A few steps are necessary to speed up WD MyBook Live performance.
Login to WD MyBook Live and navigate to "Settings --> Media". There, disable the "Twonky Media Server" by uncheking "Media streaming".
Next, disable "mediacrawler": SSH into your device and issue the following commands:
chmod 644 mediacrawler
This will stop the drive from indexing media files (music or videos).
If you ever want to re-enable mediacrawler again:
chmod 755 mediacrawler
If you want to use rsync
between multiple WD MyBook Live drives, use the following syntax:
sync --protect-args -av --delete -e "ssh -T -c arcfour -o Compression=no -x" "path/to/folder1" "firstname.lastname@example.org:/DataVolume/.../shares/.../folder2/which/contains/folder1/" >> rsync.log
The -e arg will use a weak encryption which is faster.
The --delete arg will delete files on destination, which are not on source
