Has anyone got any idea how long backup to external HDD via USB should take? I'm backing up a 2TB NAS with just under 500GB of data onto a 1TB USB3.0 HDD, the backup has been running for over 24 hours now, this seems a long time.
How long should it take?
Thanks
Tim

my test with LS-QVL
64GB USB Fat32
writing to usb 21MB/s
# sync ; time sh -c "dd if=/dev/zero of=/mnt/usbdisk2/testfile bs=100k count=10k && sync"
10240+0 records in
10240+0 records out
real 0m46.738s
user 0m0.030s
sys 0m4.950s
copying from usb to Raid5 with 23MB/s
sync ; time sh -c "cp /mnt/usbdisk2/testfile /mnt/array1/share && sync"
real 0m42.608s
user 0m0.170s
sys 0m4.970s
1. which nas do you use?
2. which filesystem do you use on the usb device
