From the howto: http://www.faqs.org/docs/securing/chap29sec305.html
I got some ideas to help me to tar up the OS. I had already been shown how to wrap it into SSH to deposit the tar file on another system, so I tried the following:
tar cpvzf - -C / --exclude home --exclude media --exclude mnt --exclude proc --exclude */lost+found | ssh root@10.0.0.2 "cat>backup-060907.tgz"
But, whereas the howto is talking about --exclude dealing with files, the Centos Man on tar is saying that it applies to files.
So what is wrong? I know the SSH stuff is correct as when I put in something like ls I get a file with result of the ls. Also I had done this without the excludes and of course it died slowing when it got to /media/cdrom :(
I recall that before USB2, when tape backup made sense, I used an "exclude file" rather than doing it on the command line. I also remember that "/"s most definitely affect the outcome. I believe that if you'll look at the info pages (not man) for tar, you'll find a few examples buried in the document that will make the tar part of your puzzle crystal clear.
At the very end of info tar, it talks a LITTLE bit about -- exclude PATTERN.
I guess you have to know what pattern means. So should I be using entries like:
--exclude '/home' ?
I've always thought it was a lot more straightforward to make separate archives of each filesystem you want by cd'ing to the mount point and doing a 'tar --one-file-system -cvf /some/path/filesystem.tar . than to do it in one run trying to exclude any possible mount points you don't want.
