system is installed with Ubuntu 22.04.1 LTS.
When running command "rsync -avn --delete-before "
i see at the end following information:
"sent 5,941,061 bytes received 588,133 bytes 72,145.79 bytes/sec
total size is 973,856,677,250 speedup is 149,154.20 (DRY RUN)"
My assumption is, that those 6MB are the chars sent when listing files to be deleted and so on.
After this dryrun i started a real run:
"rsync -av --delete-before "
and the output was:
"sent 8,139,216,085 bytes received 581,534 bytes 22,961,347.30 bytes/sec
total size is 973,305,273,035 speedup is 119.57"
My assumption is, that since the last rsync run (which was around 10.December 2022, six weeks ago) i changed data in the amount of 8,139,216,085 bytes, that had to be rsync'd now again. (Also knowing, that only full files are rsync and not just portions of changed files)
Now, when i run "rsync -av --delete-before "
directly after the run above finished, the output is:
"sent 7,186,863,729 bytes received 578,178 bytes 24,078,532.35 bytes/sec
total size is 973,305,273,035 speedup is 135.42"
And, i wonder, what changed during the last rsync run around 7GB of data.
The system hasn't been used, while rsync was running, and nothing has been touched at the source (source and target are two different USB drives, on source i store from time to time data, which later i randomly backup per rsync to USB target drive.)
