I am trying to sync two locations with a large number of small files and it takes forever.
The first sync took 4 days and finished with some warnings.
The second run to check if something was missing (no actual copy) after 24h it hadn't finished and in the log file it showed the same NOTICE entries after 6-8 hours (it could be retries).
The source contains 9.512.000 files and 4.589.000 folders.
The sync reports (below) 23million checks..
After 24+ hours of not finishing (rclone size) I stopped it..
The check with robocopy (the actual copy was done by rclone) has run now more than 26h and still has not finished..
rclone size H:\ -vv
