Does the conventional 3-2-1 strategy works here for large capacity drives? A large capacity drive is considered as 8TB and above based on the info on the net.
I have 6x20TB HDDs in a NAS array
So to execute having 3 copies of back up data means I need another 3x NAS arrays for storage, right?
Can forget backing up to cloud or SSD since storage is large.
Using my country's currency for calculation 1x Seagate IronWolf Pro 20TB costs $500. So 6 drives would cost $3000. Need to factor in the NAS too.
For 3 copies of backup data would mean $9000 for drives + 3x backup NAS.
Overall costs would be the primary NAS array + 3x backup NAS arrays = 4x NAS arrays
I can say for smaller capacity drives like those 1 or 2 TB this 3-2-1 strategy works well even for SSDs.
But in my case is it practical for a home user using the 3-2-1 strategy?
If not, then would just a backup NAS array be suffice?
