Exclusions not working

[John Goerzen]

Good morning,

I wrote the below message to a mailing list for Amanda, a backup system that
uses GNU tar.  However, further checking seems to indicate that the problem
is with GNU tar and not amanda.

A bit of extra information might be necessary for you.  Amanda will run on a
machine and chdir to the relevant directory (/var in this case) before
running tar.  Then it will run tar on ".", which means that all of the files
in the tarfile start with "./".  Exclude patterns such as "./lib" work fine,
but anything with a wildcard, such as "./lib/lists-archives/archives/*" does
not.  The patterns are specified in a file that is passed to GNU tar as an
--exclude-from file.   I'm using tar 1.13.17.

Thankd!

Hi,

In my exclude rules for the /var filesystem backup, I have some lines
like this:

./spool/postfix/private/*
./lib/lists-archives/archives/*

Which, according to the docs, are the right way to do this (there are
sockets in those directories which cause gtar warnings.)  However,
they are ignored!  Also, lines like:

*/no-backup/*

are ignored -- even though this is basically EXACTLY like an example
in the book chapter.  However:

no-backup

works.  (Although it totally excludes the directory and not just its
contents).  Also, likes like this work:

It seems that everything with asterisks is broken.  Patterns without
wildcards, eg:

./lib

correctly exclude the directory.

I have GNU tar 1.13.17, Amanda 2.4.1p1, running on a set of Debian
GNU/Linux systems.

Thanks!
