Backup job path error

[Loose]

Dear All,

 I having issues when I want to setup a remote backup job for my file server. The source path is giving me error connection and I ready need to backup. I'm running firmware 4.1.16.

Kindly assist with host & path guide.

Is the source the readynas, or is it the remote device?

Is the remote device connecting over the internet, or is it local?

What operating system is the remote device using, and what backup protocol are you using in the NAS?

Are you using the device's hostname or are you using its IP address?

Dear Guru,

The source is our file server running windows server 2008 R2.

It local but connected to our office network. Kindly assist.

Regards

[StephenB]

Are you using a NAS backup job?  If so, please post the settings.

Also, is SMB 1.0 enabled on the Windows server?

Try entering \\10.11.21.20 into file explorer on another windows machine, and take a look at the share name.  That's the share name that should be entered as the backup job source.

Also, make sure you can actually access that share with from the Windows PC using whatever credentials you are using in the NAS.

Generally I find it more convenient to run a backup utility on the PC with the  NAS as the destination. I use Acronis TrueImage for this.
