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.
