Remember to set R/W access (permissions) to the USB share or you will definitely have problems with local backups failing (big files)or when using more than one USB HDD. The Local backup HDD grows dramatically in size if you used DR3 Restore Points as the Symbolic links can't be supported on a different volume.
can you please clarify the settings you made to get this backups work?
We've exactly this problem with large files on multiple systems. In one case the first USB Disk works, the other doesn't.
Last year we contacted the Syno Support to fix this issue on some of our DiskStations, but they did not tell us how to fix it by ourselves.
