Actually, you need [] instead of {}, in addition to a comma
instead of a period:
$Conf{BackupFilesExclude} = [ '/proc', '*._nobackup_' ];
Look at the full tar command at the top of the XferLOG file.

Re: [BackupPC-users] clarification of BackupFilesExclude expressions
i'm resending this question, since i don't believe i saw a
response. is anyone else successfully using BackupFilesExclude
with the tar method?
(i'd simply add the "--exclude" args to the tarcmd itself, except
i see from the docs that there's trickery involved in escaping
wildcard characters.)

does anyone use BackupFilesExclude with tar? i guess i'll just
hardcode my excluded list into the TarClientCmd string if i don't
hear that this "should work".
the relevant config lines:
$Conf{BackupFilesExclude} = { '/proc', '*._nobackup_' };
and:
$Conf{TarClientCmd} = '$sshPath -x -q -n -l root $host'
. ' $tarPath --one-file-system -c -v -f - -C $shareName+'
. ' --totals';
$Conf{TarFullArgs} = '$fileList+';
$Conf{TarIncrArgs} = '--newer=$incrDate+ $fileList+';

i'm a little confused. this doesn't seem to be working.
if i look at the XferLOG (or at the running backup tar process on
a client system), the tar command for the backup doesn't include
a --exclude argument. where does the contents of
$Conf{BackupFilesExclude} get transformed and applied to the tar
arguments? the docs imply that they should be part of $fileList, but
in my case this appears to simply be ".": (wrapped for clarity)
Running: /usr/bin/ssh -x -q -n -l root woodruff /bin/tar
--one-file-system -c -v -f - -C / --totals
--newer=2005-12-04\ 00:38:48 .

okay, i'll consider that.

You need a comma instead of a period. Otherwise it should work.

The behavior depends upon the XferMethod, which is tar in your
case. $Conf{BackupFilesOnly} is a set of directories to backup.
Each entry of $Conf{BackupFilesExclude} is sent to tar with the
--exclude option. This provides a set of regular expressions that
are applied to any file to see if it matches, and therefore should
be skipped. Therefore, $Conf{BackupFilesExclude} applies equally
to every directory in $Conf{BackupFilesOnly}. So I don't think
you can accomplish what you want with tar.
The only alternative I can think of is to split the top-level
directories into seperate "shares" (ie: put them in $Conf{TarShareName}
instead of $Conf{BackupFilesOnly}), and then use share-specific
settings in $Conf{BackupFilesExclude}. The causes a different
transfer (ie: tar) to be done for each "share".
Rsync allows richer exclude/include options, and by adding the
right --include and --exclude options to the RsyncClientCmd you
should be able to include just .o files below /lib/modules and
exclude all the others.

[BackupPC-users] clarification of BackupFilesExclude expressions
hi -- i recently realized that there are some pretty big files on
my system that change frequently, and which don't need to be
backed up -- mail index files, for example.
i'd like to be able to flag any file or directory that i want
backuppc to skip by adding a "._nobackup_" suffix to its name.
will this do the trick? (backup method is tar)
$Conf{BackupFilesExclude} = { '/proc'. '*._nobackup_' };
i'd also kind of like to be able to tell backuppc to skip ".o"
object files, but there are places where i don't want to do that,
like under /lib/modules. if i exclude "*.o", can i force inclusion
of all of /lib/modules by putting it into $Conf{BackupFilesOnly} ?
the docs are a little ambiguous on this for the tar method --
i.e., for smb only one of BackupFilesOnly and BackupFilesExclude
is used. but what about for tar, and in what order are they
processed?
thanks,
paul
