I can't reproduce this:

% rm -rf r d
% svnadmin create r
% repeat 100 svnmucc put -mm -U file://$PWD/r =(dd if=/dev/urandom bs=1k count=200 2>/dev/null) f$RANDOM.$RANDOM >/dev/null
% svnadmin hotcopy --incremental r d >/dev/null
% svnadmin hotcopy --incremental r d
% svnadmin hotcopy --incremental r d
% svnadmin hotcopy --incremental r d
% svnadmin hotcopy --incremental r d
% 13:39

If you delete D:\Test and run the 'hotcopy' command three more times,
does it say 14, 21, 22 in those times too?

What filesystem is D:? Is it NTFS, or a network drive, or…?
