Hi Everyone.
This is my first post to this list, and I haven't been using rsync too long
either so if what I'm talking about has already been done, then please
enlighten me.
I've been using rsync lately to mirror debian on my own machine. Someone
told me that rsync can update an existing file with only changes, rather
than downloading the whole file again.
The problem I have, is that a lot of the time the files I'm downloading
change filename, but not by much.. maybe just a different version or
something like that, so rsync downloads the whole file again, one example
I guess would be emacs, it has some biggish files, some of the archives
are 10mb or so.
So, what I'm wondering, is if someone could implement a 'thing' in rsync
to determine if the file that already exists on the system has a similar
filename and size to one it would normally download all over again, and
rename it to the new name, and then update it with the changes, rather
than downloading the whole 10mb again.
If I'm not being clear enough, here's an example of what I mean:
junk-0.7-1.deb
junk-0.7-2.deb
Say both of them are 10 Meg each, and I already have junk-0.7-1.deb, but
I want to get junk-0.7-2.deb, could it be possible to have rsync rename
junk-0.7-1.deb to junk-0.7-2.deb and then download the changes, which
might avoid another 10mb transfer?
Regards,
Robert Davidson.
