Not sure if this is everything. For examples, if i backup /home/op/w/plakar/btree i get this info vfs back:

Which seems overall good to me, except for the Directory.{Min,Max}ModTime and the size:

$ du -h btree
48K	btree/
$ ./plakar info vfs d0cb6696:/ | grep ^Below.Size
Below.Size: 26 kB (26442 bytes)

But at least the size are matching:

$ ls -lah btree

Ah, i forgot to comment the diff itself! The main issue comes from the separation of file and directories, since I was iterating only on the file children, not the subdirectories, so we were missing all the accounting for them.

Looks good. Man this was broken beyond recognition.
