Data-backup unmounts backup-folder

NethServer Version: 7.3.1611
Module: backup-data

I have the following situation.

I created 2 ftp users. They are used for backup of wordpress and nextcloud data (on external machines not the local nethserver machine). I chrooted the home path of these users to /mnt/backup/ftp/nextcloud_ftp and /mnt/backup/ftp/wordpress_ftp.
The folder /mnt/backup is an external HD which is mounted at system start.

Now the problem is, that /mnt/backup gets dismounted after data-backup and now the ftp users cannot access their homedirs.

I there a possibility to disable the unmount after data-backup?


If you use cifs that’s the event executed
