Is rsync multi threaded?
It uses rsync algorithm and is designed to use up to 5 threads when backing up a folder structure. Although more threads are possible, I/O read/write becomes a bottleneck with more threads. Note that Syncrify does not use rsync’s binary.
How do I rsync between two servers?
Rsync is a great way to synchronize files between servers or to simply move files between servers without the need of FTP. It connects two servers via the SSH protocol, allowing for the transfer of data between them. The rsync daemon, covered later in this article, uses its own protocol and runs on a specified port.
How to parallelise rsync using GNU parallel-Unix?
In conclusion, as @Sandip Bhattacharya brought up, write a small script to get the directories and parallel that. Alternatively, pass a file list to rsync. But don’t create new instances for each file. Run the rsync –dry-run first in order to get the list of files those would be affected.
Why is rsync slower in parallel than SCP?
Compare it with the speed of scp (for example). rsync is even slower at raw transfer when the destination file exists, because both sides have to have a two-way chat about what parts of the file are changed, but pays for itself by identifying data that doesn’t need to be transferred. A simpler way to run rsync in parallel would be to use parallel.
Why is rsync so slow at raw transfer?

A simpler way to run rsync in parallel would be to use parallel.
What are the options in the rsync command?
Some common options used with rsync commands. -v : verbose. -r : copies data recursively (but don’t preserve timestamps and permission while transferring data. -a : archive mode, archive mode allows copying files recursively and it also preserves symbolic links, file permissions, user & group ownerships and timestamps.
