If by 3-2-1 you mean what I try to repeat to myself calmly when I lose my data, then yes
Data Hoarder
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 (tm) ). Along the way we have sought out like-minded individuals to exchange strategies, war stories, and cautionary tales of failures.
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.
I do not follow it. We have an offline cloud copy and a physical copy at home. We don’t have anywhere to easily store a second copy that’s not at home, and I don’t want to update it yearly. I still suggest the 3 2 1 rule though: i know that if the cloud has an issue or my physical disk corrupts it could be a serious problem.
Op, can you explain me what's this about in short? I'm a noob. :)
I not only follow it, I exceed it for the important things like my tax records, pictures and serial numbers of my valuables, etc.
- Live copy on my Linux box
- Automatic cloud backup onto Google Drive
- Manual sync onto Onedrive via rclone
- Raspberry Pi on my network with external hard drives attached to it, manually updated via rsync
- Hard drives I keep in a safe deposit box at a local bank. These are updated a couple of times a year
- Encrypted archives I keep on my phone and iPad. These are also updated a couple of times a year
Basically, the only way I'm losing all those files is if nuclear war breaks out. If that happens, I'm going to have more pressing issues to worry about than my files being safe.
I use rclone with encryption via cloud and also endpoints backup.
