No such file or directory exception while doing backup

[fharold]

Hi,

I am using your bundle successfully for a few month now but I only used it on my debug server. But I do not know why I can't do a backup on my production server as I have this exception occuring. My environment is the same on the debug and production server (Debian 7), using php 5.6.24 and Symfony 2.8 LTS

Do you know how can I fix this ? :( Please do not hesitate to ask me more details as it is my very first issue on a public repo. Thanks for everything,

Harold

The logs are :

[2017-02-20 10:58:14] app.CRITICAL: [dizda-backup] Unexpected exception. {"exception":"[object] (UnexpectedValueException(code: 0): RecursiveDirectoryIterator::__construct(/var/www/html/api.hipok.com/app/..//dev): failed to open dir: No such file or directory at /var/www/html/api.hipok.com/vendor/symfony/symfony/src/Symfony/Component/Filesystem/Filesystem.php:435)"} 
Something went terribly wrong. We could not create a backup. Read your log files to see what caused this error.

The configuration :

    # By default backup files will have your servers hostname as prefix
    # such as: hostname_2014-01-01_21-08-39.tar
