rsync uses a heuristic based on file times and sizes to compare files. to compare file content use the --checksum feature (computationally expensive to run)

- Dylan16807 4y agoRsync can checksum a lot of megabytes per second. In general I'd say the disk IO is much more expensive than the computation.
- srvmshr 4y agoYes but it doesn't answer why rsync & checksum pass the set of files as same, but diff reports them different.
