-- Setting the file size in advance, instead of making every write an extending write, helps improve copy speed in scenarios where the file size is known. If extending writes need to be avoided, you can set a destination file size with `truncate - size <size><file>` command. After that, `dd if=<source> of=<target> bs=1M conv=notrunc`command will copy a source file without having to repeatedly update the size of the target file. For example, you can set the destination file size for every file you want to copy (assume a share is mounted under /mnt/share):
-    - `$ for i in `` find * -type f``; do truncate --size ``stat -c%s $i`` /mnt/share/$i; done`
-    - and then - copy files without extending writes in parallel: `$find * -type f | parallel -j6 dd if={} of =/mnt/share/{} bs=1M conv=notrunc`
