Which means that in any case the ETA estimation might be far off. And counting files will count the same progress for one big delta and another one with small delta. I recommend to monitor the number of files transferred, since the amount of data transferred is not correlated to the size of files but on the delta between the source and destination. You can with 'pv' ( apt-get install pv with Debian and ubuntu). See also for specific version differences (scroll down and check out the Release News links). Incremental recursion can be disabled using the -no-inc-recursive option or its shorter -no-i-r alias. See also the -delete-delay option that is a better choice than using -delete-after. Because of this, the default delete mode when you specify -delete is now -delete-during when both ends of the connection are at least 3.0.0 (use -del or -delete-during to request this improved deletion mode explicitly). These include: -delete-before, -delete-after, -prune-empty-dirs, and -delay-updates. Some options require rsync to know the full file list, so these options disable the incremental recursion mode. It is also only possible when both ends of the transfer are at least version 3.0.0. This incremental scan only affects our recursion algorithm, and does not change a non-recursive transfer. Beginning with rsync 3.0.0, the recursive algorithm used is now an incremental scan that uses much less memory than before and begins the transfer after the scanning of the first few directories have been completed. This tells rsync to copy directories recursively. The following is from the rsync manual (source - ): As you would expect, the more files there are, the longer the delay will be and the more memory it will require. Building the entire file list ahead of time is more memory-costly and it can significantly delay the start of the actual transfer. This applies to the number of files - it does not report any progress based on file sizes. Since it will know all files before starting, it will give a better report of the overall progress. This will build the entire file list at the beginning, rather than incrementally discovering more files as the transfer goes on. The options described below were introduced in that release on March 1st, 2008.Īlong with -info=progress2 you can also use -no-inc-recursive option (or its shorter -no-i-r alias) to disable incremental recursion.

The following applies to rsync version 3.0.0 and above.
