Hybrid backup Sync error naming rules

[paolo.martella]

Hello,

I am using Hybrid Bakcup Sync to backup my folders to OpenDrive Cloud.
I got several errors like:
[CloudBackupSync] (Backup) job [Backup Open drive 2] cannot upload file /share/Documenti/Comune/Fotografie/2005/2005_07_02_Courmayeur/Immagine 041.jpg because the path is invalid. Please check the naming rules and retry again

The strange thing is that with files;
/share/Documenti/Comune/Fotografie/2005/2005_07_02_Courmayeur/Immagine 040.jpg
and
/share/Documenti/Comune/Fotografie/2005/2005_07_02_Courmayeur/Immagine 041.jpg

the backup works properly.

Please could you help me in finding where the problem is?

Thanks

Paolo
