3-2-1 strategy with HDDs only? (alien.top)
 

Hello,

​

my total dataset is now 2TB and it grows about 1TB/year.

Is this a sound backup strategy:

- buy 3 hdds today, rotate backups between them, so I have at least 2 previous versions of a file

- replace them every X years, say every 3 years, so the chances of catastrophically losing all data are very very low

I have been looking at tapes also but the drives are quite expensive, and my dataset size probably does not justify them - or does it?

​

I'm having trouble finding the blue where I live, so I think I'll go with the Red Plus 8TB, WD80EFZZ...is it helium or air?

Thanks. How about the corruption issue on smr?

Thanks! It's 3.5. Where does it say whether a disc is CMR/SMR/Helium?

4TB disk advice (alien.top)
 

Hi,

I am looking to buy a 4TB SATA hard drive. Use case is backup about once a week with and external dock, looking for files every now and then.

The general idea is that I would have two of them, and use the method of storing them with one pebble to indicate where to backup next, so I have one security copy always.

Speed is not important, durability is. What should I buy?
