I was also a bit confused and expected something like grype -https://github.com/anchore/grype
I do software development for living and do not have any special backups for dev related files other than git. For general office documents I use Seafile (selfhosted Dropbox equivalent) and have redundant copies of important files on multiple machines and the central Seafile server. If I need real backups with the ability to restore a set of files in a specific point in time I use restic.
