After backup: Destination is read-only?

I still suspect the dirty bit somehow got set. If it happens again, try writing a file to the drive manually and see if that works. If it is mounted read-only then it will fail.

Yes, I'm not arguing that. But I would like to find the reason for the dirty bit to be set. If verified that all directories are read/write before I connect it to the NAS. Might be onto something with the long path and file names. Just started splitting up the backup, with one backup task for each share. Two smaller ones have succeeded sofar. I now scheduled the other shares, except the share where I suppect the long file names and paths reside. Will try to pin that down some more, if all the other shares have succeeded. Will take a while before everything is copied though, so more on that tommorow.

USB backup is reasonably fast on the 516, but it should be just as fast to back up over a gigabit network. USB 3.0 would be faster over the network. Speeds are here: http://www.smallnetbuilder.com/nas/nas- ... l=&start=1

Would think so too, but can't achieve it in my setup. What would take 8 hours on a disk connected directly to the NAS, takes over 23 hours when copying over the network from the NAS to a USB disk on the PC. Can't really explain why this is so slow.
