Gathers statistics or something like that. 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! D.=
