I have TI9 build 3677 and have not been able to successfully backup using DVD+R media. After putting the first disc in, I get the message: E00070004: Failed to write data to the archive file. A possible reason might be poor media quality I have read through numerous past posts about this error. Apparently this seems to be a common problem with Acronis. I have now wasted over 10 dvds and have tried uninstalling and reinstalling the software with no success. Please help.
