I was worried about same issue as well, although mostly in the area of website/knowledge screenshots as my desktop screenshots are pretty low in quantity. Recently decided to selfhost Archivebox.io app. It feels a bit rough but delivers decent results. I love the PDFs and single file HTML dumps. Managed to secure some very old sites I relied on for ages but never really saved them. All can be refreshed, dumped again, tagged, searched. UI is actually a Django admin page.
