Is recent rsync (which does not require full list of files at start) able to cope with such huge amount of files?
Yes, rsync 3 can handle maildirs totaling millions of files. We use it for that purpose and have not hit limits (we did hit limits in rsync 2.6.x). As others have said, make sure you use a wrapper that ignores "file has gone away" errors.
rsync 3 is available in etch-backports. -- Robert L Mathews, Tiger Technologies
