Backup doesn't finish

Hi.
I'll try to explain this, but it's not that easy since my english isn't the best. So please, forgive me.
I have the auto-backup for the data on my Z5C, so every night, when I charge it, the backup starts, but that's it. It stops at the beginning and the only way I found to make it complete the backup is opening the notification of the backup (which says it's still doing it) and then, magically, it really starts working and doing the back up. This is so annoying for me and I have no idea on what it depends on.

Any suggestions?

Thank you
