I have a synology NAS where I backup my photos to. What would be the most cost effective way to encrypt and back up this data without having to purchase another NAS and install it at a family member’s house. It would be about 5 TB and would not touch the data unless my NAS completely takes a crap.
Great advice, but you lost me at going to the bank weekly :)
My flavor of crazy is I visit family across the country twice/year and drop off a full backup. A bit hard to recover but, nuke-proof.
