What is typical backup time for ~ 600 GB to external USB 3.0 drive?

Thread needs solution

I have a WD My Book 3TB external drive connected via USB 3.0. The rest of the PC is Intel Core I7-4790, 16GB of RAM, internal SATA 3.0 hard drive split into six partitions, all of which are to be backed up.

Using ATI 2015 last night (latest build), a full backup took approximately 7.5 hours. The resulting .tib file was about 595 GB. Backing up the same system to an internal hard drive used to take somewhere between 2-3 hours (I don't remember the exact number right now).

Is this typical for backing up to an external drive? Or is something mis-configured in my system?

For comparison purposes, I started a NovaBack full backup this morning, to the same external drive. It's estimated to complete in about 11 hours.

Thanks - Jim

I am not using Acronis cloud backup.

You have about 22MB/s, which is more like a USB 2.0 backup speed.

When you copy big files from your main disk to the USB disk, what average speed do you see?

I don't understand the question. Based on your own statements Acronis finish the same task in a shorter amount of time. An internal disk has a great deal more bandwidth then an external drive connect by USB 3.0.

The difference in time can be explained by different compression algorithms
