If I don’t choose to backup any modules and include a single custom directory the backup fails. FreePBX reports that the backup succeed but the tar.gz file is not generated. If I include just one module the backup file is generated with my custom directory inside it.
My directory has the following rights
[root@freepbx monitor]# pwd
/var/spool/asterisk/monitor
[root@freepbx monitor]# ls -lh
