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 have a different strategy, it’s called 3210:
3 TB of data at stake
split between 2 drives
only 1 copy
0 shids given
who can afford that though?
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!
If you get raided and have no backup afterwards, then it wasnt a good backup. So yes RAID is not a backup.
Among my top 3 repeated lines at work lol
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
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.
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.
I just keep one copy on my main PC and a backup on my Nextcloud (which is also at home) and occasionally I may download a copy to my phone
