rsync ?

I've heard that rsync can be used to upgrade distro's by only downloading the changes rather than all the data. I've not found a tutorial or how to using rsync to achieve this only for uploading to servers. Does anyone have any suggestions on how to rsync a distro upgrade ie suse 10 to 10.2?

I'm not sure rsync would be the tool for this, as doing so would involve a lot of directories, file versioning issues, etc. My personal favorite tool for this is apt - unfortunately Suse's not enlightened enough to use it.

I'm gonna go put on my flame-proof pants now Smile

Wow, apt on Suse - that's pretty cool. As for all the cool stuff rsync can do, I have no idea - it's an area I'm not familiar with.

I've never used rsync to upgrade but I have used it to restore a system. mabe the following site will help you beter understand it. Just be carefull, use it wrong and you can delete many things. Isn't that right Dave Smile

also as for rsync it's probably overkill but I generaly tend to use the same command when backing up my entire system,

rsync -azv -H -e

That generaly covers all my bases and it doesn't change any files already in place unless they are diferent at the source

Just finished using screen + rsync to transfer 200GB+ of data. Wink

Some of the file transfer tools that are used in conjunction with OTHER tools to perform incremental updates on packages include rsync, wget, various flavors of FTP, and curl. None of these tools by themselves actually upgrade the software, but they are used by various vendors in conjunction with their update tool. Mandriva, for instance, uses curl as one of its transfer mechanisms with urpmi, their software update tool (and I believe wget is used as an alternative if curl cannot work for some reason).

When I worked for Lycoris we did frequently use rsync to update our packages to test during our internal testing cycles and it certainly does save bandwidth by downloading only what has changed. Of course, when downloading the first time, you don't gain anything by using it, but it is a useful file transfer tool.

The wget utility is really handy at times when you may only get a partial file transfer and you want to resume a transfer without having to start over.

The gftp utility is a really handy graphical alternative to using the classical FTP utility.
