I also thought about the 3-2-1 backup rule, but am unsure if that is overkill.
My VM-backups and file-level-backups are proxmox backup server (pbs) backups. Meaning, to have them offsite, I’d need to rent a dedicated root server on which I am able to install pbs to act as an offsite sync-target. With TB of backups, this is gonna get very costly very fast.
I thought about regularly exporting encrypted calendar and contacts onto some free online storage, hoping I can automate this process.
With what I have layed out in my post, to lose contacts and calendar events, both my intel NUC and the zotac mini-PC have to be corrupted at the same time. Or both RAIDs simultaniously failing both drives. Am I not paranoid enough or is that an acceptable level of failure-safety?
Yes, you’re right. As David From Space said in this comment, the real critical data is far less then all of the backed up data.
So I definitely can have an offsite-backup, it just depends on if I can single these things out in nextcloud, possibly via regular export to the filesystem.
Yea if you don’t need much then you can do with exporting not a lot of stuff.
Google is evil but I know that GDrive has pretty low prices on data storage
There are many cold storage services out there with good pricing. If you need a VPS with good storage (to automate sync, etc… idk), I know I would use Interservers, based in the USA, priced at 3$/TB/month (HDD)
But if you only want to sync a small amount then you can do with free services, probably. Don’t forget to encrypt everything when uploading to these services! Don’t want them to be able to see the content of your files.
You’ve got a point, but now I gotta ask: Where do you store your original paperform documents? You know, the real-life critical things. Maybe I’m wrong, but I feel like most people store these things at home, possibly tucked away in a neat, little, sorted folder, for preservation. Which would be a nightmare for all the same reasons, but seems strangely accepted and widely practiced.
No data I own is life-or-death critical. Losing everything would be really bad, but many things can be restored in alternative ways, except the photos.
Also, I may be able to backup the most important stuff (which would only be a few GB at most) to an offsite server, as long as nextcloud (or an alternative) is able to export contacts, calendar and photos, or I can single these out in some other way. As long as this somehow works, I can rent a cheap hetzner server with a few GB of storage and have that be the backup target for the most critical stuff.
What @AtariDump@lemmy.world said is correct, if it’s critical data, 3-2-1 is necessary. I personally use BuyVM as my offsite as it’s got pretty cheap storage (~$5USD/1TB/month), but if you’ve got family or friends with a decent internet connection, it’s trivial to set up a remote sync job to any offsite Proxmox Backup Server, perhaps on a box stored at their house.
Now, just to throw it out there, my actual ‘critical data’ is way smaller than my total backed up data, including my media library, random ISOs, etc. - it can be worthwhile to determine if you really need to backup everything offsite or if you can sort out some less necessary data, and only upload some data to a remote server. Maybe the answer is yes, and you’ll need to account for that!
I took a look at the BuyVM offer you mentioned since it sounds really good, but am I understanding correctly that to make use of the 1TB storage offer I would have to also order a dedicated VM with them to actually make use of it?
(i.e. no mounting from a vps with a different provider)
Now, just to throw it out there, my actual ‘critical data’ is way smaller than my total backed up data
That’s also the case for me. I’d probably count a few GB as critical. Contacts, Calendar, some photos, some documents.
If nextcloud (or some other alternative) has the ability to regularly export these things to an on-disk location, I could definitely backup that to some cheap hetzner server. This will not be a pbs backup, but I can get by with an offsite-backup done by something like restic or rsnapshot
I can ask around for contact info again, same with calendar events I had planned. Some documents can be restored via the original service or by paying a fee to get a new original document, I still have folders full of originals in paper form. Some info can be restored by looking through my bank account or online buying activity. Losing my photos would be really sad, but nothing of that will kill me or destroy my life.
But I definitely can save the most critical stuff (probably a few GB only), if nextcloud (or some alternative) has the ability to regularly export these to an on-disk location. This way, some backup utility like restic or rsnapshot shoud be able to do the job.
Okay so not critical, just mildly inconvenient if lost.
I would just keep one copy in RAID, and for the most important stuff a second copy locally or in the cloud. Yes, RAID is not backup, but a disk failure is probably the most likely failure scenario. Corruption is the second most likely.

The offsite rule is mainly in the scenario where your house burns down for example, or if someone steals your stuff. It can happen.

Maybe you shouldn’t be home hosting important data if you think this is overkill.

My critical documents that MUST be in print are stored in a fireproof safe. If it doesn’t need to be in print it’s scanned, shredded, and backed up.
Photos are scanned and stored. They’re also backed up.

That’s correct, I also pay for their cheapest VPS, which is about $3, pretty good overall for my purposes!

Or a house fire, or flood, or lightning strike, or theft. Or just plain fat fingering something and deleting it all.
If you really mean life-or-death critical, yeah, 3-2-1 is the starting point.
