Best strategy for full NAS backup under 4TB?
I have two Pro Pioneer systems that were set-up three years ago and are due to have their drives replaced with larger capacity drives. Both systems have under 4TB of data. Both have had regular USB...

Update:
Fully backed-up to an HFS+ USB3 drive using Carbon Copy Cloner on a Mac. I connected via .afp using the tip in this article:

The overhead of CIFS drops my transfer rates down to ~66MB/s. (I get ~110MB/s over .afp) so this trick cut my backup time roughly in half. Even so, ~4TB took about 20 hours due to CC Cloner's checksum verification overhead. So I guess that's as fast as I can go. Good thing most backups are incremental.
BTW, high recommendation for Carbon Copy Cloner to all Mac users. It has no problem cloning network volumes and the support from developer Mike Bombich is outstanding.
Now time to get some new disks! :D
