rdup vs Bup

rdup

The only backup program that doesn't make backups! (by miekg)

Very efficient backup system based on the git packfile format, providing fast incremental saves and global deduplication (among and within files, including virtual machine images). Please post problems or patches to the mailing list for discussion (see the end of the README below). (by bup)

GitMounter: A FUSE filesystem for Git repositories
2 projects | news.ycombinator.com | 28 Nov 2023

The presented idea (one folder per commit, as FUSE fs) seems indeed largely impractical.
But there are good uses for mountable "git like" repos. For example for backup systems.
