Who are we?
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). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
We are one. We are legion. And we're trying really hard not to forget.

I live dangerously. Ive no backups.
I tip my fedora at you sir
Synology NAS
Edit: plus two SSD backups. I need to re-engage Backblaze for offsite.
4 bay nas 22tb drives = 88tb as a single volume. Backed up to offline single storage drives that are timestamped. Anything newer than that timestamp gets rsynced/robocopied to a new drive until it's full., update timestamp, swap drive and rinse repeat. If a drive fails, just replace it and copy the contents of the backup drives to master and restored. Alternatively you can set a single disk tolerance raid.
Unraid checking in. 150TB ish. Dual parity for media files on XFS drives. Can lose 2 drives before array data is at risk, and even then if a drive fails, I’d only lose the data on that drive not the entire array.
Important data is on ab encrypted ZFS array which is snapshotted and replicated hourly to a separate backup server and replicated one more time weekly to 3.5” archive drives which are swapped out to a safe deposit box every few months.
I used to use rsync to do it but snapshot replication with sanoid/syncoid does the same thing in a tiny fraction of the time by just sending snapshot deltas rather than having to compare each file.
Used to use rclone encrypted to gsuite, until that gravy train ran out lol.
Now I've got 3 Unraid boxes (2 on site, 3rd off) and a metric shitton of drives I've accumulated over the years.
an unholy ensemble of 4 external drives and 2 cloud storage providers managed with git annex
capacity: 3 TB + "pay as you go"
available: 1TB
used: 1.01TB
the drives were originally 5, then 1 failed and added the "pay as you go" s3 provider to pick up the slack
git annex handles redundancy and versioning, i configured it to keep 2 copies of every file across the 4 drives and the s3 provider, then i got 1tb of free onedrive space from my university and i'm in the process of making a full backup of everything in there
not really backup as much as redundant storage, but i think it's close enough
if anyone wants to roast my setup please do
