Comparison of content of two folders on remote cluster with rsync command

There is my home directory and its backup on the remote cluster.I used rsync command to check if home directory and its backup are completely identical: rsync -rvnc data/ data2 >rsync_out-4.txt 2>rsync_outErr-4.txt The full content of the rsync_out-4.txt file is: sending incremental file list skipping non-regular file "dorado-0.8.3-linux-x64/lib/libaec.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libaec.so.0" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libcublas.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libcublas.so.11" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libcublasLt.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libcublasLt.so.11" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libcudart.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libcudart.so.11.0" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libhdf5.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libhdf5.so.8" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libnvToolsExt.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libnvToolsExt.so.1" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libnvrtc-builtins.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libnvrtc-builtins.so.11.8" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libnvrtc.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libnvrtc.so.11.2" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libsz.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libsz.so.2" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libzstd.so" skipping non-regular file "dorado-0.8.3-linux-x64/lib/libzstd.so.1" sent 156,247 bytes received 1,898 bytes 10.04 bytes/sec total size is 788,734,385,199 speedup is 4,987,412.72 (DRY RUN) The file rsync_outErr-4.txt is empty. 1. Does the output above means that the home directory and its backup are completely the identical? 2. How i can be 100% sure that rsync was executed correctly and successfully finished (in particular that comparison was done for full content of the two mentioned above directories). Is there any indicator of successful run of rsync command which i can find in the rsync_out-4.txt file?
