Obnam seems to be storing metadata quite inefficiently. I did this:

• create a directory tree with about 1.3 million empty files
• back that up

The data is about 500 megs (directory entries); the repository is about 82 gigabytes.

Where is the space used? Can we store it more efficiently and if we do, does that have an impact on runtime?

Workaround: use compression. Proper fixes are going to require FORMAT GREEN ALBATROSS. done --liw
