[[!tag obnam-wishlist]]
Obnam should, at least optionally, use fsync or other methods to ensure
that everything gets committed to disk by the kernel by the end of a
backup run. --liw
I want this to not have a huge performance impact, though. Learning
from the lessons of dpkg, sqlite/liferea/firefox, etc, and using fsync/fdatasync
and `sync_file_range` in the right ways is going to be necessary. --liw
Not doable over sftp, of course. --liw
