Greetings, mixture!
For completeness having tried to keep my post simple.
Primary backup to Brand X RAID1 NAS that physically lives in a different building and is well hidden for good measure
Secondary backup to the USB HDD (now smartphone)
Tertiary backup to Brand Y RAID1 NAS that gets swapped for its sister (or brother, if you like) each time I go to the office (about once a month)
All encrypted.
The common weakpoint with the NAS devices is of course the disk controller on each, but this aside, I have five up to date copies of every file and seven copies if we are prepared to be up to a few weeks out of date.
Fine by me!
