Unison syncs two sets of files so that both are identical, sort of like a two - way version
of rsync (which is basically what Unison is).
Not exact matches
The tricky thing with
rsync is that you need to use a relative path when you are trying to exclude things, because when it tries to match the exclusions it won't use the first part
of the path for the match... it's weird.
When they discovered more than 42,000 patient records and millions
of patient clinical notes exposed on a misconfigured
rsync backup, researchers at UpGuard responsibly set out to notify the entity to secure their data.
