For everything that is personal, such as photos, videos, file backups, etc, I follow 3-2-1.

I have a raid1 array with all my files, and any new files are pushed to aws S3 in a weekly basis. its weekly as i may have plenty of GB of photos and videos after a big trip and with my current internet speed 24 hrs may not be enough to upload everything :/

For cold storage stuff, aka everything until last year I also copy it at an old nas at my parents house that is only connected to power and network when i need to add the backups and 2-3 times per year otherwise.

It’s also good to keep a raid aray protected with a surge protector and UPS.

OK who rubbed the lamp? Of course I follow the rule religiously!

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

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,

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.

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

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.

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.

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.

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.

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

For me I used the cloud as my offsite backup but it’s only the most important stuff and it’s scattered between several Gmail accounts iCloud and OneDrive. Working on consolidation but right now it’s backed up somewhere other than my server. Back when I first started my data hoarding journey I only had a single harddrive and my old computer. Important stuff was already saved to the cloud so all I did was download it onto the drive. I still primarily save anything important in the cloud first but it’s all synced with my server too.

Op, can you explain me what’s this about in short? I’m a noob. :)
