This **may** indeed be a myth (for a long time now) re-cited again and again and - could no longer be valid today - could apply only when deleting explicitly named files but not deleting the complete folder (as we need to do in "Back in Time") At least I could not find a holistic benchmark with many files and different scenarios (file systems, rsync'ing locally vs. over network, snapshot sizes, number of files, file sizes, rsync and rm versions...) Q: Does `rsync` provide a test case that I could use as basis to prepare such a holistic benchmark? > But now that I am hearing > that rsync actually adds a bunch of pointless chmods to the process.

Just by strace'ing I saw `rm` mainly calls unlink, `rsync` does not. -- Please use reply-all for most replies to avoid omitting the mailing list.
