Data Hoarder

We are digital librarians. Among us are represented the various reasons to keep data -- legal requirements, competitive requirements, uncertainty of permanence of cloud services, distaste for transmitting your data externally (e.g. government or corporate espionage), cultural and familial archivists, internet collapse preppers, and people who do it themselves so they're sure it's done right. Everyone has their reasons for curating the data they have decided to keep (either forever or For A Damn Long Time (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.

I've always heard that you folks like to keep tons of backups of your stuff. I have also heard that there is this 3-2-1 rule about keeping you backups. My question is: do you follow it personally or is it something that people just tell you to follow?

yes, i am over 100TB and backup everything on two sets of external disk arrays. one is at my house only powered when i perform my monthly backup and the other is at the in-laws house. i swap the two sets every 3 months

here are the enclosures i use

https://www.amazon.com/gp/product/B07MD2LNYX. between all my backups i have 4x of these enclosures and 32x drives

backup 1

--> 8 bay USB disk enclosure #1: filled with various old disks i had that are between 4TB and 10TB each. the total USABLE space is 71TB

--> 8 bay USB disk enclosure #2: filled with various old disks i had that are between 4TB and 10TB each. the total USABLE space is 68TB

Backup 2

Exact duplicate of backup #1.

i have windows stable bit drive pool to pool all of the drives in each enclosure. i also use bitlocker to encrypt the disks when not in use.
