Outside of IT, "legacy" is usually a good thing. In sports, players and teams hope to build a legacy of winning, of making big plays in the clutch! But in IT, calling something legacy makes it sound old and crusty, like it might smell of arthritis cream.
There are many vectors to look at when protecting digital assets. The top concerns in my mind are backups, and security. I don’t think either are classified as sexy, but neglecting them tends to end poorly for your company, and possibly your career.
I’m still searching for that person that tells me they got into IT because they wanted to do backups. If you meet this person at a dinner party, get ready for a lively conversation! Nothing like discussing retention policies to get the party going!
