> Myth: ZFS requires tons of memory [...] The only situation in which ZFS requires lots of memory is if you specifically use de-duplication It's also totally worth tons of memory when you use that feature with intent. If you use dedup in combination with automated snapshots you get the most space efficient, fast and reliable incremental backup solution in existence - yes it will consume your whole server, that's the cost (works best separately as a backup server).
