Run a big copy operation with Rsync

Run below as root or superuser:

rsync -avhW $FROM_DIR $TO_DIR > ~/copy.tmp

• -a Archive mode (recursive, copy symlinks, preserve permissions, preserve modification times, preserve group, preserve owner, preserve device files).
• -v Verbose mode (print path of each file copied).
• -h Human readable (format numbers to be human-readable).
• -W Whole file (copy files whole, do not use transfer delta algorithm).
• $FROM_DIR Source directory, with trailing slash. E.g. /mnt/Media/Media/
• $TO_DIR Destination directory, with trailing slash. E.g. /mnt/TEMP/Media/
• > ~/copy.tmp Sends stdout to a file which can be used for scripting.

Send a brief email notification when copy complete

Send a verbose email notification when copy complete

This should be set to run after the copy completes (e.g. in a script, or with an &&).
