Back in June I posted about the trouble I've been having backing up
some local directories and I'm no further ahead than back then.

In summary: I'm copying nearly a million small files from the main
disk in a server to another disk in the same machine.
Still on this server, but at a different time, I am backing up the
same million files to a remote server which is completed massively
quicker and I just can't get my head around why this should be.
Let's see if we can solve the problem for good this time...
- First, as a sanity check, please send the command lines for both rsync runs.
- To rule out disk I/O being the bottleneck in the local run, you
could try the same run with "cp -a" instead of rsync.
- Is rsync stalling in the same way you described before (
http://lists.samba.org/archive/rsync/2007-June/017885.html )? If so,
please send straces for the sender, the receiver, and the generator so
we can begin to investigate.
- In the meantime, you might like to try the current CVS rsync both
with and without incremental recursion to see if it works any better.
At this stage I'm close to giving up and am considering forgetting
local backups and getting another server to have two remote backups
instead, which wouldn't be a bad thing.
Have you tried doing rsync over ssh to localhost? That is easier and
might have the same effect.
