I am trying to back up some files via rsync to an external SSD drive via USB3 - just copying new files over the past few days. The problem is that the copying is very slow - around 30MB/s. Assuming that the port and the drive are actually USB3, what are some other reasons for the slow copy?

For reference, here is my command:

# find and copy all files modified in the last 14 days that are greater than 200Mb

rsync -avz --progress --files-from=<(find /mnt/user/Movies -mtime -14 -type f -size +200M) / /mnt/disks/Crucial/Movies

 

Try without -z (compression)

Thanks. Made a big difference - going at ~100MB/s now.
