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?
Since your data is just 2tb. Just get M-Disc. Those suckers last for 1000 years according to the manufacturer. No organic material, its like carving onto stone.
