...ile. with strace on rsync, I was able to see that the whole root filesystem is passed in order to check checksum of all files, even if I don't have to change them... why? This operation should be already done when I created batch. So is it possible to bypass the entire rootfs analysis (with chechsum, or date and size)? Is it possible using batch only to modify changed destination file without considering the other ones in any way? I tried with include/exclude options, but the whole rootfs is scanned the same. I also tried to search that on this forum, but without success. I don't wan...

...a lower block size standard deviation for a given block mask. The overall trend of the ratio between the average and standard deviation is pretty much independent of algorithm selected, but there is an approx 5-10% increase in standard deviation as a percentage of average block size for the simple chechsum calculation relative to the rsync checksum. 4. The large scale behavior of the ratio between average and standard deviation is definitely dependent on Block Mask Size. Higher mask values result in larger standard deviation - but is non-linear, and appears to taper off to about 85% for the simple...
