With ZFS rsync won't really be a good deal, when zfs send/receive does the job 
a wee bit better. Still, has anyone in here tried to use storage with dedup

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er 
et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av 
idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og 
relevante synonymer på norsk.
