I’ve always heard that you folks like to keep tons of backups of your stuff. I have also heard that there is this 3-2-1 rule about keeping you backups. My question is: do you follow it personally or is it something that people just tell you to follow?
I use rclone with encryption via cloud and also endpoints backup.
what’s the 3-2-1 rule?
This article explains it.
well I have encrypted off site copies at my partners house in London and my other partners parents house across the state. just be poly!
as far as the two goes, I have copies on physical spinning platters and copies of critical data on ssds.
as far as the one is concerned, I have separation of copies from the Washington coast to London so it would have to be a world ending disaster to cause me to lose all copies of my data.
that being said it has taken me the better part of a decade to get this far and they are all cold copies so they require maintenance to keep up to date. that being said they can’t be infected from the internet very easily that way
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 siteMy 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)
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.
What do you use for encrypted containers? Veracrypt?
You may laugh but I burned all my super important stuff(hi res scans of photos going back to wheN they got off boat and lot S of other pics and vid’s ) onto 50 Blu-ray disks. Since I have no friends I’d trust I found a piece of 6 inch pvc pipe glued cap on one end and threaded plug on other leak checked it put disks in it and buried in the yard a foot and half deep with p gravel around it. My main worry is Forrest fire I live in woods. Only thing in my backyard is me and the deer and a big ass raccoon. It doesn’t need updating. It’s been underground 5 yrs now I should dig it up and have a look I suppose. My daughter that lives a few hundred miles away knows where it is incase I get ate by raccoons. But not what’s inside of it. She has the originals. So not a good place for digital copies. There’s also a note in my will for someone to go dig it up. It’s not hard to find has a paver stone as x marks spot.
Have you considered encrypting the data and storing it with a cloud provider?
No I don’t want to have a forever reoccurring bill. And who knows ten years from now the encryption method we use now can be cracked by some method we don’t know of now. Or the password is lost to time. And I dont trust the cloud much I use it for some stuff but not the Crown Jewels. My biggest fear is that I die they sell house new owner finds it that’s why I have it in my will to dig up before house is sold. But I’ll be dead and won’t care also. But they don’t need to see a video of my daughter when she’s two months old pooping on me.
you definitely sound like someone who lives in the woods
So it’s 6 inch PVC… how long is it? We need to know it’s capacity in TB.
This seems fairly sensible to be honest
It’s not.
Why not?
Are you really asking why it’s not a good idea to go dig a hole in some random corner of the forest and store your “sealed with glue” PVC pipe full of really important media on DVDs to save for your daughter (who, coincidentally, also has the originals already?) for long term safe data storage?
Or do you just wanna chat?
I mean, I’m cool w/ the second one but I have a hard time taking anyone seriously for the first one.
Optical disks buried in a back yard… do you check them for disk rot? If you aren’t testing the restore, you don’t have a backup!
I have 3:2:1 for my crucial data ( pictures of family and travels and digital documents like tax returns). Basically one main copy another copy on an old nas with shucked drives not connected to the internet and one cloud copy. It is worth it because I would hate hate to lose that data.
I have 2:1 for my media. Just a local copy . If the apartment goes up in flames or a freak lightning burns it down I will have to re-download it again or I will live without it and ghats fine. For a long time the media had no backup but just raid and snapshots to protect against hard-drive failures and dumb user errors.
It’s all about your means and risk appetite.
The 2 in this rule isn’t clear: 2 different media?
Why is it important if it’s DVD & HDD or SSD & HDD?
For home use, it’s just two different devices that can be the same type, like harddrives in two servers, but not redundant data storage in one device, like RAID or just having two copies of files on the same drive. For corporate, most will probably interpret it as two different media types, like harddrive and tape. You want them seperate to prevent accidental deletion of files, ransomware and such.
Diversity in Failure Modes: Different storage media have different failure modes and life expectancies. For example, a hard disk drive (HDD) might be susceptible to mechanical failure, while a solid-state drive (SSD) might have limitations in terms of write cycles. By diversifying the media types, you reduce the risk that a single failure mode (like a power surge, mechanical wear, or temperature sensitivity) could compromise all of your backups.
Reducing Common Points of Failure: If all copies of your data are stored on the same type of device, they may all be vulnerable to the same type of failure. For example, if you have all your backups on different HDDs from the same manufacturer and there’s a manufacturing defect, all your backups could fail simultaneously.
Technology and Ageing: Different technologies age and become obsolete at different rates. By using multiple types of media, you’re less likely to find yourself in a situation where all your backups are stored on outdated or unsupported technology.
Physical and Environmental Threats: Different types of media have varying levels of resilience to physical and environmental threats like fire, water damage, magnetic interference, etc. By diversifying, you increase the chances that at least one of your backup mediums will survive a catastrophic event.
Data Recovery Options: In the event of a failure, different types of media may offer different data recovery options. Some media might be easier or more cost-effective to recover data from than others.
CSVs ftw
I don’t have too much critical data to backup. I have a low power thin client (lenovo m720q with a 2tb sata drive) I park at a friends house on their network. In exchange I let them borrow a bit of space on it too.
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,
I follow it for the most critical data, other data get just one copy (but those data is not important to me)
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.
