots. No deduplication.
Some datasets on one machine have compression, the other machine doesn't have compression turned on for any dataset.

No minutely cronjobs, automated logons, nothing alike.

Thanks!
