I am currently using “rclone copy X G -v --stats 10s” which works well.
This results in multiple files being uploaded at the same time. I only have a slow upstream connection and I am copying large files. Just copying one file typically takes 8 hours for these large files. If two files are copying concurrently it means I might have to wait 16 hours before even one is completed. This long transfer time increases the risk of a failed copy due to a network interruption.
Other than specifically specifying the file name, is there a switch to control the number of files concurrently copying?
