Recent versions of rsync support zstd compression, which can improve speed and reduce the load on both sides. You can check if your rsync supports that with "rsync -h | grep zstd" and instruct to use it with "-z --zc=zstd"
However, compression is useful in proportion to how crappy the network is and how compressable the content is (e.g., text files). This repo is about backing up user files to an external SSD with high bandwidth and low latency, and applying compression likely makes the process slower.
- greggyb 4y agoCompression is useful even with directly attached storage devices. Disk IO is still slower than compression throughput unless you are running very fast storage. If your workload is IO-bound, then it is quite likely that compression will help. Most people, on their personal machines, would likely see IO performance “improve” with filesystem level compression.
