About RAID being a backup?
@jerry So... what's a genuine backup then? I got a RAID 1 thing going, with the most important data mirrored/synchronized on three devices. I hoped it would suffice, but am eager to learn what I could do to make it safer.

@Gilgamesch to be very clear, there is a benefit to raid. Especially with spinning disks, hardware failure is one of the big causes of data loss and raid will help mitigate that. But things like ransomware, fires, accidental deletion, and so on aren’t helped by raid.

I would pair raid with an off-site backup solution using snapshots, with a tool like borg that makes an offsite, encrypted backup that you can restore from in more catastrophic circumstances

@Gilgamesch

unwritable snapshots help with ransomware.
befor you can ask what is a backup you need to define the threat. if you have backups in the datacenter and the center burns with those backups you don't have backup. I can come up with scenereos where all the locations you have backups are destroyed at once.

Raid wich snapshots will cover the majority of your backup needs. It won't cover all but if done well it gets you into that is stastically unlikely for many so maybe you can stop worriying there??? Of course not all data is worth saving in the first place while other is priceless whichiagain points to different backup.

because of the above I conclude anyone saying raid is not a backup doesn't uneerstand the real problem.
