I have a backup folder owned by a system user (mongodb) and chmoded 655. When I try to create files in it, it raises a permission issue:
root@maquina:/var/backups/mongodb# su -s /bin/bash mongodb -c "/usr/bin/touch test.txt" /usr/bin/touch: cannot touch `test.txt': Permission denied
Chmoding to 755 enables me to create the file.
I guess I probably need to tweak the privileges (+X ?) but cannot find how.
Can anyone shed some light on this ?
