I use rclone with encryption via cloud and also endpoints backup.

In my case most of the backups are done to local drive and to Acronis Cloud, some of these backups tasks are also going to external drive and FreeNAS share. Lastly, quarterly backups are going to Glacier Deep Archive in encrypted containers.

Yes, I follow the 3-2-1 backup rule
1st copy is my working data
2nd copy is to an external HDD
3rd copy is offsite to a cloud site

My backup copies are incremental, using a backup service (Arq)

I also have device backup, with my data auto-sync’d between devices (Mac and iPad)

My music, photos, and documents are backed up remotely (Dropbox).

Everything else is just backed up to another machine.

For me it’s cost. 80tb wouldn’t be cheap enough for me.

I get down on my knees every month just to pray that I don’t need to use my back ups. Then, when the inevitable happens, I get down on my knees and pray thanks that I have my back ups.

More religious than anything else in my life. I have had numerous events occur over the past 2 decades and can confirm that restoring is so much easier and better than installing from scratch. Also data( in my case the usual pictures/movies/documents/etc) are at least duplicated on other media/devices/etc.

I follow it for the most critical data, other data get just one copy (but those data is not important to me)

3-2-1 is the minimum I follow for anything important.

1 copy is the working data, 1 copy is a full system image stored on a NAS with incremental backups done nightly with Veeam, and 1 copy is on Backblaze B2 with incremental backups done nightly with Restic,

I’m a photographer with almost 25TB of photographs.

Primary storage: diy truenas On-site backup: off the shelf branded nas Off-site backup: cloud storage.

Just a note: any automated backup you need to be 100% sure you have set it up to not sync deletions.

I follow it personally, backup locally to a WD drive, and cloud is idrive

Not yet. My 2nd form of media will be Blu-ray 100GB Discs, and second location will probably be another house 30 minutes away. I DO have about 3-4 copies of my most important data.

Locally, I have RAID on my NAS, my sentimental stuff is mostly synced with other systems through seafile (similar to nextcloud), and is also backed up to backblaze.

For everything else, it’s just RAID.

I do main data at home, external HD as backup offsite (I update maybe 1-2x a year otherwise it’s turned off/unplugged), and any new files not on the backup are in cloud storage + local HD, separate from main data.

If either drive failed I’d just order a new one since the odds of both failing within a couple days would be low.

There are excellent articles that go over all this. Do a something search.

Bottom line, yes, you should at least do 3-2-1 methodology. More than that is gravy.

I have a 2-2-0 for now. The problem is with 100 TB of data, it’s hard to find an offsite back up that is reasonable priced.
Everyone else seems to have parents or these things called “friends” that they can ask to hold onto. Wonder where I can find them.

If by 3-2-1 you mean what I try to repeat to myself calmly when I lose my data, then yes
