Ready NAS 202 "Failed to upload file", Reason: Gone

Hi there

I have just installed a new ReadyNas 202, bacause I have had too much trouble with my STORA, and wanted a little more sterdy setup... but I must be doing something wrong, because it isn't much better.

I have set up a synchronization backup of a specific folder on my harddrive, which works for some time when I start the computer, but after a while it starts throwing these kind of errors. I'm working on Win10, so it gives me a ring every time, and if I close the message, it just pops right back in my face. I checked the harddrive, and the file is still there, so what does "reason: Gone" mean?

Does any of you guys know a nicer way to handle the backup folders, than the plug'n play solution from Netgear? These are my concerns:

• I cannot backup a drive on my computer... only folders
• When I have first set up the sync folder, then I can't figure out how to change the setup... what if I move my local folder, rename it or suddently want to backup a sub or parent folder instead?
• I cannot get rid of the errors or resolve them
• When clicking on the error message, I should be sent to the error folder, instead of root folder
• If LAN fails, the windows app doens't recognize the device on the LAN when the network is up and running again
• Neither does the browser app

System info:

• ReadyNAS 202
• Firmware 6.4.1
• 2x 2TB NAS harddisks from Seagate
• Windows 10 PRO
• ReadyCloud Client v. 1.8
