Home folders: getting "source and destination cannot be the same" even when they aren't

Hello,

I'm trying to create a backup job for the Home folders on a ReadyNAS 312 going to another NAS on my LAN. I'm getting the message "Source and destination cannot be the same. Code: 7003020008" even though the source is on the 312 where I'm creating the job and the destination is on a different NAS.

Running firmware 6.4.2.

I have other backup jobs for other shares on the 312 going to the same external NAS. These run without errors. But for the Home folders, I can't even create the job.

The backup source is "Home Folders"

The destination uses the Windows/NAS protocol. I configred the NAS IP and destination share. "Test connection" is successful.

When I click 'Finish' I get the error "Source and destination cannot be the same. Code: 7003020008" and the job isn't saved.

I have other jobs with the same configuration that are saved and run without errors. My ReadyNAS 312 is named "NAS01". For backups, on the other NAS I've created a share "NAS01" with folders for the different backups I want to run.

So I have a job with the NAS01 source "Share1" and the destination path "//[other nas IP]/NAS01/Share1". I have another job with source "Share2" and destination path "//[other nas IP]/NAS01/Share2" and so on. For the Home folders job the source is "Home Folders" (selected by browsing the NAS) and the destination path "//[other nas IP]/NAS01/Homes".

Any ideas?

Thanks.
