clone_sd.pl doesn't properly detect directory existence

[thing4711]

Hi all,

I am trying to backup to LoxBerry SD card to an SMB network drive with the script /opt/loxberry/sbin/clone_sd.pl.
I started using the web interface and after it failed tried to debug it on the console but I can't find out what the issue is.

This is what happens when I run the script:

root@loxberry:/opt/loxberry/sbin# perl ./clone_sd.pl /media/smb/qnap.nas/data_ha/Backup/Loxone/loxberry path 7z

This is the result of some manual permission investigation on the console:

I don't get, why the following block doesn't properly detect existence of that directory...

$destpath_found = 0 if ( !-e $destpath);
if (!$destpath_found) {
    LOGCRIT "Your entered DESTINATION path $destpath does not exist or isn't writeable.";

I forced the script to continue with commenting out the following exit(1); but afterwards there is another issue:

<CRITICAL> Your entered DESTINATION path /media/smb/qnap.nas/data_ha/Backup/Loxone/loxberry does not exist or isn't writeable.
<INFO> Destination device is  () available space 0.0B
<CRITICAL> /media/smb/qnap.nas/data_ha/Backup/Loxone/loxberry (0.0B) is smaller than required space (4.3GB)

Is it possible that the issue is with the fact that it is a network drive (cifs mount) ?
Is there any idea how I can alter the script to make it function ?

Thank you in advance.

Are you sure there's no access right problem on NAS side? Or any "max filesize" problems on NAS side?
