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@xxxxxxxx
"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' ?
O.K., I mounted my USB drive, went back in my archived stuff and found
this "exclude" file:
-----------------------------
[root@mavis ~]# cat /media/OT*/extra/FC1*/home/rj/nobackup
/mnt
/dev
/proc
/home/rj/mnt
/media
[root@mavis ~]#
------------------------
You can use this rather than several --exclude entries on the command
by using the option -X <exclude-file-name>.
Whatever suits you just tickles me plumb to death.
Thanks. I could not find any clear reference to the entries in the
--exclude-from file. And I figured out that the reason I was getting an
empty archive was that -C option. I was telling tar to switch to
directory / but not telling it what to tar! Actually, in this case,
there was no reason for the -C. Taking it out got things working. One
question I have is that every so often the -v is showing things like the
following:
tar: Removing leading '/' from member names
/
/sbin
/sbin/dump_cis
/sbin/request-key
/sbin/agetty
Well those were the first ones, and the reason I could catch those is at
that point SSH prompted my for the remote user password.
If I watch the screen (without getting sick with the fast scrolling), I
see other '/' being removed comments.
