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!
