Windows Backup error: "The mounted backup volume is innaccessible"
Prior to upgrading to ReadyNAS 6.9.1 my backup process was functioning perfectly. I had File History backing up to a shared folder and I had system images running weekly as well utilizing the "Windows 7" Windows Backup app in Control Panel on Windows 10. After the update, I have never once been able to get a system image to work properly, although File History continued to function. I thought with the release of 6.9.2 the issue would be resolved but it still isn't working. I have tried everything and read every post in the community before writing this request for help, but to summarize I have tried the following:
1. Reformatted the ReadyNAS with brand new drives and recreated the shares/accounts.
2. Downgraded the firmware back to a variant of 6.8.x.
3. Followed the guide EXACTLY here https://kb.netgear.com/24913/How-do-I-back-up-my-Windows-PC-to-a-ReadyNAS-OS-6-system-using-Windows-Backup-and-Restore including creating a username "John" and giving the account a 1234 password for testing.
4. Tested doing an image backup on a hard drive connected via USB (which functioned perfectly).
When going through the config process of Windows Backup I am able to select the NAS as my network location and select the folder that I have created as the Share from the ReadyNAS interface (WindowsBackup is what I have named the share). Windows Backup then asks me to confirm the username/password. If I supply a bad username/password combo it notifies me. I then tell the app to start the backup and below is a summary of what happens:
From start to finish it takes about 3 minutes for the backup job to fail.
The strange thing is that if I browse to the backup location on the NAS I can see the following:
Data is being written, and then it errors out.
The version of Windows I am running is:
Any help would be greatly appreciated. I login to my computer using a Microsoft Account, which happens to use the same email as my MyNetgear account, but with a different password, so I'm not sure if that is causing any issues. I know that before I upgraded my account to a ReadyCloud account things were easier because my new ReadyCloud account wasn't automatically downloaded to my ReadyNAS so I could use different passwords and access my shares via SMB without an issue.
Thanks in advance to whoever is able to help!

Hi Nathann
I just tried it on a Windows 10 with the same version and it completed with some files skipped which might be files in use.
NAS 526x on OS 6.9.2 runs fine with Windows backup. Since you followed the instructions on the article it should just backup with default settings.
How large is your PC data volume? I think connection to backup destination NAS times out. Have you tried using a different computer for testing?

Marc,
Thanks for attempting to help! The amount of data on my main PC is 343 GB.
I have a VM running in Parallels on my Mac. Version of Windows 10 is 1709 Build 16299.125. The data on the hard drive in the VM is 16 GB. I began the backup setup process and connected it to the NAS using the same username John and the password. I then began the system image backup and it errored out within a minute or so with the following error message.
I ran the backup a second time (as this was the same first error I received on my other computer as well) and this is the result.
Same error I received on my main computer.
What can you suggest I try next?
