I have a 56 TB local Unraid NAS that is parity protected against single drive failure, and while I think a single drive failing and being parity recovered covers data loss 95% of the time, I’m always concerned about two drives failing or a site-/system-wide disaster that takes out the whole NAS.
For other larger local hosters who are smarter and more prepared, what do you do? Do you sync it off site? How do you deal with cost and bandwidth needs if so? What other backup strategies do you use?
(Sorry if this standard scenario has been discussed - searching didn’t turn up anything.)
Lto tape. But I only have 15tb
It quickly becomes cost effective when you actually need the data to be safe. Far easier to have off site backups. I have never had a problem , but I like to have offline backup. Most of the time my data is static. So I am only backing up projects files ans changes for the most part.
If you have 40+ tb of dynamic data I can’t help there.
