also called site backup
A stored copy of a site or data that can be restored.
A copy you can go back to.
What It Is
Backup is a Technology item, filed under Hosting. The working definition is simple: a stored copy of a site or data that can be restored.
It is a mechanism rather than an opinion: set up properly it behaves predictably, and set up badly it fails just as predictably. That definition is deliberately narrow — the narrowness is what makes it usable.
How It's Used
Backup comes up in build decisions, tooling and the plumbing behind a working system. In real work it sits close to Website Maintenance, Version and Hosting. The practical test is whether it is configured, documented and actually working.
Why It Matters
Getting Backup wrong is expensive in a quiet way. When it is unclear, small technical debts compound into a rebuild. Deciding it deliberately costs one conversation. Leaving it undecided costs several.
Think of a tool in a drawer — dull until the moment you need exactly it. A copy you can go back to.
Termshift™
How the meaning shifts depending on who is using it, and where.
Inside the industry, Backup is used tightly and assumed to be understood: a stored copy of a site or data that can be restored.
Away from the jargon, it is a copy you can go back to.
The Bottom Line
Backup pays off when it is specific and costs you when it is not. A copy you can go back to.
