With rsync 3.1.1 (on debian), using the "backup-dir" option creates a tree of
empty folders inside the backup repository. This doesn't affect the transfer
(all files and folder are copied anyway).
Example:
----
rsync -rtvhPx --delete --stats
--exclude-from=/home/pierre/scripts/ExclusionRSync --backup
--backup-dir=/media/pierre/g2/sauvegardes/fichiers_supprimes_pierre
/home/pierre/ /media/pierre/g2/sauvegardes/sauvegarde_pierre
----
The previous command (launched the first time) recreates the whole structure of
folders inside the "/media/pierre/g2/sauvegardes/fichiers_supprimes_pierre"
backup-dir). These folders are empty and the files are present in
"/media/pierre/g2/sauvegardes/sauvegarde_pierre"(destination).
It seems to be a bug because the backup directory should contains something if,
and only if, I delete files or folder. But it is impossible to delete something
during the first backup; nonetheless, the backup-dir is full of empty folder
after the first call of rsync.
There are two unanswered messages on Unix.SE describing this bug ([1] and [2]).
