pathological permissions
d--------- 88 localbackup localbackup
It was created during yesterday's backup, mirroring the permissions of the
source directory on the Cygwin box. Today, rdiff-backup crashed with the above
error message when transgressing said directory on the destination box.
I would have expected rdiff-backup to do one of the following things:
1. Refuse to backup the unreadable directory in the first place writing an
error message to the log.
2. Backup the unreadable directory and then use chmod on the backup target to
check for changes/store increments during subsequent backups.
Judging from the error message it seems that rdiff-backup was actually trying
to do 2. (calling chmod) but made a mistake somehow.
