Details:
I created some remote backups and then set up a "secure" enviroment with the
help of --restrict and --restrict-update-only. In the directories where the
backup was created and then incremented (before I setup this flags)
everything works as it should, but (!!) in the directories where there hasn't
been an increment (till now) I now (with the restrictions set up) get the
following error:
Traceback (most recent call last):

rdiff_backup.Security.Violation:
Warning Security Violation!
Bad request for function: os.mkdir
with arguments: ['/target/backup/dir/rdiff-backup-data/increments']
The solution would be to allow os.mkdir to create directories if they are in
the rdiff-backup-data subdirectory inside of the restricted path! Or to
create ALL subdirectories inside rdiff-backup-data that could be needed at
some point in the future when the program is executed at the first backup!
