Correct, Timelinize is not a backup utility, but having the copy of your data in your timeline acts as a backup against losing access to your data sources, such as Google Photos, or your social media account(s), etc. As opposed to simply displaying data that is stored elsewhere.

But yes, I think the likes of what Ente is doing is interesting, though I don't know the technical details.

Data content hashes are pretty appealing too! But they have some drawbacks and I decided not to lean heavily on them in this application, at least for now.
