3-2-1 Backup

I'm always beating the drum on backups. My last post was 2 years ago but it's still pertinent.

It seems like not everybody is following the 3-2-1 backup strategy (archive.org).

It's personally traumatic when it's YOUR data that is lost but when it's an enterprise's data, it's even a bigger problem.


Let's start with the headline:
PBS broadcaster loses access to 50TB of data comprising 70 years of TV history after contracted cloud storage vendor goes defunct
The whole ugly story is here (archive.org).

It seems like Nine PBS skipped right down to the "Cloud Storage" section of 3-2-1. If they had paused for a little bit on the "External hard drives" section they might not have had this problem.

"Might" is the operative word here because they still should have tested their backups.
