Error restoring backup data!

I've got the following error while restoring the data:

Exception occurred: java.io.CharConversionException: Last Entity imported :[GenericEntity:Action][created,2004-05-26 21:51:13.0][issue,15107][type,comment][body,I suppose that the problems this issue describe is not actual now.

What's the purpose of backup without the way to restore the data?
