I like to add “0”… which somehow relates to not having untested restore systems.
I have a different strategy, it’s called 3210:
3 TB of data at stake
split between 2 drives
only 1 copy
0 shids given
For anyone who needs to hear this: RAID is not a backup. RAID is not a backup.
But putting 2 copies of my files in OneDrive is 3-2-1, right?
But it’s all stripey! the data is redundant!
Among my top 3 repeated lines at work lol
If you get raided and have no backup afterwards, then it wasnt a good backup. So yes RAID is not a backup.
who can afford that though?
It’s not all that expensive. The cost of storage is constantly decreasing over time. You can get a safe deposit box for something like $10/year if you also want the added benefit of an offline copy. I haven’t looked at cloud storage pricing, so I dunno what that runs.
Just realised my primary, backup and offsites are all spinning platter disks. When they say two types of storage, what does that mean exactly?
Differing kinda of storage in case one doesn’t work with the device being restored to, or something happens that’s more likely to affect one type of media than the other. A strong electrical field could scramble the hell out of spinning rust’s magnetic media, while doing nothing to optical media, for example.
Finding a good place for the offsite copy and keeping it reasonably fresh can be pretty hard.
It’s why the paid services are successful. Another option I heard about is to have a “data buddy” so you both install a NAS at each other’s house, sort out access etc and that’s your off-site.
Yeah. My solution is raspberry pi w/WireGuard + HDD at inlaws. Initial backup was done locally, nightly backups rsync’d over (I don’t generate a ton of data, so it’s mostly just photos from my phone).
Unfortunately, I don’t have that kind of internet speed …
We “only” have ~35Mbps upload, but that’s plenty since the initial backup was the only large transfer. Daily backup transfers are generally pretty small for me.
But getting the initial transfer done locally was definitely important for my use case!
I have ~4 mpbs upload ;-;
You probably don’t generate more than 4 megabits of backup-worthy data on average every second
Exactly — this is ~10GB every 6 hours (which is probably a reasonable amount of time to run a backup while not interfering with active Internet use).
Basically the only backup-worthy content I generate is casual photos and videos, and these are nowhere near that size (Immich database backups also take up a bit but I could certainly be smarter about how I handle these backups).
I have three copies, one on my nvme SSD one on my sata SSD and one in my OneDrive account which I can only assume is HDDs on the other end so I’m probably doing it right.
Make sure oneoff the copies is airgapped or append-only so that if a ransomware overwrites your copies you will still have the original.
For home use it’s decent enough to have 2 copies, and 1 off-site.
Especially if 1 of your copies has some kind of redundancy, like RAID 1.
I’ve got 3 local copies. What are you gonna do about it?
Fr tho, main pc, NAS and laptop. Trying to help friend build a NAS and then swap offsite backup space.
