How do you back up your Mac? Ron McElfresh has some experience doing just that and keeps it simple.
That means each Mac has at least one cloned disk which can be used in an emergency situation, and at least one disk with mirrored critical files (Movies, Music, Documents, etc.). All those files are stored locally using the NewerTech disk docks. No RAID array. No NAS.
What? That’s IT sacrilege, right?
Why not follow the NAS trend? Or, invest in RAID arrays? Or, just use Time Machine? NAS and RAIDs can get expensive and have maintenance issues; both with set up and ongoing management. Time Machine is good for finding misplaced files, but is a horrid restore system (cloned Mac disks are faster and more accurate). For me, the KISS method rules.
