3-2-1 strategy with HDDs only?

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?

4TB disk advice

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?
