Hi everyone.
In preparation for wiping my ext4 filesystem, installing Kralizec and re-creating the filesystem, I purchased 2 x 5TB USB 3 drives so that I could backup my data.
I'm seeing very slow transfers from my array (RAID6 / ext4) to the USB drive. Attempting to move 2.5TB has thus far taken over 12 hours (still running). The destination USB drive is ext4 as well. It's plugged into a USB3 port. For the transfer, I'm using rsync (rsync -vrh [source] [destination]).
I have about 7 more TB to go after this first run, so I'm wondering if there is perhaps anything I'm doing (or have not done) that might be impacting the speed of this transfer. Any suggestions on speeding it up?
I expected the full backup to take a few days, but give that it's roughly going to be 16-17 hours for 2.5TB, something doesn't seem right there. (FWIW, these are movies.. large files, between 1GB-10GB each).
