Windows Backup issue with NetGear ReadyNAS

I have a problem with WindowsBackup. I'm trying to use it, for the first time, to backup to NAS (Netgear Readynas RN104). After it works for some time (the files and folders are created on the NAS), it suddenly stops with an error : 0x81000039. So far I have tried:

1. Mapping NAS drives to local volumes

2 . Changed the NTLM authentication

3 . disable automatic detection of receive window

4 . LAN connection using a cable Ethernet ( usually I'm connected by WiFi)

5 . Disabling the Windows Firewall


The same thing happens at two different laptops ( working with Windows 7). Unfortunately , I dont have the opportunity to try on another computer or other OS. Copying large files back and forth to the NAS works without problems.

On another forum someone told me that Windows Backup have a issue because the file system used by Readynas is Ext3 or Ext4 and despite CIFS it's still a problem. I dont understand why should it be an issue as CIFS makes it irelevant for Windows Backup with the the FS. Moreover, I guess most NAS system run Linux and thus use EXT FS.

    The 104 uses BTRFS not EXT4

    Have you considered trying different backup software?
  • Does it make any differance that it uses BTRFS? Is it the reason it doesnt work?
    I did consider using another software, but I dont want to buy/install another soft if windows supposed to do it ...

    I was just pointing out that the NAS is using a different filesystem to what you thought.

    Have you tried contacting support to see what they suggest?
