I'm trying to find someone with experience or documentation
for the use of pattern matching in samba's smbclient when
using its tar (-T) exclude and include options. My objective
is to write an smbclient wrapper that would allow multiple
items to be excluded via an file containing a list of patterns.
I had my first significant success last evening, but can not
use wildcard patterns. Each excluded file must be specifically
listed. For seven samba shares, here was my total "STRANGE"
report last evening. Normally it seems to be more than a page.
FAILURE AND STRANGE DUMP SUMMARY:
butch //tec/C lev 0 STRANGE

BTW the comments in amanda.conf regarding exclude and samba are not up to date.
# exclude - specify files and directories to be excluded from the dump.
# Useful with gnutar only; silently ignored by dump and samba.
In fact you can do a single file exclude.
But you can't do a list or an append (in my experience).
My smbclient wrapper checks if this "excluded file" is in fact a file
on the samba host rather than the client. If it is a file on the host,
it is assumed to contain a list of files to be excluded.
BTW2, the smbclient man page does indicate it can do Includes as well as
Excludes. For fans of this feature, perhaps it can be incorporated into
amanda backups using smbclient in the future. Maybe it already is, but
I've not checked and if so, the comments are similarly out of date.
Back to my inability to use patterns; The smbclient man page says to do
an exclude on tar file creation you can do -TcX options. Further, it says
adding an "r" (-TcXr) will let the files names to be patterns, either
regular expressions or simple wildcards depending on smbclient compile options.
Whenever I try to add the "r" option, even to an smbclient command line that
excludes files properly with no wild cards, I get a message like "tar_re set on"
but nothing at all is excluded, even things that were without the "r". FWIW,
my samba install is the one supplied with Solaris 9, a version 2.2.???.
I've looked for docs beyond the man page that describe the feature but have
found nothing, and no example command lines. I looked for samba mailing lists
and found either non-English lists :( or ones that in the last 500 messages
or so did not even mention smbclient.
Anyone care to share their experience using smbclient (or I guess smbtar)
with the combination of "X" and "r" options?
