Hi, currently I have a almost none backups and I want to change them. I have a PC with Nextcloud on 500gb ssd that I also use for gaming (1tb system drive). Nextcloud would be used to store/sync images, documents, contacts, and calendar from my phone and laptop. I also have an old pc that has 2x 80gb, 120gb, 320gb, and 500gb hdd. I want to use it for other backups like OS snapshots, programming projects, etc. but its not a big hdd but a lot of small hdds. Should I store each backup on 2 drives? Can I automate this? Any suggestions would be helpful.
If I’ve learned something about selfhosting and backups it is that you can trust HDDs to spin for 3-5 years and should still do backups. I myself do backups to HDDs that are only powered on for these backups. I’m still not sure if thats enougth.
Raid is more for an always-on solution, but not great for safe backups. They still might get damaged at the same time, because you bought them at the same time, from the same vendor and they have the same usage time.
