transfers just the difference. It then replaces the checksum of that
transferred file to the cache. That way one could have a remote data store
and not have to run rsync on the remote system. IE, you could have a mapped
drive or FTP

if you use rsync on a mapped drive, you have no local and remote storage
location from an rsync`s point of view, because rsync isn`t being executed on
the remote node. so if rsync calculates a checksum it`s always transferring the
whole file

Would this still help for online

it would basically download the file with your faster download speeds,

I'm not sure exactly what you mean. You said you were using the -c
(--checksum) option, which makes rsync decide whether to update each

The delta-transfer algorithm reduces only the communication between
the sending and receiving rsync

From the manpage:

With this option the incremental rsync algorithm

Thank you very much.
You set up an ssh server on the machine with the mapped drive

only transferred a few MB using that method and it opened up with the

Will the upgrade to latest rsync will help? We are using rsync
2.6.3.
Thanks in advance,

It shouldn't make any difference because the permission denied error
is coming from your OS, and that's outside the control of rsync.
