Incremental restore vs full restore
Bupstash supports incremental restores - it will only download files it detects have changed. This may be faster, I am not sure if other tools support this.
This sounds like a really cool feature. But, out of curiosity, what is the use case for such a feature? An easy way to restore to an earlier snapshot rather than disaster recovery?
Bupstash doesn't support mounting a filesystem as shown in the table - but as an alternative you can 'checkout' directories more like git and browse them, to do these checkouts efficiently it has incremental restore. It also functions as a way to resume restores that were interrupted.
Duplicacy always does incremental restores. It will not download data that is already there unless you tell it to overwrite.

Kopia can also ignore restoring existing files, but I am not sure that is the same thing as what @andrewchambers is saying bupstash has. Ignoring existing files is not the same as only restoring a file if it has changed.
