Need help finding a specific HN article

I need help finding an article posted on HN in the beginning of this year. Probably it was on the first page. Also it could be a top comment in some "Ask HN" thread.

I don't remember title/site/author, but I remember what is it about. I have searched HN (site search, DDG, etc.) and all my bookmarks and browsing history for hours but still can't find it.

The article was a blog of some person describing how he set up a system to backup all their browsing history, chats, bookmarks, etc. The post included an image showing the architecture of all this. As I can remember he was backing up telegram chats to SQLite database for example. The author also mentioned that all this system took him a long time to create.

Thank you very much in advance!
