• -z: Compress the files before sending. This is ideal for transfering over low bandwidth links, but be wary of CPU usage.
• -a (archive): Preserves everying such as permissions, ownership, file modification, and etc.
• -r (recursive): Copies data recursively, but does not preserve timestamps and permissions when transferring data.
• -n (dry run): Dry run of copying. Does not actually copy anything, but it is good to use as a test before offical run.
• -h (human readable): Output in human readable output.
• -v (verbose): Prints the files.
• --delete: Remove all files that are not in the destination directory that is not in the source directory.
• --progress: Prints a progress bar.
