rsync with more efficient compression, hash algorithm

rsync 3.2.0 and newer supports more compression and hash algorithms. zstd compression is well suited for slower network connections [ tens mbit/s ], lz4 – for faster.

xxh3 hash is worth using regardless of the network speed.


rsync -zav --progress --compress-choice=zstd --compress-level=3 --checksum-choice=xxh3 user@sourceServer:somewhere/ ./
