I really wish there was a viable alternative for physical backups. Blu-ray just doesn't have enough storage space, tape is expensive, and hard drives need to be periodically read.
I've read about holographic WORM media, but I just don't think there's enough consumer demand for the hardware and media to ever be as affordable as blu-ray.
Once upon a time, I could back up all my important data to a stack of DVD-Rs. How am I supposed to back up a 100TB NAS, though? The "best" alternative is to build a second NAS for backup, but that's approaching tape drive levels of cost.
Checkout AWS S3 “Deep Glacier Archive”. It’s perfect for data you only “read” in recovery events, since you have to wait up to 12 hours to retrieve the data. I backup my Plex this way.
I just double my HDDs and put them in RAID1. Not foolproof against data loss, but I wouldn't be heartbroken if I lost my Plex library. For important docs I add a cloud backup.
