Problem backing up settings on Lumia 630

[Jagadeeshvanum]

I've successfully backed up settings on 30-07-2015. Since then I've been trying to backup, it reaches 100% and then I get "The server connection was lost and the backup failed. Please try again later." I did 6 soft resets. Deleted temporary files. These last 5 days I've added a lot of custom words to my dictionary, all I want to do is get those backed up.
Edit: Please someone help me. I don't want to do a hard reset. since 04 th August I've been trying to backup at least twice a day.
