Summary: Files always updated even if time is the only difference
Product: rsync
Version: 2.6.9
Platform: x86
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P3
Component: core
AssignedTo: [EMAIL PROTECTED]

I am using rsync to update compact flash cards and would like to minimise the
cycles on them. The cards contain root FSs for a number of identical robots
that differ only in UUIDs, mac addresses, hostnames etc. A large number of
files are generated specially for the update (thus always have different
timestamps to the existing files on the card) but almost always correspond
exactly to the files existing on the CF card. My rsync -i output is full of:
>f..T...... etc/hostname
And other similar files, where the only thing being changed is the transfer
time, which I don't care about.
I accept that the files have to be transferred as the stamp is different, but I
don't see the point of writing the file if none of the data has changed.
I spent a significant amount of time trying to find an option that would
prevent this with no luck, apologies if I have overlooked something.
Finally, this is somewhat similar to bug 3229 but a little different in that
it's not to do with the backup function.
