Summary: Detect renamed files and handle by renaming instead of
delete/re-send
Product: rsync
Version: 2.6.3
Platform: All
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P3
Component: core
AssignedTo: wayned at samba.org
ReportedBy: mlw at infomg.com

It would be nice if rsync could detect identical files with differing names and
just copy/rename the files instead of sending the data all over again.
As I understand it, rsync creates a single long array listing of the filenames
and associated hashes. If it's possible to index on the hashes, cross-checked
with file size, this should be fairly straight-forward, requiring no major
redesign to implement.
The enhancement is easily motivated if you think about what happens when rsync
is used to keep two large servers in sync, and a maintainer renames a top-level
directory on the source machine.
