obnam mount (the FUSE plugin) can't handle a client without
non-checkpoint generations. This is unfortunate, even if it is fairly
unlikely to happen. Should be easy enough to fix.
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?
Obnam needs tests for using every filesystem type available as live data or repository.
Not sure how to arrange that without root access, but there's a need to do that.
Obnam has no test for what happens when the filesystem fills up.
Ben Kelly reported on August 31, 2012, that he's seeing crashes due to file descriptor leaks. See list mail archive for logs and suggested patches. I have not been able to reproduce this, however. --liw
