How long should it take to backup 4.2 TB of data to a external USB attached Disk
I am running firmware 6.5.0-T338.
I attached a Toshiba external 5TB hard drive to my NAS 516 rear USB 3.0 Port. The drive is formated using NTFS.
Created a incremental backup job on the NAS.
I started the backup job 7 days ago and it is not finished yet. There is currently 3.5 TB of data copied.
How long should it take to backup 4.2 TB of data.
This is taking longer than I expected.

I measured about 24 MB/s on an RN102 with T322 ( https://community.netgear.com/t5/ReadyNAS-Beta-Release/6-5-0-T322-RN100-series-front-port-USB-performance-is-sluggish/m-p/1061142#U1061142 )
Though that was with an SSD drive, and the file sizes definitely matter.
But at that speed, your backup would have taken about 55 hours. You seem to be getting something around 6 MB/s. Is the toshiba a USB 3 drive? Or USB 2?
The external drive is a Toshiba 5TB Canvio Desktop External Hard Drive P/N hdwc250xk3j1.
According the the specs it is a USB 3.0 drive that is also USB 2.0 compable.
Here is a link to the Toshiba web site.
