Hola I have a year+ old My Cloud 3 TB and using the Smartware Pro software to do my backup. My PC is a Dell Inspiron 17 running Windows 8.1, WiFi from a Linksys EA6900 router. I have had some issues with Smartware/ Smartware Pro completing backups. I am not sure that it has ever worked correctly. I can start a backup either in continuous or timed. Here is what is happening; once the backup has started it will progress some times quickly or some times over hours. The amount of files to backup is 252+GB. Let me first say that I have deleted the program now 3 times, Delete, reboot, run a cleaning with two different programs, download a new Smartware and installed. Open, it will categorizes my files, set it to do either continuous or timed backup, does not seem to make any difference which one it ends up the same way. If using timed backup go to backup now. This is how the last one went, open, files are categorized, close window open Smartware, start backup at 9:17, by 9:53 it has backed up 209.37GB of the 252+GB (some times as much as 4 hours to reach this point). There are 42.07 GB (more or less) of the files listed as pending backup each time it stops.Than as with the last 3 other attempts as well as the original time it stops. I have let it sit for up to 3 hours with out any more backup accruing. As I said I have deleted and reinstalled 3 times only to this same end. The only way to start a backup again is to delete the program, do new downloads and reinstall Smartware. Each time I have been unable to use my key to upgrade to Pro. The screen on the Home tab does not show the key sign where you go to add your key #. So after the first time I deleted I have not used the Smartware pro in trying to do any of the backups. It stopped at 209.37, the highest was 209.51 completed. I am at a complete loss. And a bit worried because I have no backup of my files other than what is stored on the My Cloud physically. I have talked with support, they have taken control of my PC and repeated the same steps as I only to the same end, no complete backup. I would be grateful for any input. As well I can post screen shots, or any other info needed to help any one find an answer. Thanks much!
