[[!tag obnam-wishlist]]
This is an idea for optimizing Obnam.
Store MD5 of string containing names + relevant metadata of all
files in a directory, then re-compute that when backing up a
directory: if checksums are same, then no file in the directory
has changed, and there's no need to check each of them separately,
saving many tree lookups
Consider only non-dirs, since subsubdir can change without it being visible
at grandparent level. Thus, recursing is always necessary.
